Subject: RE: [wsrp-interfaces] RE: [wsia] Sessions


Title: Message
Carsten,
 
I think where the confusion might lie is that the latest spec proposal uses the approach that you outlined below: the portlet developer segregates its information in the shared session. The other approach I outlined in the document suggest that the portlet developer may want to use a completely separate session per occurrence of a portlet. None of the approaches is necessarily better (I outlined some of the pros/cons in the document). However, we need to ensure that as we continue developing the spec, it will allow the portlet developer to choose between those two options.

Mike -
I agree with Eilon's conclusion to not enforce a maybe limiting session
sharing model in WSRP. If we allow the consumer to group portlets to
different sessions we have the best of the two worlds: if required portlets
can namespace data they do not want to share even if there is a shared
session. They either use a constant prefix or their entiy ID for this. Both
is possible without any modifications of the interface proposed in the
draft spec. Parameters they want to share are not prefixed at all or with a
prefix known to all participating portlets.

Best regards
Carsten Leue

Eilon,
   Can you elaborate on your conclusion that we shouldn't enforce a model?
I am not really sure how we can have our cake and eat it too.  Either our
model requires a key or its doesn't or its a hybrid that allows both.  I
would prefer not doing that later as it seems messy in the interface (and
complicates it).

            As promised (though a bit late) here is a sketch of my current
            understanding of the notion of sessions.
