and answers. So I see that you are there are already some questions in the in the slide though. And as you can see we have some of the EOS Executive Board members online. So I do invite the Executive Board members to feel free to answer any of the questions or to jump in whenever they want. Okay so I'm guessing Jean-François and I all both kind of pick up on Rob's question which is at the top here. So Rob's asking about keeping EOS modular and resisting putting metadata cataloging or AI in a PID system and I think that's a very good idea. I mean we in the last session we had some discussion about sensitive data and obviously not all data can be openly accessible so there will need to be the access control but I think that's to be defined you know in a separate group by the AI task force in the architecture group and that should be referenced then in the PID systems rather than doing things separately in each. So I think you're right about the need to keep things modular. But I don't know if Jean-François wants to pick up on this as well. I agree it's clear that we're in the very early days of the of the design of those functions as we may have seen from the various presentation today and yes paying attention to the modularity and yes what can I say. Maybe Rob has any special idea or is it just related to the metadata cataloging. Rob. Yeah so it was my question was triggered indeed by the PID session that just finished 20 minutes ago but it is very generous general ID that I had that there is it is very easy to be a full prey to a feature creep and to want to integrate functionality very closely but this is a danger I think to the sustainability in the long run of a system as complex as EOSC where I think in the architecture phase that we are in now we really have to make sure that we separate the functionality as well as possible and define the interfaces rather than trying to add functionality to the different components and I am myself a big fan of the functionality of a Unix system designed in the 1970s where really the idea is that each component should do one thing and only one thing and it should do that one thing well. Rob I am the same I am the same generation you are right so I also learn on Unix but and I agree and I think that was one of the reason for my question on the minimum viable EOSC this morning I mean we have to pay attention of what is absolutely necessary and how those it was called mechanism on the slide how those mechanisms are put together I mean the simpler you start and the more you have a chance to keep with this modularity and simplicity we know it will become complex as time goes by right Unix has since you use that example has become complex over time but starting since we are launching this architecture efforts these architecture efforts we should start simple by design right and add complexity only when it's needed you know on our way I agree with you. And then just kind of working down the list to pick up on the second question about the metadata catalog function of EOSC and is there any reason to aggregate metadata at national level of member states or kind of a thematic repository level one of the things I think we need to stress and you'll see this in the rules of participation is that there isn't a single EOSC catalog I mean we have the portal but EOSC should really be a catalog of catalogs it's a federation there's not a single access point and there will be many different catalogs both at national level in some countries or at thematic level so working through the different cluster projects and I think that they're all incredibly useful and communities may have a given place where they go to access data or already that they're using and that that shouldn't change there should be a benefit by aggregating these but you know it's not to say that there shouldn't be thematic catalogs or country-wide ones that definitely should. I don't know if anyone else from the exec board or maybe from one of the projects wants to comment on that. Juan maybe from a rules of participation perspective or somebody from the EOS portal project or? Yes I can comment briefly I think it's written strongly into the rules of participation that there's going to be a kind of subsidiarity approach where individual research infrastructures or infrastructures or projects will have a fair deal of autonomy about how they bring their resources into EOSC they'll be able to set their own terms and conditions of use and things like that however the overarching rules of participation will capture a number of principles or could say could say rules principles guidelines that those extra terms and conditions provided by the participating infrastructures will have to meet when they define their terms and conditions so it's a kind of hierarchical approach that runs throughout the rules of participation. Does anyone else want to comment on this or should we step on to the not so simple question from Sean? Maybe we'll take Sean and Ludex question next so Sean's asking when will average researchers those not in EOSC related projects see the benefit of EOSC and Ludex extending that to say what will those first benefits be and this might be one that it's worth a few of us from the exec board reflecting on. For me the benefit for researchers is that their works easier. They can access different resources, different data sets, different services much more easily because it's facilitated through this kind of federated infrastructure and they can discover resources more because there's an aggregation of different fair data sets coming from all different sources but when that will happen I think is you know until we actually have different services and data sets kind of federated into EOSC you're not going to have that that mass that you know major collection to see those benefits so I don't think it's not going to be at the end of 2020 I think it's going those real tangible benefits that are going to take a few years down the line but for me that's that's the most important one the actual benefit to research making researchers lives easier. Do others want to comment I don't know if anything came out of the MVE session that Carol ran or Juan I see you've just raised a hand. Yes so again I mean I'll just comment on the way shortest phrase the question about when will the researchers see benefits from EOSC. I mean like many infrastructures it can provide a lot of benefit without it being visible to the user and I do believe that a lot of the participation of the projects the EOSC projects will bring forward new features to their own existing infrastructures which will then benefit their researchers without those researchers actually being directly involved in EOSC themselves so I think a lot of the benefit will come through the existing services and research infrastructures if you're working in a particular field and there is research infrastructure serving your field you may well start gaining benefit from EOSC without really realizing that that's coming from EOSC like many infrastructures I think a lot of the benefits are invisible and the researchers the end researchers shouldn't really have to worry about how they are provided so there may be extra features broader datasets these kind of things available to researchers without them really realizing that that's coming from EOSC. Juan this is Carol I was going to say a very similar thing and sometimes we compare EOSC with Eduron researchers do not really care how Eduron works or how they get access to it they just use it of course Eduron is simpler than EOSC is going to be but in my view a researcher might notice the difference at the moment is her repository which they are usually using or provider they are using becomes part of the EOSC system so it's not the researcher as an individual that becomes part of the system but it's the repository and as Juan and Sara said as soon as that delivers extra possibilities within and through that repository then the researcher might notice but as Juan said I don't think the researcher necessarily needs to notice as long as the benefit is there so it's not about EOSC it's about the benefits. So does this answer the question Juan so I know in the