The Web Services Resource Catalog (WS-RC) specification describes an XML document format that supports the description of resources and services and their associated metadata in a model-neutral manner. This information allows for classification, linking, discovery, and access to relevant resources. Applications that need to discover resources and services can use a service that offers this catalog information via Web or Web services protocols.
In March 2006, HP, IBM®, Intel®, and Microsoft® announced plans to address customers' concerns around competing management specifications. This roadmap provided a high-level overview of the strategy being used to achieve the goal of having a single set of specifications for resource access and manipulation, events, and management. As the work progresses, specifications are continuously being made available for public review and feedback. The second of these specifications is WS-ResourceCatalog (WS-RC).
WS-RC addresses the requirements satisfied by WS-ServiceGroups, aspects of WS-ResourceMetadata, Web Services Distributed Management (WSDM), and the WS-Management Catalog. WS-RC defines only the schema of a catalog. When used in conjunction with other Web service specifications for data access and manipulation (such as HTTP, WS-ResourceTransfer, or WS-ResourceFramework), it provides the foundation for an interoperable mechanism to locate and advertise resources for the current management stacks of WSDM and WS-Management, as well as the converged management stacks.
The authors are committed to providing this work as the base for the next generation of standardization for Web services and management. Consistent with previous roadmap efforts, the development, interoperability testing, and standardization process takes time, and they welcome the feedback from the Web services community.
Customers and vendors should continue investing in solutions and products based on the implementations of the current specifications related to this work (WS-ResourceFramework and WSDM). The vendors are assuring that this convergence of the competing specifications will be a smooth evolution from today's environment and provide a simplified technology base for the future. As the new specifications are finalized, a clear migration path will be defined in IBM's WDSM/WS-Man Reconciliation – An Overview and Migration white paper.
