The World Wide Web Consortium (W3C) said it has published the Simple Object Access Protocol (SOAP) version 1.2 as a formal standard. SOAP is one of a handful of standards behind the industry move toward building Web services software. The protocol originated several years ago as an informational document within the Internet Engineering Task Force (IETF), another standards group, as a way of executing so-called remote procedure calls. Microsoft then jump-started work on the protocol as a way of letting business software applications communicate over the Web, regardless of what programming language they're written in.
