Specific aircraft types, to be exact (e.g., Douglas DC-3). When describing a photograph (residing on the Web site) or a book (that can be physically bought), we'd like to be able classify the content specifically (e.g., this book is about the DC-3 but I am not sure how to say that -- so far that page only has very minimal structured data).\n> \n> We have a carefully curated in-house vocabulary of approx. 5000 aircraft types that we are thinking of using, but the question is \"how?\"... My current thinking is that if there was a base type we could extend that by ourselves. \"Aircraft\" could be a subclass of \"Vehicle\" (although that is a product and I am not sure what ramifications that has, e.g., if I talk about Boeing 787 as a product will the Boeing lawyers have a problem with that?). Rather than extending \"Aircraft\", we could make instances of \"Aircraft\" and use an external code (referring to our vocabulary) to indicate which aircraft type it is.\n> \n> Any thoughts?\n> \n> �\n> Reply to this email directly or view it on GitHub.\n> \n\n"}}