chat you've probed a little bit more on the timeline when will researchers see these benefits oh sorry you need un-muting I'll look to do that. Here we go. Okay can you hear me okay? Yeah we can hear you. Okay yeah I take those points and I appreciate that once EOSC is incorporated then potentially you see some more benefits so it's the question still remains when will the average user see it even if EOSC is integrated and they don't know they're using it when will the when do you expect to see those first benefits and as Ludic said what will those benefits be which I'm guessing will be part of the discussions about what the MVE provides. Yes definitely I was about to say that Jean-François it's it's it's the whole goal of discussing what an MVE should be right is that the MVE is is when it is deployed you know scientists researchers should enjoy the use of it right that's as simple as that as general goal now what is it that we need to deliver that EOS needs to deliver for that to happen that's the whole question of the MVE I totally agree. Okay so we have a number of other questions in here so maybe we should move down now to Matthew's question where would you see commercial providers place in an ideal EOSC? I don't know if if Ru puts on the line but I mean in terms of the Tinman document which you may have seen there's a diagram of you know the core and then the federated datasets and then this notion of the EOSC exchange which is the kind of competitive or you know like the the market where you might have different service providers. I'm just trying to look if Ru puts online or I don't know if somebody else would like to speak to that I don't think Ru put is one one reflection from me well while others are maybe gathering their thoughts I mean I I personally think it's really important that that EOSC is open to competition you know for lots of different services they'll or different functions that a researcher might want to perform there'll be various different service providers and you know they should have a choice there shouldn't just be you know one service that's available within EOSC otherwise I think it won't work for the different the diversity of research practice. I see Juan's put up his hand. Yes I can't answer the question I'm afraid Matthew. I can reiterate that it is a question that's on our agenda in the rules of participation very actively being discussed at the moment. Would the rules for a commercial service being provided through EOSC be different than the rules for a public sector service being provided through EOSC? That's a really fundamental question and we haven't yet come to address it but you have an important question there I don't have an answer though I'm afraid. Well there's no answer so much with where they would come so far there's a discussion when they would come in at least the Commission suggests around 2024 that's what they put in their agenda and it's also what we have put into the let's say KPIs we are trying to work on so that doesn't answer the question where they come in but it gives you an idea on when they come in. Excellent thanks. Okay so maybe if we move down to Yin's question so what is the EOSC position in the overall EUICT development landscape are fair, e-infrastructure, open data, part of EOSC or overlaps from different development areas and how we're dealing with that overlap so I mean from my perspective some of these concepts are things like fair and open data they're kind of foundational principles for how we're working within EOSC so I mean initially we'll be focusing on open data use cases but we're talking about all types of data ultimately in terms of EOSC it won't just be open data sets although that's where we're starting we need all data to be fair so that they can be discovered and reused and those data may only be accessible to certain groups of people and then some of these other aspects the e-infrastructure are a core part of EOSC it's part of the delivery the services that are enabling EOSC so I think these are all overlapping effectively it's all part of that EOSC vision I don't know if others have perspectives to offer on this as well. Well maybe I can say the same thing as I said in my session and maybe it's good here to differentiate between again EOSC and the EOSC Association, AI, SBL or Legal Entity this association is going to do work for EOSC but it is not EOSC. EOSC for me is a virtual net of federated data and so you cannot hold EOSC you cannot sell EOSC and EOSC is not belonging to anybody but to everybody so for me it's not part of the ECT development it is part of this connection and of the software based of course running on the internet so as Sara said fair is a thing in itself and important the e-infrastructure are there to make it possible to work with data to compute data to store data to connect data to connect data sets open is a part of fair a certain subgroup you could say and and so yeah these are all overlapping areas that's true and there's many overlapping things in in in the whole spectrum of things but the position is for me very similar to the position of the worldwide web based on the internet as the backbone. Excellent okay so to move then on to Mark's question so some of the things you've heard today in various sessions peered in architecture sound like a natural match of W3C, RDF, semantic web, linked open data but these terms don't actually get mentioned is that intentional I think this is maybe one for Jean-François mainly I think you're right there you know we're talking in those terms but not specifically using them. Yes thanks and thanks Mark this is music to my ears and actually you will find well one I strongly agree with you right two this is connected to what Carl just said I mean this is building a ask on top of the internet the web and the web of data and the semantic web and so forth I mean we should when anybody contributes any any given point in history he or she has to look at what's available and we have you know from UNIX which was mentioned from by Rob earlier to the link data platform which you mentioned Mark all of those technologies that have been developed over the years are available to build EOSC. Now to be more specific and answer your question in the EOSC interoperability framework document that was published yesterday the the 1.0 version and the link data platform is mentioned not as a basis but at least as a possibility so I think it's it's my opinion is a good step in the right direction but but you're totally right I mean at least whatever we develop for EOSC should be able to answer the question you're asking. If I may add to your answer Jean-François as I think this makes this question also makes reference to my presentation earlier this afternoon I don't want to contradict anything here and I also see the linked open data paradigm as actually a good match and perfect use case for the system that we envision here yet I didn't mention that explicitly mainly for the reason that I want those at least the architectural considerations not to not to be confounded at least not too much confounded with the approach that you refer to here as the PID architecture can be a means to link data but it's not only about links and it's actually not only about data so I see this more more generic and more general here it's also not exclusively about open data it's of course also about open data but again there is more and along the same lines it may provide a means to actually add semantics in a well-defined and machine readable way but then again it is not only about semantics but the scope is actually broader that is why I refrain from using those terms but I admit I could highlight these as an important use case and driving example so thanks for that comment sorry I was struggling to find my own mute button then thanks very much for that addition okay so the the next question by Brenna Silva is there any foreseen mechanism to deal with conflicts of interest and to foster multiple developments among onboarding services so I'm not sure I understand the context of this I mean currently the onboarding of services is done through the EOSC portal and there's a process there to and you know fill out a kind of