The BioCASE Provider Software (BPS), an xml data binding
middleware, is used as an abstraction layer in front of a
database. After local configuration the database is accessible
as a BioCASE service - as defined by the BioCASE protocol - and
can be used to create distributed heterogenous information
systems. The BPS is agnostic to the kind of data being exchanged
and any conceptual schema, such as ABCD for the BioCASE network,
can be used to set up distributed networks.  The provider
software is a collection of tools to be installed on the data
provider's webserver. The core part of the provider software is
the PyWrapper software. It is an XML/CGI database interface
written in object-oriented Python, which allows a standard
access to a variety of database management systems and

"wraps" the database into a standard XML format. Since version
2.0 the core PyWrapper libraries are bundled with this package.
