This specification defines an XMPP protocol extension for data forms that can be used in workflows such as service configuration as well as for application-specific data description and reporting. The protocol includes lightweight semantics for forms processing (such as request, response, submit, and cancel), defines several common field types (boolean, list options with single or multiple choice, text with single line or multiple lines, single or multiple JabberIDs, hidden fields, etc.), provides extensibility for future data types, and can be embedded in a wide range of applications. The protocol is not intended to provide complete forms-processing functionality as is provided in the W3C XForms technology, but instead provides a basic subset of such functionality for use by XMPP entities.
This specification defines an XMPP protocol extension for communicating information about the last activity associated with an XMPP entity. It is typically used by an IM client to retrieve the most recent presence information from an offline contact by sending a last activity request to the server that hosts the account controlled by the contact.
This specification defines an XMPP protocol extension for enabling or disabling communication with other entities on a network. The protocol, which was first standardized in Section 10 of RFC 3921, can be used to block communication with unknown or undesirable entities. Blocking can be based on Jabber Identifier, subscription state, or roster group. The blocked stanzas can be messages, IQs, inbound or outbound presence stanzas, or all stanzas. The protocol also enables an entity to create, modify, or delete its privacy lists, apply different lists to different connected resources, define a default list, and decline the use of any privacy list during a particular communications session.
This specification defines an XMPP protocol extension that enables entities to include RFC822-style address headers within XMPP stanzas in order to specify multiple recipients or sub-addresses.
A protocol to enable gathering statistics from Jabber servers and components.
This specification defines an XMPP protocol extension for multi-user text chat, whereby multiple XMPP users can exchange messages in the context of a room or channel, similar to Internet Relay Chat (IRC). In addition to standard chatroom features such as room topics and invitations, the protocol defines a strong room control model, including the ability to kick and ban users, to name room moderators and administrators, to require membership or passwords in order to join the room, etc.

This specification provides canonical documentation of the jabber:iq:search namespace currently in use within the Jabber community.
This specification defines an XMPP protocol extension for generic publish-subscribe functionality. The protocol enables XMPP entities to create nodes (topics) at a pubsub service and publish information at those nodes; an event notification (with or without payload) is then broadcasted to all entities that have subscribed to the node. Pubsub therefore adheres to the classic Observer design pattern and can serve as the foundation for a wide variety of applications, including news feeds, content syndication, rich presence, geolocation, workflow systems, network management systems, and any other application that requires event notifications.
This document defines an XMPP protocol extension for establishing an out-of-band bytestream between any two XMPP users, mainly for the purpose of file transfer. The bytestream can be either direct (peer-to-peer) or mediated (though a special-purpose proxy server). The typical transport protocol used is TCP, although UDP can optionally be supported as well.
This specification defines an XHTML 1.0 Integration Set for use in exchanging instant messages that contain lightweight text markup. The protocol enables an XMPP entity to format a message using a small range of commonly-used HTML elements, attributes, and style properties that are suitable for use in instant messaging. The protocol also excludes HTML constructs that may introduce malware and other vulnerabilities (such as scripts and objects) for improved security.
This specification defines an XMPP protocol extension for in-band registration with XMPP-based instant messaging servers and other services hosted on an XMPP network (such as groupchat rooms and gateways to non-XMPP IM services). The protocol is extensible via use of data forms, thus enabling services to gather a wide range of information during the registration process. The protocol also supports in-band password changes and cancellation of an existing registration.
This document defines an XMPP protocol extension for exchanging user avatars, which are small images or icons associated with human users. The protocol specifies payload formats for both avatar metadata and the image data itself. The payload formats are typically transported using the personal eventing profile of XMPP publish-subscribe as specified in XEP-0163.
This document defines an XMPP protocol extension for communicating the status of a user in a chat session, thus indicating whether a chat partner is actively engaged in the chat, composing a message, temporarily paused, inactive, or gone. The protocol can be used in the context of a one-to-one chat session or a multi-user chat room.
This specification defines an XMPP protocol extension for retrieving information about the software application associated with an XMPP entity. The protocol enables one entity to explicitly query another entity, where the response can include the name of the software application, the version of the software application, and the operating system on which the application is running.
This document defines an XMPP protocol extension for broadcasting and dynamically discovering client, device, or generic entity capabilities. In order to minimize network impact, the transport mechanism is standard XMPP presence broadcast (thus forestalling the need for polling related to service discovery data), the capabilities information can be cached either within a session or across sessions, and the format has been kept as small as possible.
This document defines recommended best practices for service-level administration of servers and components using Ad-Hoc Commands.
This document defines mechanisms and preferences for the server-side archiving and retrieval of XMPP messages.
This document defines an XMPP protocol extension for negotiating compression of XML streams, especially in situations where standard TLS compression cannot be negotiated. The protocol provides a modular framework that can accommodate a wide range of compression algorithms; the ZLIB compression algorithm is mandatory-to-implement, but implementations may support other algorithms in addition.
This document provides historical documentation of a vCard-based protocol for exchanging user avatars.
This specification defines semantics for using the XMPP publish-subscribe protocol to broadcast state change events associated with an instant messaging and presence account. This profile of pubsub therefore enables a standard XMPP user account to function as a virtual pubsub service, easing the discovery of syndicated data and event notifications associated with such an account.

This specification defines an XMPP protocol extension for communicating the fact that an XML stanza has been delivered with a delay, for example because a message has been stored on a server while the intended recipient was offline or because a message is contained in the history of a multi-user chat room.
This document specifies an XMPP protocol extension for discovering services external to the XMPP network.
This specification defines the Server Dialback protocol, which is used between XMPP servers to provide identity verification. Server Dialback uses the Domain Name System (DNS) as the basis for verifying identity; the basic approach is that when a receiving server accepts a server-to-server connection from an initiating server, it does not process XMPP stanzas over the connection until it has verified the initiating server's identity. Additionally, the protocol is used to negotiate whether the receiving server is accepting stanzas for the target domain. Although Server Dialback does not provide strong authentication and is subject to DNS poisoning attacks, it has effectively prevented most address spoofing on the XMPP network since its development in the year 2000.
This specification defines an XMPP protocol extension for including or referring to small bits of binary data in an XML stanza.
