SOAP is a protocol for exchanging information. W3C

Status

The SOAP 1.2 specification (formerly the Simple Object Access Protocol) became a W3C Recommendation in June 2003. SOAP 1.2 Part 0: Primer is published at http://www.w3.org/TR/soap12-part0/, SOAP 1.2 Part 1: Messaging Framework is published at http://www.w3.org/TR/soap12-part1/, and SOAP 1.2 Part 2: Adjuncts is published at http://www.w3.org/TR/soap12-part2/. SOAP Version 1.2 Specification Assertions and Test Collection, also a Recommendation, is published at http://www.w3.org/TR/soap12-testcollection.

Description

SOAP is an XML-based protocol for exchanging information in a decentralized, distributed environment. It consists of three parts : an envelope that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined data types, and a convention for representing remote procedure calls and responses.

More recently, a number of RDF Working Drafts revising those specs have been published. Resource Description Framework (RDF): Concepts and Abstract Syntax is published at http://www.w3.org/TR/rdf-concepts/. RDF Semantics is published at http://www.w3.org/TR/rdf-mt/.

RDF/XML Syntax Specification (Revised) is published at http://www.w3.org/TR/rdf-syntax-grammar.
