[bt-spec] Relationship: Composer:Participant

[Sanjay Dalal <sanjay@bea.com>]

There seems to be an issue regarding relationship between Composer and Participant. I am attaching relevant discussion on mailing list. I am told that it was discussed in LC f2f but no conclusion was made. I am sending this formal request to open an issue on this topic to track it and close it.

 

thanks,

sanjay

Sanjay,

Sorry I didn't comment on your diagrams earlier - I think they will be really helpful, and some at least will get into the intended model section.

thanks. I hope these are also useful for primer apart from the specifications.

[sanjay] What is the relationship between Composer and Coordinator?

[peter] Composer and Coordinator have direct S:I relation to sub-coordinator, to sub-composer and to participant

[sanjay] Sazi tells me that this was not resolved in f2f, esp. Composer-Participant and Composer-Sub-composer relationships. I understand your thinking too. I have kept the relationships at abstract level i.e. one can implement such that the same entity can play the roles of Composer and Coordinator. It means, that entity can directly talk to the Participant. In the same way Sub-coordinator and Sub-composer can be played by another entity. That way Composer-Coordinator entity can talk directly to Sub-composer-Sub-Coordinator entity.

 

[sazi] We have discussed the relationship between composer and participant at the f2f meeting. I have pointed out that Composer having a direct relationship to a participant is new in the current spec, and somehow invalidates the role of coordinator. Peter and I have given some examples of our understanding on this issue...

Although, I don't belive we have a final decision on the issue, it was an interesting discussion, we may be much closer to a final decision then it seems...
