Feature Profiles
================

.. _sect:feature-profiles:

Matrix supports many different kinds of clients: from embedded IoT devices to
desktop clients. Not all clients can provide the same feature sets as other
clients e.g. due to lack of physical hardware such as not having a screen.
Clients can fall into one of several profiles and each profile contains a set
of features that the client MUST support. This section details a set of
"feature profiles". Clients are expected to implement a profile in its entirety
in order for it to be classified as that profile.

Clients
-------

Stand-alone web (``Web``)
~~~~~~~~~~~~~~~~~~~~~~~~~

This is a web page which heavily uses Matrix for communication. Single-page web
apps would be classified as a stand-alone web client, as would multi-page web
apps which use Matrix on nearly every page.

Mobile (``Mobile``)
~~~~~~~~~~~~~~~~~~~

This is a Matrix client specifically designed for consumption on mobile devices.
This is typically a mobile app but need not be so provided the feature set can
be reached (e.g. if a mobile site could display push notifications it could be
classified as a mobile client).

Desktop (``Desktop``)
~~~~~~~~~~~~~~~~~~~~~

This is a native GUI application which can run in its own environment outside a
browser.

Command Line Interface (``CLI``)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This is a client which is used via a text-based terminal.

Embedded (``Embedded``)
~~~~~~~~~~~~~~~~~~~~~~~

This is a client which is embedded into another application or an embedded
device.

Application
+++++++++++

This is a Matrix client which is embedded in another website, e.g. using
iframes. These embedded clients are typically for a single purpose
related to the website in question, and are not intended to be fully-fledged
communication apps.

Device
++++++

This is a client which is typically running on an embedded device such as a
kettle, fridge or car. These clients tend to perform a few operations and run
in a resource constrained environment. Like embedded applications, they are
not intended to be fully-fledged communication systems.
