[CC'd to IETF discussion list and ietf-types discussion list] Hello, Recent changes to the page at http://www.iana.org/assignments/media-types/index.html accessed via the link from the IANA Assigned numbers page http://www.iana.org/numbers.html#M have rendered the registry of assigned media types useless. Prior to the recent change, the media types registry listed the assigned MIME top-level media types, viz. application, audio, image, message, model, multipart, text, and video. Since the change, only the application top-level type is listed (audio, image, message, model, multipart, text, and video have vanished without a trace) and superfluous repetition of the application subtypes listed in http://www.iana.org/assignments/media-types/application has appeared (these of course are not top-level media types). Could you please investigate what has gone awry and regenerate a page that provides top-level media types.
