Minutes Approval call Nov 29 and London F2F Agreed 2. Start with use cases document Sergio describes the example Donal: in GLUE is it explicit the association of users to shares? Sergio: yes, there is AccessPolicy for Endpoint and MappingPolicy for Shares Dave: I'm fine with the example, I would probably change share fast/slow to blue/green - Action: Sergio to change naming of shares - Action: Ellen to update Sect.4 with this example 3. Discuss XML representation Michel: what about having full XML in the appendix Andreas: compact XML where stuff not used in floating text, while full XML in appendix Sergio: to provide high-level diagram showing the GLUE concepts that are used to model the use case 4. Discuss queries Dave: include expected outcome of queries Andreas: ex.1 just lists the available shares, not select some share based on some requirements Michel: wanted to be simple in the first ex. - in Ex.2, multiple [] can be used to have AND behavior of multiple requirements on sibling nodes Dave: suggests to make AND explicit for easy of reading Michel: differences between ex.2 and ex.3 is the usage of variable; We can come up with a standard set of queries that can be reused instantiating different values for 5. Discuss real production scenario and how we can add to the document Sergio describes the use cases; it requires join. Michel prefers not to put too complex example queries After a discussion, we agree to: - add the example - Michel will add XPath snippets - Sergio to provide XQuery 6.
