The audio world (which is a superset of the DAW world) has nothing remotely like standards for session files. The closest thing you could maybe name is AAF, which is really from the broadcast world, and is an abomination (it carries every hallmark of design-by-committee that you could ever list). The good news is that people rarely move sessions from DAW to DAW, and on the occasions when they need a workflow that revolves around "stems" (1 audio file per track) generally gets the job done.
