Publish-Subscribe (XEP-0060) XEP-0060: Publish-Subscribe <https://xmpp.org/extensions/xep-0060.html>. and Personal Eventing Protocol (XEP-0163) XEP-0163: Personal Eventing Protocol <https://xmpp.org/extensions/xep-0163.html>. can be used to publish a wide variety of "extended presence" information about users. This document specifies an extended presence payload format that communicates information about the games a user plays. This information may be of interest to a user's contacts and can also be used in social networking applications.

Information about games is provided by the user (or automated integration with gaming systems) and is propagated on the network by the user's client. The information container for gaming data is a <game/> element that is qualified by the 'urn:xmpp:gaming:0' namespace. The game information itself is provided as the XML character data of the following children of the <game/> element:

Element Description Example Datatype Inclusion
character_name The name of the user's character in the game Stentor xs:string OPTIONAL
character_profile A URI for a profile of the user's character http://wow.example.com/profile.html?12345 xs:anyURI OPTIONAL
name The name of the game Worlds of Warfare xs:string REQUIRED
level The user's level in the game 66 xs:string OPTIONAL
server_address The hostname or IP address of the server where the user is playing wow6.example.com xs:string OPTIONAL
server_name The name of the server where the user is playing WOW Example xs:string OPTIONAL
uri A URI for the game or relevant gaming service http://wow.example.com/ xs:anyURI OPTIONAL

NOTE: The datatypes specified above are defined in XML Schema Part 2 XML Schema Part 2: Datatypes <http://www.w3.org/TR/xmlschema11-2/>..

When a user starts playing a game, its client may publish that fact to PEP node whose NodeID is "urn:xmpp:gaming:0" (see Protocol Namespaces regarding issuance of one or more permanent namespaces) or to a generic pubsub node. Because gaming information is not pure presence information and can change independently of the user's availability, it SHOULD NOT be provided as an extension to the <presence/> stanza type.

The gaming information is then delivered to all subscribers:

chess http://www.chesspark.com/ ]]>

When the user stops playing the game, the user's client SHOULD send an empty <game/> element with the same ItemID:

]]> ]]>

The games that a user plays may be sensitive. A client MUST provide a way for a user to configure which games or types of games will not be published (e.g., via user preferences).

This document requires no interaction with the Internet Assigned Numbers Authority (IANA) The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of unique parameter values for Internet protocols, such as port numbers and URI schemes.

This specification defines the following XML namespace:

  • urn:xmpp:gaming:0

Upon advancement of this specification from a status of Experimental to a status of Draft, the XMPP Registrar The XMPP Registrar maintains a list of reserved protocol namespaces as well as registries of parameters used in the context of XMPP extension protocols approved by the XMPP Standards Foundation. For further information, see <https://xmpp.org/registrar/>. shall add the foregoing namespace to the registry located at <https://xmpp.org/registrar/namespaces.html>, as described in Section 4 of XMPP Registrar Function (XEP-0053) XEP-0053: XMPP Registrar Function <https://xmpp.org/extensions/xep-0053.html>..

If the protocol defined in this specification undergoes a revision that is not fully backwards-compatible with an older version, the XMPP Registrar shall increment the protocol version number found at the end of the XML namespaces defined herein, as described in Section 4 of XEP-0053.
