In my opinion, for high data quality we should also demand a full set of hq cover art in CAA, including a scan of the medium. Otherwise, we cannot check the integrity of the data. Furthermore, keeping apart releases which differ only slightly is almost impossible without cover art.
I donât see full scans necessary if the same or even more data is available via reliable source. Booklet isnât always the most reliable source (conflicting data & recording dates often have typos). With these Hyperion releases some older releases are missing recording locations but their website might still store it.
Because of potential copyright violations and potential future collaborations with labels I wouldnât request anyone to store full sets of art (including all the pages of booklet) scanned. This isnât necessary for identifying the correct release. I typically only include front, back, spine & medium scans.
You never know if that reliable source will still be online tomorrow.
Thatâs true. Wrong info on the cover art should always be documented in the annotation.
Of course, we cannot strictly request that. But still, better have the full art work that not. If some label does not allow them being online ⌠well ⌠then their releases wonât be âhigh data qualityâ on musicbrainz.
As already mentioned elsewhere, Iâm in favor of adding an additional quality level âvery highâ. Then âhighâ could be âall available data addedâ and âvery highâ should be âall we can dream ofâ (including full cover art).
This is the only good solution I can see if we want to require full artwork for the highest level.
As a aside, isnât there a basic problem with the âdata qualityâ field, that it is always relative to the database schema at the time when it was set? If a new field were to be added (for example, ânumber of pages of bookletâ), would that suddenly make all âhigh qualityâ releases not high quality any more?
To some degree, yes Thatâs why I think âhighâ should be âall the info we canâ, but if a tiny thing is missing, but thereâs a lot of detail, it can probably still be High. Of course, thatâs probably also why @spitzwegerich wants a level where all the sources are also included and always available - because then you can add any new things from the images we already have.