catalog entry for your service so I'm not too sure about the conflicts of interest and waste of foster multiple developments I mean I think that there should be one you know set of clear guidelines of how you federate into EOSC and you know in future that will pick up on the rules of participation so Brenna I don't know if you want to unmute or if anyone else has answers that hopefully would clarify this question I wonder if they are two separate questions one of the conflicts of interest and the other one about resilience through multiple developments and redundancy the conflicts of interest question is very difficult but it's not that difficult from what is already happening in other initiatives and programs so EOSC activities will be funded through many different funding lines each one of those funding lines will have its mechanism for dealing with conflicts of interest and hopefully that will actually cover any financial conflict of interest a little bit tied to the funding whether there are more general conflicts of interest out there that need to be covered at the sort of central level probably are I haven't seen any work on that yet possibly there has been in the sustainability group. Excellent so hopefully this answers Brenna if not I don't know if you want to raise your hand or if you're able to unmute if that if that hasn't answered. Okay so the the next question from anchor how is a researcher going to use the services within EOSC if he or she doesn't know about EOSC at this goes to a comment we were making earlier on about EOSC being invisible I mean from my perspective we don't we don't need people to come to one central catalog or place to discover EOSC services because that's the benefit of federation you know people can use our existing repositories and get the added benefit of EOSC without having to learn you know a new system to go and work with or to go to a new place so that's that's I think how the research is going to discover and benefit from the services because their existing services are actually integrated into it. Then if others have comments or observations to add here no okay so we move on to Sophie's question at the very beginning Catherine reminded us that that COVID's accelerating digitization and do we have a concrete example for EOSC so within the the work plan that should be coming out shortly we've been giving an example of the the embal platform and I don't think Rupert's on the line but I don't know if anyone else if Jessica maybe is and would like to speak about that or anyone from one of the the kind of life science examples that wants to talk about. Sarah maybe I can help you yeah yeah well as it refers to me I feel a little bit responsible of having said that yes so I mean we've very clearly seen with the European Commission Emberly VI COVID-19 research platform which refers to EOSC more than once in its description that the very basic EOSC model is is followed in that research platform and I think that's that is a very good sort of immediate use case and of course the hope is that we don't need a pandemic you know to find other areas of scientific disciplines that can follow this global collaboration but equally I mean there have been very many other activities where COVID really accelerated anything related to EOSC and open science I mean just look at the RDA global working group on COVID-19 with the guidelines that came out the European Commission published guidelines for researchers along COVID-19 we've got the code data RDA data together initiative so I think yes what we have clearly seen and what I always think is that open science really needs rewards and incentives and I would like these to be positive but I think COVID-19 has shown that even if we don't have positive rewards and incentives a pandemic a threat to humanity makes us all collaborate so now we need to turn that around and say okay we can do that in an emergency we should be doing this on a daily basis this is how we should be doing science in the future thanks thanks very much Katwin so the next question from Yuri de la Mar do any of us have an opinion on how EOSC could benefit from the cloud federation initiative in the Commission so it builds on the French German Gaia X project and has innovation at the core oh Carlos yeah I just see in chat you could say a few words on the platform if you'd like can you unmute yourself or shall we just unmute you not here we go I'll unmute or maybe I don't have permissions to unmute you can somebody who's maybe a host do you hear me now yeah can hear you now yeah okay then maybe I'll say a two words about this data sharing platform that embal is leading so this actually represents one of the ten key areas under the era versus Corona action plan that the Commission launched on April 7th this one priority consisted in setting up a research data sharing platform as a real implementation case for EOSC and the objective of course was to speed up and improve the sharing that we use the processing of research data and method data related to SARS-CoV-2 and and COVID so the Commission has called on active EOSC stakeholders in the life sciences such as Emily VI elixir and other partners and the idea is to create an open trusted and scalable environment as a blueprint on which EOSC can then build on so this was actually conceived as an important part of building the European Open Science Club and it's a thematic priority pilot to realize this vision excellent thanks very much Carlos so in terms of your these questions does anyone have a view on the cloud Federation initiative perhaps some of our current cloud providers or or we can mull it over and come back to it maybe if we move on to Fortis's question and the Federation of thematic infrastructures is key for EOSC but oh hang on that's just jumped it's a level of federal if the level of Federation is high then its added value will be higher and the cluster projects have a major role in this but they don't need to stay at just verifying their data they could also federate their services and tools and workflows I completely agree I think it's really important that you know we we address EOSC in a very kind of comprehensive way it's not just the data it's all of the services and tools and it might you know for different communities it might be different you know different aspects of those cluster projects and different tools that are the priority to federate initially or certain data sets which have high reuse value or a lot of cross-discipline use that are important to federate initially do others from the exec board have views I'd like to give on this I'm happy to comment on this too and I also agree with Fortis's point which is not really a question it is a point but I agree with I do think there's a balance to be struck as well though the more broadly we're just in standardization generally the more broad you want to make a standard the more difficult it is to get agreement on that standard so we have to balance the the breadth of standardization against the speed with which we can do it so hierarchical approach where research infrastructures federate into clusters and those clusters federate into the EOSC is a way to kind of try and address that balancing so yes Fortis I agree with you as well okay excellent if we move down then to Ignacio's question I think that services are highly forgotten when talking about EOSC I believe EOSC goes beyond data sharing and processing services a key to avoid users downloading tons of data without any means for processing them we do in the strategic implementation plan we talk about EOSC being a platform a place where researchers can bring together you know the data with all of the different tools to to do that analysis I don't know if that's maybe something that isn't always understood that it's it's an environment for doing work as well yes again I agree I think there is a slight risk that you will get researchers downloading data without more data than they really have the ability to use for me this is an acceptable risk as long as it doesn't impact on the bandwidth enough to limit other people's use of EOSC but it is something that we could monitor through the monitoring and accounting system