One work in several tracks?

Could you clarify how one work can be split up in several tracks like in classical works? pronik 08:57, 7 April 2009 (UTC)

Let's say you have work "A" and tracks "A1", "A2", "A3", then you simply add ARs between A1->A, A2->A and A3->A. LukasLalinsky 09:13, 7 April 2009 (UTC)
What about order and work part <-> track relationship? How do we know that A2 is the second part of A? pronik 11:32, 7 April 2009 (UTC)
We don't, that's a known limitation and it's meant to be solved by the next version (something like http://users.musicbrainz.org/~luks/tmp/works.png), where you explicitly specify the attribute (part number, symphony number, anything defined by the work type).

Terminology

  • Is it a good idea to rename 'modpending' to 'editpending', to catch up with current terminology? --zout 07:55, 21 April 2009 (UTC)

Questions

  • Is it possible to have ARs for release groups that do not apply to specific discs? I have a box set with previously released albums. The box set has liner notes unique to the box. --zout 23:36, 25 April 2009 (UTC)
No, release groups actually won't know anything about discs. Some box sets will still be tricky to represent in the database. Lukáš Lalinský 06:44, 29 April 2009 (UTC)
With 'discs', I meant 'albums'. Am not yet familiar with the correct terminology. My case: I have releases Bob Dylan and Live at The Gaslight 1962 (and 8 other albums) in a box set. That box set has liner notes only available in that box set. Can I link an AR to the writer of the liner notes for the box set only? --zout 11:24, 29 April 2009 (UTC)
  • Is it possible to have more than one label/catalog number combination for a single release event? And are separate catalog numbers for discs supported? --zout 23:36, 25 April 2009 (UTC)
Yes, one release can have multiple label/catalog number pairs. And yes, these pairs will be linked to release mediums, which will effectively allow for this. Lukáš Lalinský 06:44, 29 April 2009 (UTC)
  • Why do we have a table called track and a table called recording? What purpose do they serve?
I think the NGS page explains it well. Lukáš Lalinský 19:45, 7 July 2009 (UTC)
  • Why does the recording table have an artist_credit that is not an FK and track does as well, but there its not an FK? Is this a graph error?
Error in the diagram, it's fixed now. Lukáš Lalinský 19:45, 7 July 2009 (UTC)
  • Why do both recording and track have an artist_credit and name?
Because that's what humans tend to use as identifiers. :) They normally wouldn't know "b98ee5f2-0b07-4da6-913c-acfe19d4578d", but they mostly likely do know what "Thriller by Michael Jackson" is. That's for recordings. I think it's obvious why tracks need to have artist credits and names. Lukáš Lalinský 19:45, 7 July 2009 (UTC)
