WS-specification: Specifying web services using UDDI improvements

Abstract

Web services are interoperable components that can be used in application-integration and component-based application development. In so doing, the appropriate specification of Web services, as the basis for discovery and configuration, becomes a critical success factor. This paper analyses the UDDI specification framework, which is part of the emerging Web service architecture, and proposes a variety of improvements referring both to the provided information and the appropriate formal notations. This leads to a more sophisticated specification framework that is called WS-Specification and provides information referring to different perspectives on Web services. It considers Web service acquisition, architecture, security, performance, conceptual concepts and processes, interface definitions, assertions, and method coordination. WS-Specification thereby maintains backward-compatibility to UDDI and is ordered using a thematic grouping that consists of white, yellow, blue, and green pages. © Springer-Verlag Berlin Heidelberg 2003.