in the core and just note if there are any particularly high users you could perhaps inquire as to why they are making huge downloads I think something else is meant here if I understand correctly I don't know if Ignacio can take the floor him or herself but I think it's meant here that without computing power there's nothing you can do with the data yes of course if the data sets are large and if you need to compute on them you need computing power but that is not EOSC that is computing power that exists and that you can use either you have it yourself or you get it from somewhere else through the internet or remote or whatever but EOSC is not computing power so a service service offering computing power can of course be given by a service provider so I unless I misunderstand what EOSC is or this question but I don't see it yeah there's a bit more in the chat here is also Matt Mattage has said he's surprised about the this concept of highly forgotten he thought everything in EOSC is you know a service so platform service everything as a service and that it would be brokering computing services yeah so he doesn't understand either Jean-François as one of the co-authors of the SIP do you want to come in on this as well well it's a little bit like we've had this conversation many times the problem is what is so I'm referring to the web right so some people say the web is HTT URL HTTP HTML well those are the components that were miss when it started of course it's much more now but when he started but again this were the components that were necessary to get the web started but immediately you had a web server and and a minimum browser right so and you were offering services on top of it so it's almost a matter of vocabulary definition there is one thing which is what is it that what are the components the mechanism as we mentioned them this morning that needs to be developed in order for us to take off and then thousands of flowers we blossom there will be so many services developed any webs web server today there are millions and hundreds of millions of them today they're all services they have been developed on top of a set of elements the documents that have started to exist and then were deployed so I don't think this debate is as depth right it's it's a misunderstanding on the vocabulary right that is eos could not exist if data are not fair are not available openly and and they are not the mechanisms to name them identify them discover them and so on and so forth as we said this morning but then it will have a value for scientists for example as was asking in earlier questions you know if scientists use eos without knowing it it will be because there are so many services that scientists will know that they will use on top of eos right so I think it's it's clear that eos will be a success when thousands of flowers with a blossom meaning thousands of services would have developed on top of them excellent thanks very much on France cloud so the next question down from yin again will eos actively adopt AI approach and the mood to AI based eos this may be one for the architecture group no again eos will not adopt I approach eos will allow AI based applications to be developed on top of the web of fair data so it my question what does adopt means right it will enable again thousands of AI approaches on top of it right and the sky will be the limit I mean that the the limit of the imagination of the scientists or the you know will be the the limit of the use of eos right I very much agree with John Francois so AI could benefit from having eos having more easy and in a more standardized way and and more data available but so eos does not have to adapt AI exists in itself and can make use of eos like euro HPC can or high performance computing or computing in general sure they can use more and more easily data but it's not a matter of adopting by eos and then if we jump down there's one from from Joan and what's the role of citizen science citizens in general and citizen science in particular in eos can citizens contribute data and more yeah maybe maybe this this is same as the public sector and the private sector in a later stage let's say starting 2024 around that time hopefully more and more let's say possible uses of eos can and will be there the private sector the public sector and the citizens which I would see in the same category for the time being as the public sector so yeah the role of citizen and citizen science then can grow that's the way I see it yeah agree other reflections on this or we good to move on we're slowly getting through all of your questions I think we way we've just got a few left now so so one from Kurt about the n-rends how to bring the n-rends initiative together in in eos sharing research data and integrating data repositories I'm not familiar with those initiatives so forgive me I couldn't say what about the ontologies standards API so their plans for a for a minimal metadata set I think that's that's actually a really important point you know we've talked already about many different catalogs being within eos we do need to you know kind of allow cross search or integrate so we do need to define a minimal set of metadata there and I think there are like there are things we'd we'd recommended in the turning fair into reality report that can be looked at I think I encourage her to engage into the discussion about the eos interoperability framework especially at the semantic layer yeah remember this morning we explained there is the technical layer semantic layer organization organizational layer and legal there the the question relates to the semantic layer which is recognized in the eos interoperability framework and in the in the next version of the document there will be more depth in in addressing the semantic layer and what is it that should be provided by eos meaning federating existing initiatives in this in this domain and so the answer is yes of course there is a need to understand what the federation that eos is will do with regard to the semantic layer definitely yeah and I noticed one thing in chat and people haven't always known who's speaking so so just to clarify for people and most of us answering questions are from the exec board so I'm Sarah Jones from the digital curation center who chairs the fair working group Jean-François from the architecture group and Carol who's the chair of the exec board overall and also Juan have been answering questions and catch when he's the vice chair of the board and so we just have a couple more and then I think Sara Garavelli has some closing remarks as well so so maybe if we take Sean's question about in order for communities to integrate their services into eos community service managers will need an understanding of the benefits and the rules of participation and training do you think the eos projects are currently providing the correct level of support and my personal take on this I think it's incredibly difficult for the projects at the moment because everything's a little bit of a moving target so we you know we have this executive board and governance stretcher set up running in parallel so as those rules of participation are being agreed you know they will then once they've been validated need to be implemented by the project so at the moment the two things are kind of going on in parallel but I think you know this is in all the project plans and the forthcoming in for eos projects will continue that service onboarding as with everything I'm sure there's always scope for improvement and I think that's one of the real benefits of having consultations like this because we need to understand what's not working and improve on that. Other members of the board are involved in the projects as well I don't know if you've got comments here around how we help people integrate into eos. Yeah I'm not sure whether Sean's question is asking whether the projects are providing enough communication within the projects or whether they're communicating with their user communities outside the projects. In either case I think what you said Sarah is neither I answer this is a very difficult area we have to consult as widely as we can cope with but the ambitions