  1. SOAP, UDDI, Web Services, andthe Semantic Web Justin R. Erenkrantz ICS 221 December 3rd, 2002

  2. Web Services • Identified by URI, HTTP, and XML • Making websites more than content • Enabling extensible interactions • Ideally public, perhaps private • Commercial web services

  3. SOAP • W3C’s Simple Object Access Protocol • XML-centric middleware data format • Origins from simpler XML-RPC • Nodes, roles, faults • Typically bound to HTTP • Interesting architectural mismatches

  4. UDDI • Universal Description Discovery and Integration • Acts as a naming service for Web Services • Built on top of SOAP • Distributed repositories • Publish/subscribe support • SOAP callbacks

  5. Semantic Web • “Crown Jewel” • Meaningful interpretation of web content • Not just interactions, but understanding • Each semantic web site agrees on meaning • Effects of non-participation
