Summary:  When defining service life cycles with WebSphere® Service Registry and Repository, you can only use a single state machine definition. However, your organization may want two or more independent life cycles to govern different aspects of your services. This article describes how you can use Websphere Service Registry and Repository to support multiple life cycles within a single state machine definition.

Introduction

To help facilitate governance processes in an SOA, WebSphere Service Registry and Repository (hereafter called Service Registry) provides a simple mechanism for defining a life cycle that can be applied to services managed within it. Objects or related groups of objects stored in Service Registry can be transitioned through the states defined in the life cycle, and the resulting states will be reflected in the classification metadata associated with those objects. You can use the Service Registry console or APIs to locate and use the objects based upon these classifications.

Service Registry and Repository comes configured with a default service life cycle based on IBM's SOA governance model. However, most organizations will want to modify or replace this default life cycle with one that matches their exact requirements. The states and transitions of the Service Registry default life cycle are shown in Figure 1.
