In WS MDS, WebMDS is a web-based interface to WSRF resource property information that can be used as a user-friendly front-end to the Index Service or other WSRF services.

The WS-Addressing specification defines transport-neutral mechanisms to address web services and messages. Specifically, it defines XML elements to identify web service endpoints and to secure end-to-end endpoint identification in messages. See the W3C WS Addressing Working Group for details.

WSDL4J allows the creation, representation, and manipulation of WSDL documents. For more information, see http://www-136.ibm.com/developerworks/opensource.

WSDL is an XML document for describing Web services. Standardized binding conventions define how to use WSDL in conjunction with SOAP and other messaging substrates. WSDL interfaces can be compiled to generate proxy code that constructs messages and manages communications on behalf of the client application. The proxy automatically maps the XML message structures into native language objects that can be directly manipulated by the application. The proxy frees the developer from having to understand and manipulate XML. See the WSDL 1.1 specification for details.

The WS-I Basic Profile specification is a set of recommendations on how to use the different web services specifications such as SOAP, WSDL, etc. to maximize interoperability.

The WS-Notification family of specifications define a pattern-based approach to allowing Web services to disseminate information to one another. This framework comprises mechanisms for basic notification (WS-Notification), topic-based notification (WS-Topics), and brokered notification (WS-BrokeredNotification). See the OASIS Web Services Notification (WSN) TC for details.

Web Services Resource Framework (WSRF) is a specification that extends web services for grid applications by giving them the ability to retain state information while at the same time retaining statelessness (using resources). The combination of a web service and a resource is referred to as a WS-Resource. WSRF is a collection of different specifications that manage WS-Resources.

This framework comprises mechanisms to describe views on the state (WS-ResourceProperties), to support management of the state through properties associated with the Web service (WS-ResourceLifetime), to describe how these mechanisms are extensible to groups of Web services (WS-ServiceGroup), and to deal with faults (WS-BaseFaults).
