The Ultimate Guide for Designing and Governing Web Service Contracts
For Web services to succeed as part of SOA, they require balanced, effective technical contracts that enable services to be evolved and repeatedly reused for years to come. Now, a team of industry experts presents the first end-to-end guide to designing and governing Web service contracts. Writing for developers, architects, governance specialists, and other IT professionals, the authors cover the following areas:
- Understanding Web Service Contract Technologies
- Fundamental and Advanced WSDL
- Fundamental and Advanced XML Schema
- Fundamental and Advanced WS-Policy
- Fundamental Message Design with SOAP
- Advanced Message Design with WS-Addressing
- Advanced Message Design with MTOM, and SwA
- Versioning Techniques and Strategies
- Web Service Contracts and SOA
