SOAP: Simple Object Access Protocol

SOAP: Simple Object Access Protocol. Dynamically generated HTML content works fine in Web browsers, but it presents a nightmare for anyone trying to utilize that data with other programs. For example, you can easily view an auction site in a browser, but an application would require a complex HTML parser to read your bid's status from the same site. Worse, you would need a different parser to track a different auction site, and the simplest redesign of either site could throw off your program.

Web services solve this problem with a consistent and easy method for accessing online information. Web services could potentially create a whole new type of Web.

A protocol created by Microsoft, DevelopMentor, and Userland Software and backed by companies that include IBM, Lotus, and Compaq gives a big push toward that vision. Simple Object Access Protocol (SOAP) exchanges application data over HTTP in XML encoding.
