"Extensible Messaging and Presence Protocol (XMPP): Core", Peter Saint-Andre, 1-Jun-09. ( bytes): This document defines the core features of the Extensible Messaging and Presence Protocol (XMPP), a technology for streaming Extensible Markup Language (XML) elements for the purpose of exchanging structured information in close to real time between any two or more network-aware entities. XMPP provides a generalized, extensible framework for incrementally exchanging XML data, upon which a variety of applications can be built. The framework includes methods for stream setup and teardown, channel encryption, authentication of a client to a server and of one server to another server, and primitives for push-style messages, publication of network availability information ("presence"), and request-response interactions. This document also specifies the format for XMPP addresses, which are fully internationalizable. This document obsoletes RFC 3920.
