A Vorbis comment is a metadata container used in the Vorbis, FLAC, Theora, Speex and Opus file formats. It allows information such as the title, artist, album, track number or other information about the file to be added to the file itself. However, as the official Ogg Vorbis documentation notes, “[the comment header] is meant for short, text comments, not arbitrary metadata; arbitrary metadata belongs in a separate logical bitstream (usually an XML stream type) that provides greater structure and machine parseability.”[1] FormatA Vorbis tag is a list of fields in the format The data is encoded in UTF-8, and so any conforming Unicode string may be used as a value. Any tag name is allowed, and there is no format that the data values must be in. This is in contrast to the ID3 format used for MP3s, which is highly structured. Field names are also permitted to be used more than once. It is encouraged to use this feature to support multiple values, for example two The specification gives several example tag names such as There are no provisions for storing binary data in Vorbis comments. This is by design; they are intended to be used as part of a container format such as Ogg, and any additional binary data should be encoded into the container as a stream. The exception to this, by popular request, is a proposal to incorporate cover art into a Vorbis comment.[2] See also
