7and some legacy extensions that were implemented by its predecessor,
8jabberd 1.4.

108Implementation Notes
109--------------------
110
111
112XMPP RFCs
113---------
114
115XMPP Core (RFC 3920 and RFC 3920bis)
116
117 Implemented, except for:
118  - SASL (External) for s2s streams
119  - Language support via xml:lang
120
121XMPP IM (RFC 3921 and RFC 3921bis)
122
123 Implemented.
124
125
126XMPP Extension Protocols
127------------------------
128
129Jabber Browsing (XEP-0011)
130
131 Implemented by the session manager (mod_disco) as a wrapper around the
132 service list used for Service Discovery. The configuration required to
133 enable browsing is undocumented as browse is considered to be
134 deprecated.
135
136Last Activity (XEP-0012)
137
138 Implemented by the session manager (mod_iq_last).
139
140Message Events (XEP-0022)
141
142 Offline event implemented by the session manager (mod_offline).
143
144Message Expiration (XEP-0023)
145
146 Implemented by the session manager (mod_offline).
147
148Service Discovery (XEP-0030)
149
150 Implemented by the session manager (mod_disco). Administrative users
151 will see extra nodes when doing a #items query - these nodes provide
152 information about active users and sessions. New components becoming
153 available are probed automatically, and if they are disco-aware, their
154 information is added to the service list. Sub-entity item publishing is
155 implemented seperately by mod_disco_publish.
156
157Private XML Storage (XEP-0049)
158
159 Implemented by the session manager (mod_iq_private).
160
161vcard-temp (XEP-0054)
162
163 Implemented by the session manager (mod_iq_vcard).
164
165In-band Registration (XEP-0077)
166
167 Implemented by c2s.
168
169Non-SASL Authentication (XEP-0078)
170
171 Implemented by c2s.
172
173Entity Time (XEP-0090)
174
175 Implemented by the session manager (mod_iq_time).
176
177Delayed Delivery (XEP-0091)
178
179 Implemented by the session manager.
180
181Software Version (XEP-0092)
182
183 Implemented by the session manager (mod_iq_version).
184
185Agent Information (XEP-0094)
186
187 Implemented by the session manager (mod_disco) as a wrapper around the
188 service list used for Service Discovery.
189
190External Component Protocol (XEP-0114)
191
192 Implemented by the router as a wrapper around the more featureful
193 jabberd 2.x component protocol.
194
195
196Legacy extensions (jabberd 1.4)
197-------------------------------
198
199Invisible presence (XEP-0018)
200
201 This extension was implemented by the session manager.
202 It was intentionally removed. This is very legacy, causes problems, we
203 have better ways of doing so called invisibility, etc.
