12:05	Review of F2F agenda / property description metadata - Charlie

Reviewed F2F agenda - Monday focusing on customization and metadata for
properties. Aiming to also bring Coordinated Use Case into that discussion
(single producer, cross-entity). 

Have been progressing property management in the Customized Use Case,
looking to use the "model" side of XForms to do this.

Still trying to get WSRP / WSIA alignment on the property interfaces at the
entity level. It popped up as a todo at the last F2F, so trying to get it
squared away before this next one. Customized is focused on entity-based
scenarios around properties, and have a proposal for a way for a Portal
Administrator to use that same mechanism. That's not been reviewed within
WSRP yet. Might be possible to use that same mechanism for the session
properties.

Alan elaborated a Use Case suggesting how the session-based properties might
be relevant to WSRP scenarios. viz, Where the portal vendor is a fat
consumer, modeling and mapping entities with a hierarchical preference set,
not wishing to force that property management on a producer. ie, No need for
the producer to know about entity relationships that the consumer has. So
the conversation with the producer would just be for the session level
properties.

This brings up the question of understanding what is the core need of WSRP.
Moving to the session level would imply thinner producers.

Separately, but related - object model discussion. Can we promote the
session as a narrowing of the entity? The two are treated separately today
with different operations and args. Need to pursue a discussion of whether
it makes sense to hide one behind the other. Pragmatically, is it too late
for this, causing too much disruption, or is it just the right thing to do?

Alternative way of stating / implementing this - We're talking about the
entity as being a specialized session state, so the user session starts as
an entiry and evolves at runtime. The entity "clone" does some work and goes
away.

(Not looking to address or change shared session or lifecycle semantics with
this).

action: Charlie - to write up this use case and circulate it.



12:40	Review of Customized - Tim

Reviewed the doc sent out to the list on 8/14. Reviewed XForms usage for
property descriptions, showing separation of schema/model info, and instance
data. [Nice :-) - Ed. ]

Unanswered question - should setting property on session bubble through to
the entity? Needs discussion, and sounds related to the earlier debate.




1:00	out of time - adjourn.
