I have been scanning and adding cover art for a bit now and have a decent list of releases finished. I am still adding but have slowed down since winter is over. All releases in this list have complete cover, booklet, back, and spine scans in high rez and made in a complete sRGB calibrated workflow ( some colors just can’t be scanned correctly though like reflective gold and silver inks. But back to the point. It is a good list that has all the information needed for relationships if available. I have finished some of them but have been focusing on getting the scans uploaded, song titles, ISRC, AcousticBrainz, and acoustic ids. So if you are good with relationship editing and are bored this list has all the info ready. Just thought I would throw it out there.
Speaking of Wikidata, if you take a look at my artist subscriptions then it’s 100% certain there are a lot of artists that could use more relationships. Not to mention all the releases and series.
