Media Server Markup Language (MSML)
Abstract
The Media Server Markup Language (MSML) is used to control and invoke
many different types of services on IP media servers. The MSML
control interface was initially driven by RadiSys with subsequent
significant contributions from Intel, Dialogic, and others in the
industry. Clients can use it to define how multimedia sessions
interact on a media server and to apply services to individuals or
groups of users. MSML can be used, for example, to control media
server conferencing features such as video layout and audio mixing,
create sidebar conferences or personal mixes, and set the properties
of media streams. As well, clients can use MSML to define media
processing dialogs, which may be used as parts of application
interactions with users or conferences. Transformation of media
streams to and from users or conferences as well as interactive voice
response (IVR) dialogs are examples of such interactions, which are
specified using MSML. MSML clients may also invoke dialogs with
individual users or with groups of conference participants using
VoiceXML.
