RE: [soa-rm-ra] OASIS SCA TC Relationship to the OASIS SOA RA SC

["John, Anil" <Anil.John@jhuapl.edu>]

For a rather good introduction to SCA, because implementers/vendors in
the space will naturally emphasize one particular aspect over another,
check out the following white paper from David Chappell:

Introducing SCA

Blog entry about the above:

> 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.
