What is a Web Service?  web services replace traditional APIs  unlike traditional APIs, which lock users into a specific object model and language interface, web services are interfaces supported by all major enterprise architectures (J2EE, MS, IBM, BEA)  in many web service implementations, the following interface standards apply  the shared object model becomes SOAP (Simple Object Access Protocol)  PKI is abstracted using SAML (Security Assertion Markup Language)  each of these are XML text messages across an anonymous or secure socket connection on TCP/IP IT Standing Committee Meeting September 09, 2003

What does this mean to the Market?  IMO is developing the internal capability to deploy and support web services for the marketplace  web services will be deployed if and when future projects are defined and approved  benefits:  will lower the implementation cost and time for market participants relative to traditional APIs  market participant need not apply design, programming and support skills that are the same as the IMO and which may be foreign to their internal architectures and staff  APIs become standard compared to current deployed interfaces (MIM = Java/J2EE, IOMS = DCOM, MTR/NOD = Epic Workflow proprietary, etc.) IT Standing Committee Meeting September 09, 2003
