- Metadata extensibility
- Changing profile info generates m.presence events ("presencelike")
- keys on m.presence are optional, except presence which is required
- m.room.member is populated with the current displayname at that point in time.
- That is added by the HS, not you.
- Display name changes also generates m.room.member with displayname key f.e. room

A Profile consists of a display name, an avatar picture, and a set of other
metadata fields that the user may wish to publish (email address, phone
numbers, website URLs, etc...). This specification puts no requirements on the
display name other than it being a valid unicode string.
display name other than it being a valid unicode string. Avatar images are not
stored directly; instead the home server stores an ``http``-scheme URL where
clients may fetch it from.
Client API
----------
The client API for profile management consists of the following REST calls.
Fetching a user account displayname::
GET $PREFIX/profile/:user_id/displayname
Returned content: JSON object containing the following keys:
displayname: string of freeform text
This call may be used to fetch the user's own displayname or to query the name
of other users; either locally or on remote systems hosted on other home
servers.
Setting a new displayname::
PUT $PREFIX/profile/:user_id/displayname
Content: JSON object containing the following keys:
displayname: string of freeform text
Fetching a user account avatar URL::
GET $PREFIX/profile/:user_id/avatar_url
Returned content: JSON object containing the following keys:
avatar_url: string containing an http-scheme URL
As with displayname, this call may be used to fetch either the user's own, or
other users' avatar URL.
Setting a new avatar URL::
PUT $PREFIX/profile/:user_id/avatar_url
Content: JSON object containing the following keys:
avatar_url: string containing an http-scheme URL
Fetching combined account profile information::
GET $PREFIX/profile/:user_id
Returned content: JSON object containing the following keys:
displayname: string of freeform text
avatar_url: string containing an http-scheme URL
At the current time, this API simply returns the displayname and avatar URL
information, though it is intended to return more fields about the user's
profile once they are defined. Client implementations should take care not to
expect that these are the only two keys returned as future versions of this
specification may yield more keys here.
Server API
----------
The server API for profiles is based entirely on the following Federation
Queries. There are no additional EDU or PDU types involved, other than the
implicit ``m.presence`` and ``m.room.member`` events (see section below).
Querying profile information::
Query type: profile
Arguments:
user_id: the ID of the user whose profile to return
field: (optional) string giving a field name
Returns: JSON object containing the following keys:
displayname: string of freeform text
avatar_url: string containing an http-scheme URL
If the query contains the optional ``field`` key, it should give the name of a
result field. If such is present, then the result should contain only a field
of that name, with no others present. If not, the result should contain as much
of the user's profile as the home server has available and can make public.
Events on Change of Profile Information
---------------------------------------
Because the profile displayname and avatar information are likely to be used in
many places of a client's display, changes to these fields cause an automatic
propagation event to occur, informing likely-interested parties of the new
values. This change is conveyed using two separate mechanisms:
- a ``m.room.member`` event is sent to every room the user is a member of,
to update the ``displayname`` and ``avatar_url``.
- a presence status update is sent, again containing the new values of the
``displayname`` and ``avatar_url`` keys, in addition to the required
``presence`` key containing the current presence state of the user.
Both of these should be done automatically by the home server when a user
successfully changes their displayname or avatar URL fields.
Additionally, when home servers emit room membership events for their own
users, they should include the displayname and avatar URL fields in these
events so that clients already have these details to hand, and do not have to
perform extra roundtrips to query it.
