Protocol support ---------------- jabberd 2.0 is a server implementation of the eXtensible Messaging and Presence Protocol (XMPP), as published by the IETF. It also implements several XMPP extensions documented by the Jabber Software Foundation (JSF), and some legacy extensions that were implemented by its predecessor, jabberd 1.4. This document lists the protocols supported by the server, and any notes relating to the implementation. This is current as of 2005-04-04 (jabberd 2.0s9). XMPP ---- XMPP Core (RFC 3920) Implemented, except for: - SASL for s2s streams - Language support via xml:lang XMPP IM (RFC 3921) Implemented. JSF Extensions -------------- Jabber Browsing (JEP-0011) Implemented by the session manager (mod_disco) as a wrapper around the service list used for Service Discovery. The configuration required to enable browsing is undocumented as browse is considered to be deprecated. Last Activity (JEP-0012) Implemented by the session manager (mod_iq_last). Message Events (JEP-0022) Offline event implemented by the session manager (mod_offline). Message Expiration (JEP-0023) Implemented by the session manager (mod_offline). Service Discovery (JEP-0030) Implemented by the session manager (mod_disco). Administrative users will see extra nodes when doing a #items query - these nodes provide information about active users and sessions. New components becoming available are probed automatically, and if they are disco-aware, their information is added to the service list. Sub-entity item publishing is implemented seperately by mod_disco_publish. Private XML Storage (JEP-0049) Implemented by the session manager (mod_iq_private). vcard-temp (JEP-0054) Implemented by the session manager (mod_iq_vcard). In-band Registration (JEP-0077) Implemented by c2s. Non-SASL Authentication (JEP-0078) Implemented by c2s. Legacy Errors (JEP-0086) Implemented. Entity Time (JEP-0090) Implemented by the session manager (mod_iq_time). Delayed Delivery (JEP-0091) Implemented by the session manager. Software Version (JEP-0092) Implemented by the session manager (mod_iq_version). Agent Information (JEP-0094) Implemented by the session manager (mod_disco) as a wrapper around the service list used for Service Discovery. External Component Protocol (JEP-0114) Implemented by the router as a wrapper around the more featureful jabberd 2.0 component protocol. Legacy extensions (jabberd 1.4) ------------------------------- Invisible presence Implemented by the session manager. Note that the JSF version of this as documented in JEP-0018 is substantially different to the traditional implementation.
