[mb-style] Clarification about release type: album or compilation

[Olivier]

Hi,

There has been some discussion lately about the proper release type to
be added to "bundled" stuff (twofers and such) (eg: album or
compilation).

It seems that http://wiki.musicbrainz.org/ReleaseType holds some
ambiguity, especially this part:

"The MusicBrainz project does not generally consider the following to
be compilations:
     a release containing two releases (and/or EPs) released together
as a single unit."

(the "single unit" being the ambiguous part)

Moreover, this seems to be at odds with the general style guide,
http://musicbrainz.org/style.html which includes the following line.

"Compilation. A compilation is a collection of previously released
tracks by one or more artists."

As a first attempt at trying to sort this out, we would like your
opinions (eg: album or compilation) on the following examples. We'd
also like to know how most people have read this so far, and if
possible, what was the initial intent of
http://wiki.musicbrainz.org/ReleaseType

(i) - two discs (vinyl or cds), identical to two previously released
albums, with no alterations of the cover art, bundled together in some
way

(ii) - two discs, identical to two previously released albums, bundled
in a new packaging, under a new release title

(iii) - one disc, containing exactly two previously released albums,
under a new name of type "Release A / Release B"

(iv) - one disc, containing exactly two previously released albums,
under a new name *not* of type "Release A / Release B"

(v) - one disc, containing one previously issued release, with
additional (previously unissued) tracks

(vi) - a set of discs, containing previously issued releases (possibly
with "additional" tracks), stacking tracks on discs with no respect
for the separation "one disc = one original release" (eg: "complete"
edition/anthology boxset).


Thank you all for your input.
