We recommend that certain principles guide any work to define a framework for Web services semantics. Our work is guided by the following principles. ? Build on existing Web Services standards: The Web services standards are fast becoming a preferred technology for application integration because of the promise of their interoperability. Companies are making investments in integration projects based on Web Services. Therefore, we believe that any approach to adding semantics to Web Services should be specified in an upwardly compatible

Introduction The Web Services Description Language (WSDL) specifies a way to describe the abstract functionalities of a service and concretely how and where to invoke it. The WSDL 2.0 specification does not include semantics in the description of Web services. Therefore, two services can have similar descriptions while meaning totally different things. Resolving this ambiguity in Web services descriptions is an important step toward automating the discovery and composition of Web services — a key productivity enabler in many domains including

Abstract This document defines a set of extension attributes for the Web Services Description Language and XML Schema definition language that allows description of additional semantics of WSDL components. The specification defines how semantic annotation is accomplished using references to semantic models, e.g. ontologies. Semantic Annotations for WSDL and XML Schema (SAWSDL) does not specify a language for representing the semantic models. Instead it provides mechanisms by which concepts from the semantic models, typically defined outside the WSDL

The Semantic Annotations for Web Services Description Language (SAWSDL) Working Group released a Last Call Working Draft of Semantic Annotations for WSDL . Semantic annotations can be added to Web Services Description Language (WSDL) components for use in classifying, discovering, matching, composing, and invoking Web services. Comments are welcome through 1 November. The group also released the First Public Working Draft of the companion Usage Guide . Semantic Annotations for WSDL (SAWSDL) defines how to add semantic annotations to various parts
