Similarities/Differences in RA Goals and Requirements and WSA Goals and Requirements

[Danny Thornton <danny_thornton2@yahoo.com>]

There are 7 goals defined for the Web Services
Architecture (WSA):

http://www.w3.org/TR/2004/NOTE-wsa-reqs-20040211/#id2605249

The WSA goals are Interoperability, Reliability,
Integration with the World Wide Web, Security,
Scalability and Extensibility, Team Goals, and
Management and Provisioning.

The initial list of topics for the SOA RA include
interoperability, life cycle, standards, policy,
management, security, realization, capabilities,
discovery, interaction, service composition,
configuration (part of management), resources,
description, information model, management of meta
data, versioning, deployment.  

The SOA RA has more depth than the WSA in the number
of building blocks required for cross domain,
interoperable, manageable, secure services.  However,
many of the WSA critical success factors and
requirements are generic enough that they could be
ported straight into an SOA RA.  For example, the WSA
security requirements are generic enough that they
could also be requirements for a SOA RA.  

One way to capture this relationship is to make the
WSA a related model to the SOA RA.  On the Wiki, we
could make direct links to the WSA web page where
there is overlap.
