Abstract
The Microsoft Global XML Web Services Architecture (GXA) initiative is a protocol framework designed to provide a consistent model for building infrastructure-level protocols for Web services and applications. In addition to this underlying protocol framework, GXA defines a family of pluggable infrastructure protocols that provide applications with commonly needed services such as security, reliability, and multi-party agreement. GXA provides a set of common facilities that are needed by a wide number of Web services and applications, built on the foundation of XML and SOAP. Some of the specifications released to date include: -- WS-Security - Provides a security language for Web services; enhances SOAP messaging with credential exchange, message integrity, and message confidentiality -- WS-Policy - A general-purpose specification describing how to express enterprise security policies -- WS-Routing - Describes mechanisms for routing SOAP messages without the need to rely on underlying transport mechanisms. -- WS-Transaction -- Adds transactional/coordination capabilities to Web services -- WS-Inspection -- Provides a means for flexible discovery of Web services, regardless of the mechanism used to describe them (WSDL, UDDI, etc.) This presentation will provide an overview, history, and future of the GXA initiative, as well as a brief overview of each specification that comprises GXA. |
