ttMedia(4) ToolTalk Policy ttMedia(4) 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.
