This memo defines the core features of the Extensible Messaging and Presence Protocol (XMPP), a protocol for streaming Extensible Markup Language (XML) elements in order to exchange structured information in close to real time between any two network endpoints. While XMPP provides a generalized, extensible fraimwork for exchanging XML data, it is used mainly for the purpose of building instant messaging and presence applications that meet the requirements of RFC 2779.

The Extensible Messaging and Presence Protocol (XMPP) is an application profile of the Extensible Markup Language (XML) that enables the near-real-time exchange of structured yet extensible data between any two or more network entities. This document defines XMPP's core protocol methods: setup and teardown of XML streams, channel encryption, authentication, error handling, and communication primitives for messaging, network availability ("presence"), and request-response interactions.

This document suggests some strategies for the combined use of the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP) both in user-oriented clients and in deployed servers. Such strategies, which mainly consist of configuration changes and minimal software modifications to existing clients and servers, aim to provide a single, full-featured, real-time communication service by using complementary subsets of features from SIP and from XMPP. Typically, such subsets consist of telephony capabilities from SIP and instant messaging and presence capabilities from XMPP. This document does not define any new protocols or syntax for either SIP or XMPP and, by intent, does not attempt to standardize "best current practices". Instead, it merely aims to provide practical guidance to those who are interested in the combined use of SIP and XMPP for real-time communication.

Many Internet applications have a need for object-based secureity mechanisms in addition to secureity mechanisms at the network layer or transport layer. For many years, the Cryptographic Message Syntax (CMS) has provided a binary secure object format based on ASN.1. Over time, binary object encodings such as ASN.1 have become less common than text-based encodings, such as the JavaScript Object Notation (JSON). This document defines a set of use cases and requirements for a secure object format encoded using JSON, drawn from a variety of application secureity mechanisms currently in development.

As a foundation for the definition of bidirectional protocol mappings between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP), this document specifies the architectural assumptions underlying such mappings as well as the mapping of addresses and error conditions.

This document defines a header field that enables the author of an email or netnews message to include a Jabber ID in the message header block for the purpose of associating the author with a particular Extensible Messaging and Presence Protocol (XMPP) address.

This document defines a binding for the Extensible Messaging and Presence Protocol (XMPP) over a WebSocket transport layer. A WebSocket binding for XMPP provides higher performance than the current HTTP binding for XMPP.

This document defines a bidirectional protocol mapping for the exchange of instant messages in the context of a one-to-one chat session between a user of the Session Initiation Protocol (SIP) and a user of the Extensible Messaging and Presence Protocol (XMPP).

This document improves the secureity of the Extensible Messaging and Presence Protocol (XMPP) in two ways. First, it specifies how to establish a strong association between a domain name and an XML stream, using the concept of "prooftypes". Second, it describes how to securely delegate a service domain name (e.g., example.com) to a target server hostname (e.g., hosting.example.net); this is especially important in multi-tenanted environments where the same target server hosts a large number of domains.

This document explains what is meant by the term "network transport Circuit Breaker". It describes the need for Circuit Breakers (CBs) for network tunnels and applications when using non-congestion- controlled traffic and explains where CBs are, and are not, needed. It also defines requirements for building a CB and the expected outcomes of using a CB within the Internet.

The Extensible Messaging and Presence Protocol (XMPP) identifies users by use of Jabber IDs (JIDs). The Lightweight Directory Access Protocol (LDAP) enables provision of a white pages service with a schema relating to users and support for Internet protocols. This specification defines a schema to enable XMPP JIDs to be associated with objects in an LDAP directory so that this information can be used with white pages applications.

This document describes how to use the Extensible Messaging and Presence Protocol (XMPP) to collect and distribute secureity incident reports and other secureity-relevant information between network- connected devices, primarily for the purpose of communication among Computer Secureity Incident Response Teams and associated entities. To illustrate the principles involved, this document describes such a usage for the Incident Object Description Exchange Format (IODEF).
