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

Title: Message

But in the latest proposal, there's no way for the Consumer to know which 
model the Producer uses, so it doesn't know whether to use a single session or 
to use multiple sessions.

Eilon - what part of the spec says that there was "THE 
  session". The spec 
allows for creating an arbitray 
  number of sessions, already covers the 
general 
  approach.

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.

      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). 
            
  -Mike-

  Carsten and team,Attached are some additional thoughts on 
      sessions - 
            in 
  particular how people may want to use sessions in a 
      different way 
            that 
  I am not sure works very well with our current

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