I apologize for having missed the call. I messed up the start time by 
one hour. Some comments to the minutes:

>Ellen expresses her preference for the "three-bubble-diagram"

I understand that the new diagram can be too complex for the purpose of the section.
Coming back to my original OGF comments, the main issue was if we should state, by design, that 
"advertised capabilities and activity requirements all rely on the same resource description" (maybe optional for the managed instances model).
This seems to be the way OGF is taking by dropping the JSDL attributes for resource requirements and by moving to XQuery expression against resource representation.

If we agree on this, a new proposal for the diagram that maintains the simplicity but that shows this assumption is attached


>The group agrees that the UML diagram should not be discarded, but

>Ellen recommends to use Sergio's UML diagram in the same document,
>for example in chapter 5 or the appendix.

ok, I will work on this

the current rendering is aligned with the current GLUE Spec. We can work on adding examples of representation of resources and XQuery/XPath expressions



Cheers, Sergio
