Subject: OASIS SCA TC Relationship to the OASIS SOA RA SC
Hi All, A little info from the SCA Meeting being held in Palo Alto, CA today. The OASIS SCA TCs are focused on standardizing declaritive deployment specifications for components within an SOA-based enterprse. If you are familiar with J2EE, SCA is declaring service and service composition XML deployment descriptors in an EJB fashion. During the meeting introduction, it was stated that the SCA TCs would like to coordinate with the OASIS SOA RM, OASIS SDD, Management-WSDM-SML, and WS-* standards. The SCA efforts started in Jan 06 as Open CSA and currently have wide vendor support. Today is the kick-off for the SCA TCs. The SCA TCs are addressing implementation details so they appropriately do not address topics that are covered in the Business via Services view of the RA. The OASIS SOA RA Interaction Model is very similar to a SCA presentation given today on understanding the core of SCA. While SCA defines a composition of services within an enterprise or even across enterprises (by reference), it is not an orchestration and does not define the temporal relationships between the services. It is meant to address the deployment properties of offered services by an enterprise. I think an SCA descriptor could be a governance artifact within the registry/repository - should we create a meta-model for governance like we have for Service Descriptions? Other sections of the RA that are complimentary to SCA are Visibility, Policies and Contracts, Security, and Management. I see the SCA TC activities and the SOA RA SC activities being complimentary and not conflicting.
