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.
