Subject: [wsrp][interfaces]: Agenda for 6/13 call
The following is the preliminary agenda for this Thursday's conference call. I may update/add to this later in the week. Agenda: We will continue discussing sessions. Two issues/discussions emerged from last weeks call that need to be completed: a) A model was discussed to support 2 types of session, explicit and implicit sessions. An explicit session is one that is (explicitly) established by the consumer. Its scope is defined by the consumer including 1 to N producer entities. An implicit session is established by a producer's entity in response to any request. Its scope is to just the entity that created/returned the session. Portlets must either run in an environment that uses explicit sessions or implicit session or no session at all. The various options can't be intermixed. There are two questions: first, should we allow producers to demand per entity sessions? If we do how should this "demand" be expressed? I.e. are implicit sessions the right way to model this? b) the question was raised as to how to support grouping entities into distinct sessions/namespaces within a given consumer. I.e. if we have two entity types (a topic portlet and a newsfeed portlet) that interoperate by sharing data, how do we support two groups of these portlets running in the same page? 2 options were discussed. In one option a single session was shared between the two groups and namespace/id was used to keep the data separate. In the other option, the producer (portlet service) defined a set of rules in its meta data that described the supported grouping that the consumer must provide for the producer. We need to discuss/resolve which option (or some other) to support.
