In my mind, a [release group]«is included in»[release group] relationship says this:
This album/EP was also released as part of this other, larger set.
Or in reverse,
This set includes re-releases of the following albums/EPs.
Some editors (at the time) argued that [release group]«is included in»[release] would be better, because:
- it’d be more versatile, because it would cover e.g. “this EP is also available as bonus tracks on this other release”
- any duplication of data would be minimal (since 2-in-1s and box-set release groups commonly have only one version)
- several similar relationships would be bad, because editors are confused enough already
So I’d like to hear from others on that. Does it seem like a problem to have several similar relationships? (release-release, RG-RG etc)
If the whole idea sounds dumb, I’ll happily drop the issue.
