Notes for Discussion Proposal Issue 30 CPPA Service and Action
Tuesday, November 20, 2001 
Updated on Monday, November 26, 2001
Describe the main issue 
Arvola Chan, Hima Mukkamala
MS team says Service Element in Message Header will come from Service
Element in CPA and Action in Message header comes from CPA.
How are Service and Action derived from BPSS? Need unique Service and
Action. Role(s). 
Discussion and ideas
Arvola Chan, Hima Mukkamala, Brian Hayes, Dale Mobray
Service = BPSS Unique Process Identifier (UUID)

Request to make UUID a URN, (see the business process worksheet document)

Service, in combination with CPAid (from the message header) provide further
discrimination for application routing

Action = Process Specification Name + Binary Collaboration Name + [Nested
binary collaboration Collaboration Activity Name(s)] + Business Transaction
Activity Name + Requesting or Responding Activity Name

The [Collaboration Activity Name(s)] are only needed when there are nested
Collaboration Activities. When there are multiple nested Collaboration
Activities, there will be multiple Collaboration Activity Names in the
Action.

Short version and long version of action value in CPA.

Make Activity Name required and unique.

Use xpath semantics to uniquely identify the requesting business activity
and responding business activity. [Maybe, maybe not.]

For the action names to be asymmetric, the BPSS Requesting Business Activity
and Responding Business Activity need to be made required.
