I am not sure about the terminology of name, kind, label, type, etc. As far as I can see, we have * the media type: video, audio, text, metadata (undisplayed temporal data), maybe one or two others * the container type: MP4, WebM, etc. * the coding type: VP8, H.264, Vorbis, etc. * the function, purpose, role, etc. (currently called 'kind'): main, sign-language, dubbed, alternate, supplementary, commentary, * label: some kind of user-displayable label for the track, maybe, but this gets into internationalization issues (in how many languages do I supply the label string?) MIME covers the first two, and with a codecs parameter, the first three. I absolutely need the 4th (role) in order to match up what a user wants with what's being offered. The 5th, I am not sure...
