SOA and Web Services Standards

In addition to first-generation standards (WSDL, SOAP, UDDI), there are many second-generation standards that address security, trust, and other issues. The following document from IBM provides links as well as brief summaries of the various standards from W3C, OASIS, WS-I, and other organizations. SOA and Web Services Standards
