Mike -
I agree. The current model, while clearly understood by many, I believe is
being interpreted in slightly different ways, enough so, to be causing all
the confusion and concern you mentiono. I still believe a very high level
diagram of the relationships between the client - consumer - producer would
be extremely beneficial. I am not sure how to draw that, as each
conference call, the diagram I draw is different from the one before. So
for me, to get this all straight, I quess it comes down to definitions.
And from those definitions we can determine relationships, etc. So, I took
the liberty of using some of the statements that you made in your email, to
see if they are agreed upon or not. This will also be helping for the
definitions in the glossary. So here goes:
client = an end user
[CL] ok [CL]
consumer = an intemediary responsible for the aggregation and control of
heterogeneous producer services, responsible for the interaction between
the client and the producer services placed on the clients application
interface.
[CL] ok [CL]
producer = a container of producer services
[CL] ok [CL]
producer service = the WSIA/WSRP compliant service ( aka. portlet )
[CL] ok [CL]
template = a producer service, with initial settings specified
[CL] template = design time instance of a portlet. [CL]
entity = an instance of a producer service ( potentially based on a
template )
[CL]instance = logic with some associated data (persistent or transient)
[CL]
transient entity = an instance of a producer service
[CL]ok [CL]
persistent entity = an instance of a producer service + persistent data
[CL]ok [CL]
session scope = is a shared scope between all entities within a producer
that a consumer chooses to group together. This can be all the entities of
the producer, a subset of entities, and even at the extreme one session per
entity.
[CL]ok [CL]
While, I know some of the definitions are terse, I am trying to see if the
relationships are correct. Because half the battle during these
discussions is trying to understand what everyone is saying, especially
when we are all working off of various interpretations of what the terms
actually mean. So, please, let me know, where my interpretation is wrong,
and hopefully from these definitions, the relationships will be evident,
and our efforts can proceed.
