The Open Group SOA Source Book is a collection of source material for use by enterprise architects working with Service-Oriented Architecture.

It consists of material that has been considered and in part developed by The Open Group SOA Work Group. The SOA Work Group is engaged in a work program to produce definitions, analyses, recommendations, reference models, and standards to assist business and information technology professionals within and outside of The Open Group to understand and adopt SOA.

The Source Book includes the final output of that work program, which is also published separately as a collection of Open Group Standards and Guides. It also includes interim material, reflecting the current state of work that has not yet resulted in formal Standards and Guides. The content of this material will not necessarily be reflected in the final output.

This is Edition 4 of the SOA Source Book. Edition 1, published by Van Haren in April 2009, and also available on the web, contained interim material only. Since it appeared, The Open Group has published three SOA standards and one SOA guide – The Open Group Service Integration Maturity Model (OSIMM), The Open Group SOA Governance Framework, The Open Group SOA Ontology, and the Guide to Using TOGAF to Define and Govern SOAs – and has also published a White Paper on Navigating the SOA Open Standards Landscape around Architecture, which was written by the Work Group together with members of OASIS and the OMG. The first two of the standards and the White Paper were summarized in the body of Edition 2, and included in full as appendices. Edition 2 also included updated interim material on Service-Oriented Infrastructure. Edition 3 added the SOA Ontology, which was approved as an Open Group Technical Standard in October 2010. Edition 4 adds the Guide to Using TOGAF to Define and Govern SOAs, and has a new structure, with the Standards and Guides now appearing in the body of the Source Book, rather than as appendices.

The material in the SOA Source Book reflects input from a large number of people from a wide range of Open Group member companies, including product vendors, consultancies, and users of SOA. In some cases, these people have brought concepts developed, not just by themselves, but by groups of people within their organizations. The input has been refined and further developed through discussion within the Work Group. The value in the result is due to the ideas and efforts of the Work Group members.

The material is now published in its current form to make that value available to the wider architecture community.
