IBM WebSphere Service Registry and Repository (WSRR) provides service registry and repository functions for service-oriented architecture (SOA) enterprise applications. This IBM Redbook publication uses business scenarios to illustrate SOA governance using WSRR as the authoritative registry and repository. In part one of this book, we introduce SOA and service governance, provide a technical overview of WSRR, and describe the WSRR governance enablement profile. Part two of this publication provides step-by-step guidance to building WSRR solutions. This part addresses topics such as modeling in WSRR Studio, creating a WSRR user interface, security, promotion, policies, and reports. Part three describes a series of common usage scenarios and describes step-by-step how to implement them in WSRR. These scenarios describe how to govern schemas, existing services, new services, upgrades to services, and business processes. This Redbook is based on WebSphere Service Registry and Repository V6.3. <u>Related publications:</u> <a href="http://www.redbooks.ibm.com/abstracts/sg247782.html">IBM Redbooks publication: Service Lifecycle Governance with IBM WebSphere Service Registry and Repository Advanced Lifecycle Edition</a> <a href="http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbstracts/redp4557.html">IBM Redpaper: Integrating WebSphere Service Registry and Repository with WebSphere Process Server and WebSphere ESB</a> <a href="http://www.redbooks.ibm.com/Redbooks.nsf/RedpieceAbs

The IBM® System z® platform is the strategic core of business world wide. By using a realistic customer scenario, two IBM teams ventured to demonstrate how to deploy the IBM service-oriented architecture (SOA) portfolio on IBM z/OS® and on z/OS in partnership with additional platforms such as AIX® and Linux® for System z. The teams created the experience that is documented in this IBM Redbooks® publication to explain the work that is required to create, deploy, and test the SOA solution on both z/OS and z/OS with additional platforms. The teams also performed extensive testing to verify the correct behavior of the platforms, products, and applications involved. This Redbooks publication covers the product configuration that is necessary to build the SOA solution described in the project scenario. This book provides useful hints and tips that were discovered during the course of testing to ensure successful solution deployment. It also provides an extensive set of references to other documents that proved useful for building the solution. This book is designed for IT professionals who are interested in creating an SOA solution either entirely on z/OS or on z/OS in conjunction with other platforms. Prior to reading this book, you must have basic knowledge of SOA solutions, z/OS or other platforms, and the SOA products running on those platforms.

Service-oriented architecture offers the promise of business agility and resilience through reuse, loose coupling, flexibility, interoperability, integration and governance. These are realized by separating service descriptions from their implementations, and using this descriptive metadata across the service lifecycle. Standards-based service metadata artefacts, such as Web Service Description Language, XML schema, policy or Service Component Architecture documents, capture the technical details of what a service can do, how it can be invoked, or what it expects other services to do. Semantic annotations and other metadata can be associated with these artefacts to offer insight to potential users of the service about how and when it can be used, and what purposes it serves. IBM WebSphere Service Registry and Repository (WSRR) is the master metadata repository for service interaction endpoint descriptions. As the integration point of service metadata, WSRR establishes a central point for finding and managing service metadata. Once service metadata is placed in WSRR, visibility is controlled, versions are managed, proposed changes are analyzed and communicated, and usage is monitored. This IBM Redbook discusses the architecture and functions of IBM WebSphere Service Registry and Repository along with sample integration scenarios that can be used as examples for implementing WebSphere Service Registry and Repository in a customer service-oriented architecture environment.
