NAME
       ttMedia - introduction to Media Exchange messaging conventions

DESCRIPTION
       The  Media  conventions  allow  a  tool to be a container for arbitrary
       media, or to be a media player/editor that can be driven  from  such  a
       container.  These conventions allow a container application to compose,
       display, edit, print, or transform a document  of  an  arbitrary  media
       type,  without  understanding  anything  about the format of that media
       type.  ToolTalk routes container requests to the user's preferred  tool
       for  the  given  media  type  and operation.  This includes routing the
       request to an already-running instance of the tool if that instance  is
       best-positioned to handle the request.
