The Open Group gratefully acknowledges the following people in contributing, either directly or indirectly, to the SOA Source Book.

The material in the book is derived from the work of the Definition of SOA, SOA Reference Architecture, SOA/TOGAF Practical Guide, SOA Governance, Service-Oriented Infrastructure, and SOA Ontology projects of The Open Group SOA Working Group, from work done by The Open Group Service Integration Maturity Model project, and also from work done jointly by the SOA Working Group and the Semantic Interoperability Working Group.

The co-chairs of the SOA Working Group, Tony Carrato (IBM) and Mats Gejnevall (Capgemini), together with former co-chair Chris Greenslade (CLARS), member Jorge Diaz (IBM), and Forum Director Chris Harding (The Open Group), comprise the Working Group's Steering Committee. They are responsible for the overall direction of the Working Group and contribute greatly to the quality of its work. In addition, Tony Carrato took a particular interest in guiding the development of the Source Book. Chris Harding was primary author.

The Definition of SOA project was led by Dave Hornford (Hornford Associates).

The SOA Reference Architecture project is led by Ali Arsanjani (IBM) and Nikhil Kumar (ApTSi). Ali Arsanjani made a particular contribution in providing the base document for the work, having led its development within IBM.

The SOA/TOGAF Practical Guide project is led currently by Awel Dico (Bank of Montreal) and Dave Hornford, and was led formerly also by Steve Bennett (BEA Systems).

The SOA Governance project is led currently by Mats Gejnevall and Jorge Diaz, and was led formerly also by Andrew Hately (IBM), Tony Carrato, and Steve Bennett. In addition, Bill Brown (IBM) provided a substantial part of its base material.

The Service-Oriented Infrastructure project is led currently by Hemesh Yadav (Wachovia), E.G. Nadhan (HP), and Michael Salsburg (Unisys), and was led formerly also by Mark England (HP) and Frank Kroon (formerly Capgemini, now HP). E.G. Nadhan authored the Service-Oriented Infrastructure section of the Source Book.

The SOA Ontology project is led by Chris Harding.

The Open Group Service Integration Maturity Model project is led by Andras Szakal (IBM). He was responsible for providing the project's base document, which resulted from work led by Ali Arsanjani within IBM.

The contribution of the Semantic Interoperability Working Group was led by Arnold Van Overeem (CapGemini) and Ron Schuldt (Lockheed Martin).

Many of the people mentioned above also made contributions to projects of which they were not officers.

The following Working Group members, who were not project or working group officers, made particular contributions to one or more projects: Stuart Boardman (CGI), Kathy Carusone (MIT Lincoln Laboratory), Dave Chapelle (BEA Systems), Bill Estrem (Metaplexity), Ed Harrington (Model-Driven Solutions), Harry Hendrickx (Capgemini), Heather Kreger (IBM), Bob Laird (IBM), Srikanth Inaganti (Wipro), Shreyas Kamat (Infosys), Rich Valentine (Unisys), and Bobbi Young (Unisys).

Finally, over 300 other people have been involved in the SOA Working Group. It is not possible to mention them all individually, but their collective contribution is important.