of eos are to address such a wide community that it's almost impossible to communicate widely enough so again it's a question of balancing resourcing and ambition. If there are Sean if you do have specific suggestions for ways to improve communication please get in such through one means or another because it is something that needs to be carefully addressed. I don't know if Catherine is still there maybe she has something to say about communication. Oh yeah sorry go ahead Catherine. Sorry no I mean from the communication I mean one of the things that I think Sarah you also noticed that the eos liaison platform from the secretariat is a little underused and I think this is this is a very good way of communicating with stakeholders directly which is one of the focus we give at the moment to any of the eos communications very much the how not necessarily the why but the how of the eos and communications around that I think I would always point everybody to the eos secretariat website then the eos liaison platform otherwise the on the why of eos the communications working group is quite engaged at this point in time as we are very clear that we need to also you know increase our wider communications on why we are having the eos in addition to to the how and the what so yeah watch the space thanks. So my one comment is I think the eos liaison platform is great however I don't think that the stakeholders necessarily know that they are stakeholders and that I think is part of the problem it's not clear who eos is aimed at. I think that's a very very good point and obviously the communications team of the eos secretariat is listening to that and I think we will we will be looking into that so thanks for making that point. Yeah and we discussed this a little bit in one of the fair sessions earlier on today about ways to reach out to the community as well so I think there's things we can improve there. So Per I saw in the comments can speak to the GAIA-X question and I think you've been unmuted now Per. Okay hello hello everybody now so I am not an expert on GAIA-X probably you know more about it than me but with my I have my I can I can pretend that I have my eos hub shut on now since you can't see me but I have. So I think it is a very relevant question here though GAIA-X is a like an eos for industry we could say and comes from its I mean keywords like data sovereignty independent Europe and so on being independent of the big American aggregators and so on and but and it's mainly say industry and and government governments behind this but I think it's very important to make the connection here and making sure that use of standards architecture and so doesn't diverge because through the GAIA X initiative that could be a very good or enabling the industry to make use of the open data if we make sure that it's open in the sense that that also they fits the GAIA-X architecture and they can make efficient use of it and then if we may can prove that we can get a much more positive attitude from industry and much more a lot of positive things could follow out of that I think so it is a very important thing here that Yuri brings up that should be looked into really because the the architecture now is of GAIA-X is taking form I mean when talking about the service mesh a federated service mesh a federated data mesh a real-time service mesh and things like this and it should be studied really. Excellent thank you very much Per. So just to kind of draw this to a close some of the comments in here some of the final kind of questions are more kind of recommendations like about the citizen science initiative or agreeing on the communication to stakeholders to help them realize their importance in EOS. There are two that I think I'd like to pass on to the secretariat project so one from Fotis around the engagement from end-users so researchers I know the EOS secretariat project specifically has a work package where they're looking at the engagement and researchers are one of those and also Tiziana's question about the interest groups announced earlier in 2020 whether they'll be kicking off in the coming months I think it's the secretariat project who are coordinating those so I don't know if somebody can speak to these two questions and then we should hand over for a wrap-up to Sara Garavelli. If you hear me Andrea from the EOS secretariat hello hello everybody so I start from the the question of Tiziana yes interest groups are actually being kicked off we are reaching at this moment some grounds of where to start from so you will you will receive in the next 10 days an announcement about interest groups especially the first one being the one on the glossary that will present its first activities and indeed the the first grounds of common action from all the EOS related projects and the first one the other question sorry I don't see it anymore if someone can repeat it for me. So the other question was about the engagement of researchers so I think TUV and have been working on that stakeholder group specifically. Yes indeed TUV was the pioneer that has been dealing so far and will continue dealing with the researchers in the stakeholder engagement work package and several workshops have been and have been already done in quarter one of this of this year and others are going to come of course the format as it happened already in the EOS Cup week is one good example is going to be changed and but this is indeed an activity this is continuously being developed. Excellent thank you very much Andrea okay so well we've come through to the end of the questions as well so thank you from me for all of you staying on so late in the day and continuing to ask the questions and from the rest of the exec board for getting involved in the consultation event and giving us feedback a reminder that there are various documents out there to feedback on and also that you know we we're relying on on you to shape those directions for EOS so do give us feedback on what we're releasing but also how you want us to engage with you and I'll just hand over now to Sara Garavelli I think you've got some closing remarks maybe instructions for people yes thank you very much Sara so first of all I would like to thank all the participants for staying online for the full day but in particular I would like to thank all the members of the EOS Executive Board and the working group co-chairs and also the colleagues from the EOS Secretariat project for the support provided today so thank you very much I think it was a very an excellent event and all the presentations of today are already online on the EOSCUB website and the recordings will be published as they are available on the website I remind you all that tomorrow there is the first day of the EOSCUB project now you can see on the screen the agenda so we start tomorrow morning at 10 a.m. like today so please connect at least 10 minutes before the start of the event we start with an opening plenary chaired by Titiana Federari from the EGI Foundation and the EOSCUB coordinator and then we have a series of breakout sessions and so avoid the issues that we had this morning with the zone breakout rooms also tomorrow we will be using different zoom links so I will send you an email right after the end of this meeting with all the details so you will have all the information on how to join the sessions tomorrow and with that thank you very much I wish you all a nice evening. Thanks Sarah thanks for everything you put into a range at all.


