 | Level: Introductory Contributors: Hewlett-Packard Company, IBM, Intel Corporation, Microsoft Corporation 23 May 2007 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.
