SOAP

The Simple Object Access Protocol (see Section [*]) represents one of the fundamental technologies constitutive of this project. The SOAP 1.1 recommendations cover three different topics.
  1. a message encapsulation mechanism
  2. a data representation scheme
  3. a Remote Procedure Call (RPC) mapping to the HTTP protocol
The prototype built during this project (code-named XMLbroker) addresses all three areas. The limited scale of this project however means that the standard will only be implemented up to the degree of functionality necessary to provide a qualitative appreciation of the technology. A demonstration application--exposing a Network Time Protocol (NTP) server as a Web service, will support our discussion in Section A. We review below the main elements of the SOAP recommendations.
