Dear all, I have further updated the OGSA 1.5 document to address the comments discussed on Thursday's telcon (see attachment). This is the version I have sent to Andreas (the editor). Further discussion about this document will take place on the Monday OGSA calls. One of the issues we discussed on Thursday was whether to keep separate sections on "architectural considerations" and "properties". I've renamed "architectural considerations" to "legacy considerations", because this better describes its content - I'm happy to consider better titles for this section. I've also reworded the introductions of both sections, and moved "transformations" back to the "functionality" section. Another issue we discussed was the relationship between metadata catalogues, data discovery, and the OGSA information services. I've attempted to clarify these by saying that OGSA information services provide the framework for data discovery, but that data discovery also requires languages or ontologies for describing data. For some use cases, we may want metadata catalogues with more limited functionality, e.g. just looking up the metadata associated with a particular abstract name.
