JIRA ticket http://tickets.musicbrainz.org/browse/STYLE-331
This links two release group when one, typically a compilation or multi-disc collection, includes another.
A release group "includes" another when it retains:
- The track list in essentially the same order as the original
- The original title, possibly as a medium title, a super-title in the track list, or in reproduced cover art
- Forward link phrase: includes
- Reverse link phrase: included in
- Long link phrase: includes
This relationship type doesn't allow any attributes.
A release group generally doesn't "include" singles unless it is explicitly a compilation of singles. To link a single to the album it appears on, use the Single from relationship.
