During this period, the pattern catalog underwent exhaustive reviews by SOA experts and practitioners, key members of the patterns community, as well as members of the vendor and academic communities. Additionally, an open public review of the first draft of the manuscript of this book was held for several months at SOAPatterns.org during which over 200 individual reviews were collected. The History and Acknowledgements pages provide further details regarding past review stages and cycles. The feedback collected as a result of this review process helped validate many patterns, but also helped identify those that were either invalid or not yet ready to be considered fully proven or field-tested. Because these patterns were not considered ready for inclusion in the official SOA design pattern catalog they were classified as candidate patterns. This inspired the idea to create a forum in which proposed patterns could be published and subjected to open community review and feedback on an on-going basis. A primary goal of SOAPatterns.org is to help foster the development of new patterns in order to continually evolve and expand the master SOA design patterns catalog. In support of this goal, you are encouraged to get involved by: • Reviewing and providing feedback about published candidate patterns. You can do this by visiting the Candidate Pattern List page. • Contributing your own candidate patterns using the Candidate Pattern Contribution Form. Note that it is recommended that you first carefully review the existing candidate patterns before submitting your own to avoid potential duplication.