is Diddy K and I'm back with another video. Put me on your big screen video or even Samsung. Either way, go, it's time for us to get these funds. Now, today we're gonna do something that we've never done before and that's actually give you guys a weekly recap. Now the reason we're doing this is because we no longer post five times a week. So we're gonna post one to three times, well, two to three times a week. So I'm gonna give you guys all of the orders that I had last week. And this is gonna be from Friday to Friday. Also, make sure you smash that subscribe button. Also, give me a thumbs up. It took me a while to make this video and all I'm asking you to do is give me a thumbs up and if you are not subscribed, make sure you smash that subscribe button. It's time for us to slide. Now, on Friday, we had two orders. Order number one was from the carrier company. We drove 56 deadhead miles, seven miles loaded, so 63 miles altogether for 110. We're about to pull up and get it in. Let's go. Just like that, we are here at the pickup location and guess what, we are late. We are late because I'm talking about that traffic was critical and everything was moving slow because all of the snow, it was big snow outside, baby. So it's slow last night, but either way it goes by to get our pockets tight. Good morning. How you doing sir? I have a load to pick up to go to Walker Shaw. That is game time. It's time for us to get on the grind. Let's go. How you doing? Yeah, I noticed that it wasn't plow right here. So I didn't know. Oh, you did a great job, huh? Yeah, your name's Steven, right? Pat. Are you Pat? Yep. Hey Pat, how long have you been driving a Ford truck? How long have I? Yeah. I've been driving about six, seven years. I've seen people drive for way longer than you. They, man, they don't drive like that. You see how you just use the angles and people don't normally do that. Yeah, let's just pick it easy, man. You know, and then you just gotta realize how far you gotta go without breaking anything. That's the most important. Oh, they love to break stuff. They love that.  Oh, man, rocking, yeah. You got it, dude. Yeah. Router number two, get this money, is what we're about to pull up and do. We got an order on freight. We're about to get to this money at all. Hey! The pickup location is Lowe's. We're all picking up three items. Well, ain't really three. Y'all see what I'm talking about? We're gonna drive five miles for 5515. We're about to pull up and get this green. Let's go. Let's go check. We are here at Lowe's to go and get this dough. Get a pump like Chris, though. Come on in. How you doing? I have a freight order to pick up. Thank you. You have a good one. You too. Y'all see what's going on? We got this big wood. Paul, we got big wood in this joint. Time for us to get on point. We gone. Y'all know my nickname wrong. It's time for us to get it on. Let's go. Just like that, we are here at the drop-off location, baby. Let's see where they want to put this joint at, baby. So we can see. You have to not guess what. It's going in front of the garage. I ain't gonna play no games at all already. No money, man. Did he cave in it? Ain't no thing. Well, the customer did not answer the door. So we're going to put it right here by the garage. Then we go slide. Now we got to step back here with a photo of your noodles. We gone. So on Saturday, we actually made $60 to zero. We made zero dollars, unfortunately. Now, I also want to tell you guys this.  Because it's been very slow in my area. So I kind of been trying to stay at home a little bit longer until we get an order so we can go out and get an order. And unfortunately Saturday, we didn't get anything. We didn't get no green, baby. So it is what it is. Now, Sunday, it's time for us to pull up to get this Monday. We had another load from the carry company. So just so you guys know, we're supposed to pick this up Sunday at 12 p.m. and drop it off Monday at 6 a.m. We're going to drive 38 deadhead miles, 54 miles loaded. So 92 miles altogether for 150 RRP nifty.  That's not the greatest of orders. But the thing about this is the pickup location is right around somewhere, which is like 38 miles as you guys heard. Then we're going to go back home. Then on Monday morning, we'll go out and we'll make 150. The drop off location is literally probably like 30 minutes from my house, probably 25 miles away from my house. So it's not bad at all. It's time for us to ball and I stall, let's go. How you doing? I'm going to have a lot to pick up to go to start of it. Okay, how many people do you need to be like five minutes? Okay, all the right wishes. All right, thank you. We are back for the 15,000 time. Oh, this joint closed. This joint locked. I'm trying to call this number. Shoo. Hey, hello, sir. How you doing, boss? I went to this door right here, but it's not open. No, we closed that too. Oh, you are closed for the day? Y'all not shipping out anything else? Okay. Because everybody's leaving. Oh, okay. All right, thank you. So as you guys just saw, it did not work out in our favor. We went through the pickup location. The stuff was not there yet. They told us that it was okay.  I didn't hear anything from him. I went back in.  It still needs to be cleared. Wait again, nothing happened. So I'm like, you know what? Forget this. We're about to go to this little restaurant and cause she was going to chill a little bit. Went over there, ate some pretzels with the cheese and all that. Chio, they had the football game on. I don't really watch sports, but we had it on. Something to do instead of sending the van to get them bands. I went back at two o'clock because the dispatcher told me that everything was ready. They told him that they'd be good to go. I go there. The place is actually closed. And I had a master game plan I was going to do. So after we was going to drop off that order on Monday, we had another order from Frank. We was about to get to that money though. Hey, we were about to get to that money, but I actually had to cancel it. It wasn't the greatest order, but it wasn't the worst order. And the reason why I was choosing to do this order because I'm explaining it right now. Now it was actually a car order. We was going to drive 95 miles for $106 or 60 cents. I know, I know, I know. Why would you do that in the Sprinter van? This is why we was going to do it. We was going to go to the drop off location, drop that off, right? Then we was going to shoot up north, like 30 miles, I think it was 35 miles up north.  So that was the plan. That's prime location to get loads, but end up not happening. That order got canceled. So we got $100 for the cancellation and then we got $40 for detention because if we literally sat there for three hours and we didn't get nothing.  So that's what happened on Sunday. We only made $140 of that Monday. Now Monday rolls around. And guess what? Guess how much you made? Since it's a zero, we sat out there from 9 a.m. to 1.15 p.m. and we did not get one order. Not one order, not one load, not one nothing. It was critical. And that's the reason why I was telling you guys earlier that I don't know if I want to want to keep on just driving around and stuff. It gets, it gets old after a while. I know everybody need to go out there and check the money out. It gets old after a while. You sit in the van doing nothing. It gets old. So that's what we had to do. It is what it is. We ain't complaining. We maintaining. We gon' keep on getting this change. Switching lanes. Switching lanes to Tuesday. Now on Tuesday, I had one roadie, roadie, roadie with a devarent. I had a roadie order. It was one TV driving two miles for 2135. It was a great time to be alive. I'm gonna grab this hand, put it in first. You got it? Alrighty. Thank you very much. We have a good one. This one right here. All right. And just like that, we got this joint strapped up. Now it's time for us to go out here and run it up. Let's go. No problem. I tried to get it up to here with this. So I started it. Yeah. Yes, sir. Is that it right there? I have to take a photo and I'm good to go, sir. Okay. Step back in with the photo. Thank you guys very much. Guys, have a good one. You too. So after that order, I went home. Again, I told you guys I ain't about to be dropping around wasting no gas and getting no cash. Went home, I'm watching YouTube, I'm chilling a little bit. Not really. I don't really like to chill though. I really like to go out and get this money. And guess what came in?  Drop off, freestyle to me. Like, hey, can you do this order? I'm like, uh, they was trying to make me do two pickups and one drop, which was gonna be like, take like three and a half to four hours.  