OASIS SOA Reference Model Goes to Vote

The The OASIS Reference Model for Service Oriented Architecture v1.0 has been submitted for standardization by OASIS.

A reference model is an abstract framework for understanding significant relationships among the entities of some environment, and for the development of consistent standards or specifications supporting that environment. A reference model is based on a small number of unifying concepts and may be used as a basis for education and explaining standards to a non-specialist. [1] A reference model is not directly tied to any standards, technologies or other concrete implementation details, but it does seek to provide a common semantics that can be used unambiguously across and between different implementations.

A Reference Model is used by architects as a template for composing architectures. Much the same way as the auto industry agrees on the logical divisions in components of a car, the software industry uses reference models to make logical divisions and groupings within architectures. Doing so makes it easier for vendor products to be aligned to meet the requirements of the architecture and allows users to understand where their products fit into their corporate architecture. It works much the same way as when a tire manufacturer knows that an auto manufacturer understands implicitly that a "wheel" is a round component that bolts to a " hub" and accepts a " tire" into its rim. Unlike specific architectures, however, the reference model does not specify what size the wheel is or what bolt pattern it must use, only that it has those attributes. Individual instance of wheel and rim may vary in size, shape, and composition.

As such, this OASIS work provides an abstract template for definiing SOA projects. The document describes SOA as a paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains.
