Each client is either an <em>observer</em>, an + <em>approver</em>, a <em>channel handler</em>, or some combination + of these.</p> + + <tp:rationale> + <p>Activatable services (those with a D-Bus <code>.service</code> + file) must be supported so that we can run clients + in response to channel creation.</p> + + <p>Non-activatable services (those that do not register a D-Bus + <code>.service</code> file for their well-known name, but do + request it at runtime) must be supported so that we can have + programs that process channels, but only if they are already + running - for instance, a full-screen media centre + application might do this.</p> + </tp:rationale> + + <p>The client name, <em>clientname</em>, MUST be a non-empty string of + ASCII digits, letters, dots and/or underscores, starting with a + letter, and without sets of two consecutive dots or a dot + followed by a digit. For non-activatable services, it MAY contain a + part that is generated per instance at runtime.</p> + + <tp:rationale> + <p>If each of a client Foo's instances should be able to manipulate + channels separately, the instance with unique name + <code>:1.25</code> might request a well-known name like + <code>org.freedesktop.Telepathy.Client.Foo._1._25</code>.</p> + + <p>(Note that well-known bus-name components may not start with a + digit, so o.f.T.Client.Foo.1.25 would not be acceptable.)</p> + </tp:rationale> + + <p>Each Client MUST export an object whose object path may be + determined by replacing '.' with '/' in the well-known name and + prepending '/'. This object represents its API as a Telepathy + client; the channel dispatcher will call its methods and read + its properties when appropriate.</p> + + <p>As an optimization, activatable clients SHOULD install a file + <code><a href="http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html">$XDG_DATA_DIRS</a>/telepathy/clients/<em>clientname</em>.client</code> + containing a cached version of its immutable properties, + so that for most clients, the channel dispatcher can + just read a file to discover capabilities, instead of + having to service-activate the client immediately in order to fetch + its read-only properties. However, the D-Bus API is canonical, and + the channel dispatcher MUST support clients without such a file.</p> + + <p>Non-activatable clients MAY install a <code>.client</code> file, + but there's not much point in them doing so.</p> + + <p>The .client files MUST contain UTF-8 text with the same syntax + as + <a href="http://standards.freedesktop.org/desktop-entry-spec/latest/">Desktop + Entry files</a> (although the allowed groups, keys and values differ). + Every <code>.client</code> file MUST contain a group whose name is + the name of this interface.</p> + + <p>The groups, keys and values in the <code>.client</code> file are + defined by individual interfaces.
