SOAP version 1.2 is a lightweight protocol for exchange of information in a decentralized, distributed environment. It is an XML based protocol that consists of four parts: an envelope that defines a framework for describing what is in a message and how to process it, a transport binding framework for exchanging messages using an underlying protocol, a set of encoding rules for expressing instances of application-defined data types and a convention for representing remote procedure calls and responses. Part 1 describes the SOAP envelope and SOAP transport binding framework; Part 2 describes the SOAP encoding rules, the SOAP RPC convention and a concrete HTTP binding specification.
