This page describes a proposed update to the minimal list of 15 standard field names in the Vorbis I specification. Please keep discussion confined to the Discussion page (or, better, the <vorbis-dev> mailing list).
After the proposal has been discussed, and accepted or rejected, this page should be deleted.
Analysis
To determine what field names are being used in the wild, the following resources were analysed:
- Reactor Core proposal
- Carnival of Technology proposal
- Proposals on the XiphWiki VorbisComment page
- OggImporter to Spotlight
- EasyTAG tagging program (routine "ogg_tag.c" in the source code)
- Mp3tag tagging program (post in the Mp3tag Forum)
The analysis is presented as an Excel spreadsheet (note that it contains two sheets, the first of which is the more interesting).
Proposal
The following modest list of additions to the minimal list in the specification is proposed:
COMPOSERTRACKTOTAL– complements the existingTRACKNUMBERDISCNUMBER– used if part of a multi-disc albumDISCTOTAL– total number of discs in a multi-disc albumENCODED-BY– see VorbisComment pageENCODER– see VorbisComment pageMETADATA_BLOCK_PICTURE– see VorbisComment pageSOURCEMEDIA– recommended because two different field names have been proposedPRODUCTNUMBER– recommended because two different field names have been proposed
The field names SOURCEMEDIA and PRODUCTNUMBER could be dropped if Xiph does not wish to prescribe field names. (The alternatives which have also been proposed to store the same information are SOURCE MEDIUM and EAN/UPN, respectively.)
The field name REMIXER has not been included as its use is covered by the existing VERSION.
The triple RIGHTS, RIGHTS-DATE, RIGHTS-URI, proposed on the VorbisComment page, has not been included because this is structured metadata. VorbisComments are inherently unstructured and this should be respected.
