Written in conjunction with members of The Open Group's SOA Work Group by Dr. Chris Harding, forum director of the SOA Work Group, the book offers a pragmatic approach for creating service-oriented enterprise architectures based on industry best practices. The first edition, published in April 2009, was derived from SOA Work Group projects during 2008. The second edition will include results of the group's work in 2009.

The Open Group published two major SOA standards during 2009: the Service Integration Maturity Model and the SOA Governance Framework. The Open Group also collaborated with members of the Organisation for the Advancement of Structured Information Standards (OASIS) and the Object Management Group (OMG) to publish a whitepaper explaining the open SOA standards produced by the three organisations and describing how they relate to each other.

The new edition of the SOA Source Book includes these publications in full, together with material updated from the first edition on SOA and enterprise architecture, SOA and TOGAF™, The Open Group SOA Reference Architecture and service-oriented infrastructure.

In addition, the SOA Work Group is continuing to develop several resources, including the SOA Reference Architecture, Practical Guide to using TOGAF for SOA, Service-Oriented Infrastructure Framework, a Guide to SOA Security and a Guide to Legacy Evolution to SOA. This ongoing work will be incorporated in the Source Book over time, further increasing the value of the SOA Source Book as a major body of free-to-use reference material for SOA.

"With the release of the second edition of our SOA Source Book, we hope to continue to serve as an open and accessible resource for enterprise architects to help their organisations generate business value from SOA", says Dr. Chris Harding, forum director, SOA Work Group, The Open Group.


"We believe that the concepts and models developed through the Work Group's meetings and discussions will significantly benefit the industry, particularly as enterprise architecture evolves to address the advent of cloud computing."
