Antti Jokipii [MB: Jokipii and operator of Jokipii_bot | IRC: Jokipii | Wiki: Jokipii | Last.fm AnttiJokipii]

I am currently trying to improve linking between MusicBrainz and Discogs. I have both databases installed on PostgreSQL. Bot code can be found at musicbrainz-bot and code that produces Discogs database from monthly XML dumps found at discogs-xml2db.

Userscripts

Here is userscript that makes voting for Discogs links easier.

Bot queue

Set descriptions and number of links

In Progress

Release links identified by match on normalized catalog number, release name, linked label, format, same number of tracks, same release country, and same release year.
* 9860

Not Started

Artist Discogs links
* Exact name match. One or more already linked various artist release(s) where artist have track(s). All track(s) found that way point on same artist at Discogs.
* Example 
* 16349
Advanced relationships between releases and artists where both are already linked to discogs
* Producer Hand made example 74164
* Mastered 27970
* and certainly lots also in other relationship classes
Artist name with exact (case insensitive) match, is member of groups with Discogs links, all groups found that way have same Discogs artist as member.
* 8692
Artist (type:group) name with exact (case insensitive) match, have members with Discogs links, all members found that way have been also market as members in Discogs entry.
* 2083
Artist that have Discogs link, and not have type(person/group) set, and have multiple members in Discogs (indicating type:group)
* 1309
Artist that have Discogs link, and not have type(person/group) set, and have Discogs realname without characters "&,/+" and word "and" (indicating type:person)
* 1699

Done

Artist Discogs links
* Exact name match. Have release(s) with Discogs links. All releases found that way point on same artist at Discogs.
Artist types based on disambiguation comment
Artist country based on disambiguation comment
Artist country based on Discogs profile text
Release links identified by exact match on catalog number, release name, linked label, format, same number of tracks and same release country.

Bot programming tasks

  • Merge bot code to musicbrainz-bot Checkmark.pngDone
  • Start using discogs-xml2db to produce Discogs database Checkmark.pngDone
  • Better documentation
  • Map Discogs credits <-> MB Advanced relationships
