Subject: RE: [wsrp] [wsia] [wsrp-wsia joint interfaces] agenda for Tuesday 11June
Gil -
1-3: the consumer MUST explicitly create entities (transient or
persistent). It can decide to create sessions explicitly if it wants to
share them amongs entities, otherwise it can let the producer create
sessions on the fly.
4: the decision to have multiple entities per session is up to the consumer
who make this choice based on the producer's metadata. e.g think of
portlets that form a shop together. These would want to share a session
with each other. But the consumer could decide to have two shops of the
same type on the same page. Then there would be two sessions and only the
consumer could know what portlet shares what session.
5: The consumer should create a session before issuing a getFragment call.
The entity is created whenever necessary.
6: A Session is a bucket that holds some data (physically on the provider)
and times-out after a while. A transient entity is a remote portlet that
does not store any data in a DB.
Hope that helped.
Best regards

Carsten, could you clarify some things for me?
1. If sessions and entities are orthogonal, what SHOULD the Consumer do?
2. SHOULD it create a transient entity _and_ a session?
3. MUST it do so?
4. Who gets to decide whether there are multiple entities per session or
multiple sessions per entities?
5. When SHOULD a Consumer create a session and when a transient entity?
6. What _is_ a session, logically? What _is_ a transient entity?
Gil

Alan - some first thoughts
1. the general concept is that entities (transient or persistent) and
sessions are orthogonal. There might be mulitple entities per session and
(at least for persistent entities) multiple sessions per entity. An example
for the first case would be that entities share session data within the
same user request. An example for the second case are portlets on a common
page (group page) that are access simultaneously by multiple users.
A transient entity differs from a persistent entity in that its data does
not persist and its lifecycle is coupled with the session life cycle.
2. Eilon pointed out in a comment to the interface proposal that batch
processing is already part of SOAP. I was not aware of that and will look
it up until the call.

I think we'll have plenty of discussion around the merged document Rich and
Carsten put together.
The two main issues I see that have arisen on the email lists are:
1. What is the difference between transient entities and sessions, and is
there enough of a distinction to warrant including both in the
specification?
2. There are efficiency concerns around the use of arrays in the method
signatures, basically to enable batched requests for network efficiency.
