Working Drafts (Developer Discussion) ?Events/Pubs?Bookmarks

The goal of XML Protocol is to develop technologies which allow two or more peers to communicate in a distributed environment, using XML as its encapsulation language. Solutions developed by this activity allow a layered architecture on top of an extensible and simple messaging format, which provides robustness, simplicity, reusability and interoperability. The XML Protocol Activity Statement explains the W3C's work on this topic in more details.

The first working group in this activity is the XML Protocol Working Group.

The initial focus of theXML Protocol Working Group is to develop a framework for XML-based messaging systems, which includes specifying a message envelope format and a method for data serialization, directed mainly, but not exclusively, to RPC applications, and conforming with the abovementioned principles. More specifics are available from the Charter.