I'll say absolutely not. If you haven't watched that video, make sure you go watch it. So all together, it was 120 miles. This was the car order, of course. And we got to pay 225, but to pull up and pick up the prize, let's go. And just like that, we are here at the post office. This is the pickup location, baby. This is my first time doing this. So I don't know what's that I'm supposed to do or how I'm supposed to do it, but y'all know I spent the half fluid. I gotta take y'all with me. Dancing in video like we did, baby. Get in. Dang. I don't know where I'm supposed to go. I'm guessing I'm gonna go over to this room right here. They got a lot. Sheesh. They just saved me from standing in that line. What you got? So I have a thing called a multi-plan. This is the tracking number. They told me to come to the front. Y'all see it, baby. This is all we dropping off about to not take socks off. It was nice and sweet.  That lady saved me. She saved me from standing in that line like that. So it's time to hit the road and get our pockets on the floor. Let's get it. Hello. How you doing? I have a gift for you. What do you want? I have a gift for you. Usually you receive the mail. Oh. Who's looking for it? I meant the wrong place. This sweet 100, correct? Yeah, multi-plan? Yeah, they told me to come here. Oh, I bet you he was just up here looking for it. I was on the phone. Oh, okay. If it's somewhere else you need me to take to, that's fine also. How you doing? Oh, I'm just sending you a note. Oh. Is that what you were looking for? Here you go. Awesome, thank you. Let's take a picture really quick. What's your name? Garrett. My God, Garrett, you know what the photo was? Mac. I'm good to go. Thank you. You guys have a good one. Yes, sir. Now, it's Wednesday and we only got one load. That's it, that's all. It was from the carrier company.  So 46 miles all together for 110. Guess what we're about to do? Get these dividends. Let's go. We're here now. You old noose. Got a couple push shocks, a couple old schools. Dang, y'all see this? We got the van. I don't know how they're going to do this. Or maybe they take the, oh, they can take the fork truck down here. I don't know what they're going to do. Or how they're going to do it. I'll stick that on the floor. Let's get it. Picking up. Going to Hanover Park. Hanover Park. I'm in the Sprinter van, so. All right, I'll text you your shipping guy and I'll ask where he is. Okay. All right, thank you. And just like that, we gone. Let's go. And we are here at the drop-off fee. So we can get busy. I saw them just unload somebody else, but they called to get on me. I don't know which one works. So I've run both of them, Jones. Time for us to get it on. How you doing, sir? I'm gonna have a drop-off to you guys from willing. Thank you very much. And now we are on Thursday. Thursday, we did the second longest drive we've ever done in smoke. Ain't no joke. And we actually went from Illinois to Dubuque, Iowa. So huge shout out to everybody in Iowa. We're gonna drive 23 deadhead miles, 159 miles loaded, sorry, 182 miles all together for 350 RRP Nipsey. Let's go. And we are here at the pickup. Hopefully it'll let us wind it up, baby. Bill, Bill. I don't know how long I gotta ring that joint. It says I gotta wait till it's light turn green so we can get this green. Guess what? We are early, so hopefully. We're going in again, coach. We are early, so hopefully we can get in and get out like a bank robber. Hello. Hello. How you doing? Am I supposed to go around this way or come this way? What do you want? I'm picking up a load to go to Dubuque, Iowa. Oh, but you said 10, no? Yeah, 10, yeah. I'm a little early, too early. Okay, so just come back in at 10. Okay, thank you. And just like that, we are back at the pickup location yet again. We were actually 40 minutes early. We were trying to come early so we can hit the roll faster. So unfortunately it didn't happen. Windwrapping, windcapping. We're about to start snapping. Let's get it. Thank you very much, sir. You're number eight. Number eight? You got Calcopeler, right? Yeah, a van. Yeah. Number eight? Yeah, I will for you. Okay, I'll meet you there. So it's four pieces and the one thing. Yeah, I have four pieces. Okay. One, two, three. Okay, you're gonna run the start of this joint. There you go. Perfect, right there. Like that? Yes, sir. Yeah, cause they want this four pieces. And just like that, we got a long ride so it's time for the slot. Let's go. Dubuque, Iowa. We are here, babe. B-E-E. Trying to get a bit easy. Shoot, shout out to everybody in Iowa. Comment below and let me know if you're in Iowa. Shout out to y'all. I'm talking about the ball and I saw. Is it going or anything? Maybe I guess somebody's supposed to be right here. How you doing, sir?  Over here, dude, right here. Okay, all right. Thank you, sir. All right. I'm trying to pull up in the driveway with this money, but guess what? We barely made any money on Friday. I was at home editing this video for you guys. My business partner was already out doing what she was doing and she did get an Instacart order. It was two orders. I don't know how many items because we don't got the screenshot so I'm out for eight. It was a sprinter moment thing. Don't eight, I don't want no problems. Sprinter moment thing. Now she chose 3.2 miles and made $47.51 on an app and she also got a $10 tip off the rip. Sounds a little flip. Guess what? The game is over. So all together this last week, we only made $1,069 and one cent. Not enough money to pay the rent. We was driving around the bends with no 10, but it was a terrible week, baby. It's very slow in our area right now. I don't know what it is. I mean, I guess it's because it's the beginning of the year. It is what it is, baby. This is coming with the territory. So if you plan on getting into this business, just be ready for stuff like this to happen. We ain't rapping. We ain't capping. We snap it. I hope you guys enjoyed this video. Again, if you're not subscribed, make sure you smash that subscribe button. Also, give me a thumbs up. And don't forget to throw them seas up.  You already know what to do. I'll see you guys on the next one. We gonna be flooring. You already know it. It's DDK and I'm on my way.


On Street Views, Nigerians narrate your deals with online banking. Take a lesson. Some people will borrow money from them. They will law you that the money you are going to pay is 100,000, that you are going to pay 105,000. At the end of the day, if you default once, the town starts charging you exorbitantly. Before you know, they say the one you paid already has gone. So the government did not, they were not proactive at all. They were just reactive over the matter. And they have allowed people to get into it before it goes in there. Who gave these people licenses? Where did they get the licenses from? How did they start to operate? In the first instance, they gave me re-operating. Where was their source of money? Not by sealing them off. Let us know the source of money. We are having a challenge of, you borrow loan, let's assume you have to repay back in the month time. If you don't pay back, they will start tracing your contact and start telling you how frosty you are and the rest. It's a very bad experience. I think most of them need to shut down because if someone asks for a loan, the necessary thing for you to do is ask for their details. If anybody is used as a guarantor, you need to find out who that person is, their details and confirm if they are willing to be a guarantor for whoever is asking for the loan. Because I just got a text message now. It said Rafiat Ali, I don't even know who that person is. I have better experience about them because there was a time somebody borrowed loan. A friend of mine borrowed loan from one of those bank. I won't mention the name for now. So, I was not called before he borrowed the loan. I was not informed. I just got a text one day that a friend, somebody borrowed loan from me using my name, my phone number, my name as a guarantor. And a text that I was on call for, they were saying to me that using as a guarantor that I should try to look for such people, such person. So, I have to start calling the friend. And the number is not going to... And most of the time they use number that you can't reach out to again. So, it's something, online loan is something good. But the way it's been handled, the way it's been done, it's not ethical.


