Re: [soa-rm-ra] Topic for Thought - Choreography and Relationship to OASIS SOA RM Service Description

[Ken Laskey <klaskey@mitre.org>]

I think this makes a lot of sense.  As I understand it, a choreography would specify the actions that needs to be taken and one's response when others have already completed certain actions.  It needs to be consistent with the process models of services participating in the choreography.  So if my process model says you need to have established a valid login before I send you information, the choreography should tell you to start by logging in, or at least check to see if a login is necessary.

Reading and understanding more on choreography is a major item on my to-do list.

I saw an interesting take on Choreography and its

relationship to the OASIS SOA RM.  Choreography was

mapped to the Service Description's Process Model

based on what someone read in a Q&A session with Steve

Ross-Talbot, the co-chair of the W3C Web Services

Choreography working group.

I initially did not associate choreography with the

atomic service, but after reading the Q&A I like the

association of choreography with the Service

Description's Process Model. The Process Model is the

dance steps (choreagraphy) that an individual service

makes in an overall orchestration of services.

Other thoughts on this?