Next question, find the equation of the hyperbola whose 4 psi are at minus 4,4 and 6,4 and eccentricity is 2. Nidish, what's your response on this? Teyugia? Teyugia? Snigda? So first draw the diagram for this, everything will be very evident from there itself. So your 4 psi is at 6,4 and minus 4,4. Right? So let's say one is 6,4 and the other is at minus 4,4. Okay, so yes, this is the nature of your hyperbola. Okay, remember the center of this hyperbola will always be at the midpoints of, always be on the midpoint of the line connecting the 2,4 side. So this will be your center and center will be the midpoint which is going to be 1,4. Center is going to be 1,4. Okay, so all of a sudden I have seen the attendance the number of people watching has grown up. So it's important to call people's name few times. Right, now what, how will I get my A and B? Okay, very simple, the distance between the 2,4 psi is 2Ae. So it is basically 10 in this case, right? So the distance between let's say S1 and S2 is 2Ae. Okay? So e is given to us as 2, so A becomes 5 upon 2. Right? Now it's a case where the eccentricity is 1 plus b square by a square under root. So e square is 4, b square is unknown and a square is 4 by 25. So this implies b square is going to be 75 upon 4. Now we can always write down the equation of the hyperbola once we know a square, b square and the center of the hyperbola. So your final equation will be x minus 1 the whole square by 25 upon 4 minus y minus 4 whole square upon 75 by 4 equal to 1. Okay, now I am leaving it at this stage because I don't want to waste time simplifying it. My idea was to convey the concept. So how to deal with the equations when some critical information about the equation is provided to you. Next concept that we are going to talk about is the concept of focal distances, focal distance of a point from the 2, 4 side. So let's say I take a standard case of a hyperbola. So let me pick up a point, let me pick up a point over here. So what are the distance of this point from this focus and what are the distance of this point from this focus is what I am interested in. So let's say this is p and let's say this point is S1, this point is S2. Okay, so assuming this point to be x1, y1, let us find out S1p and S2p that's called the focal distances. These are called the focal distances.  S1p is e times pm1 which is going to e times x minus x1 minus a by e. That is going to be ex1 minus a. This will be e times pm2 which is going to be e times x plus a by e which is ex1 plus a. Okay, and when you take the difference of these two mod of S1p minus S2p you are going to get 2a. This is a very important piece of information for us which says that you can also define hyperbola as the locus of a point, locus of a point which moves in such a way that the difference of its distances from two fixed point, two fixed points is a constant and this constant is lesser than the distance between the two fixed points, between the two fixed points and not zero. Is that fine? So please remember this, this definition is very important in solving questions which come related to complex numbers also sometimes. Next is the parametric equation of a hyperbola, parametric equation of a hyperbola, x square by a square minus y square by b square equal to 1. Okay, now normally we represent the parametric equation of a hyperbola to be x equal to ac theta and y is equal to b tan theta, right? Where theta is a parameter which is called the eccentric angle also, theta is called the eccentric angle, it actually behaves as a parameter. Okay, now let me just show you what is this eccentric angle actually. So let me hide this. Okay, so as you can see on your screen over here, I have drawn for you a circle whose diameter is exactly the distance between the vertices. Okay, by the way, this circle is actually called the auxiliary circle. This circle is actually called the auxiliary circle, right? All of you please pay attention over here in this auxiliary circle what I'll do, I'll make an angle, I'll make an angle theta from the origin like this. So let's say this is angle theta. Okay, and from this point I'm going to sketch a tangent. Okay, so what I did, I took angle theta and I sketch a tangent at this point and this tangent I'm going to take the point of intersection over here and scale it up till it hits the hyperbola. So what I did first, I made a 90 degree tangent over here. This tangent meets the transverse axis at this point. Let me name this point. Let's say this point is the point P. From this point I took a perpendicular up to cut the hyperbola at, let's say, point Q. Then we say that the coordinates of Q will be AC theta comma B tan theta. So this is how this angle theta is related to this point Q. Many people wrongly believe that this angle is basically the angle made from here to this point, right? And the thing that this angle is theta. Please know that angle is not theta. By mistake also, please do not take that. Is that fine, guys? Now, if I take the parametric equation of, if I ask you the parametric equation of this x minus alpha square by a square minus y square, sorry, y minus beta whole square by b square equal to 1, then what would be the parametric form? The parametric form would be x equal to alpha plus AC theta and y will be beta plus beta tan theta. So this will become the parametric form. And if you have the conjugate x square by a square minus y square by b square equal to minus 1, then this parametric form would be x equal to a tan theta and y equal to bc theta. Okay? Now, guys, various type of parametric forms are also possible. These are the most commonly used ones. So I'm not saying this is the only way to represent, you know, parametric equation for a hyperbola. Okay? So let us take some questions to, you know, appreciate other forms that can also be possible. For example, let's take this as a question. Prove that a by 2, t plus 1 by t comma b by 2, t minus 1 by t, this point lies on the hyperbola and get the equation of the hyperbola as well. Get the equation of the hyperbola as well. Yeah, so here t is a parameter and you need to actually eliminate t in order to get the equation of the desired hyperbola. Correct? So first, let us look into this aspect. So A x is equal to a by 2, t plus 1 by t and y is equal to b by 2, t minus 1 by t. Okay? So I can say 2x by a is t plus 1 by t and 2y by b is t minus 1 by t. Now when you square both the sides, so you get t square plus 1 by t square plus 2. Here you get 2y by b whole square as t, sorry, this t square will not come. This becomes t square plus 1 by t square minus 2. Now let me call this as 1. Let me call this as 2. Let's subtract 1 minus 2. That gives you 4x square by a square minus 4y square by b square is equal to 4. Drop the factor of 4. So you get the equation to be exactly the standard case of a hyperbola. So even this could be used as a parametric form. So my point is don't be like under the impression that it is always ac theta comma beta and theta. Okay? Next question. If e and e dash be the eccentricities be the eccentricities of a hyperbola and its conjugate and its conjugate, then prove that 1 by e square plus 1 by e dash square is equal to 1. So please type done if you're done with this. It's an easy problem. Probably you would have done this in school as well. Alright, so only Lalitha could do it. Simple. So for the normal ellipse, we have e square as 1 plus b square by a square which is actually a square plus b square by a square. And for the conjugate, this will be 1 plus a square by b square which is actually 1 plus a square by b square which is actually again a square plus b square by b square.   That's going to be 1. So next concept that we're going to talk about is the concept of position of a point with respect to a hyperbola. Position of a point with respect to a hyperbola. Can you see the screen? Alright, so let's again make a hyperbola. Now a point can be at three locations with respect to a hyperbola. It can be at a position a, it can be at a position b or it could be at a position c. Okay, so let's say the point a here is, the point here is x1, y1. Okay, let's say x1, y1 is the point and I want to find out whether it's located somewhere within the arms of the hyperbola, that is at position number a or whether it's located on the hyperbola or whether it's located outside the arms of the hyperbola. Now guys, in case of a hyperbola, the situation is slightly different. If the point is at a, then if you substitute a in place of x and y for this hyperbola, you realize that x1 square by a square minus y1 square by b square is actually greater than 1. That is x square by a square minus y square by b square minus 1 will be positive. If it is a situation number b, then you would realize x1 square by a square minus y1 square by b square minus 1 will be equal to 0. And if it is at position number c, x square by a square minus y square by b square minus 1 would be less than 0. Again, this expression is called s. x square by a square minus y square by b square minus 1, this is called s. And when you put the point in place of x and y, this is called s1. So this is like saying s1 is greater than 0. This is like saying s1 is equal to 0 and this is like saying s1 is less than 0. So it is inside if it is greater than 0, on if it is equal to 0 and outside if it is less than 0.
