I would like to recommend two missing relationships to be added on Musicbrainz. Hopefully I am not the only one who will think that these will be useful.
1: The first is to help document and expand upon artwork credits for releases. I think that since you already offer the possibility to put relationship credits for recording studios (through Area and Place), then a new “Place” selection could be created for “Designed at”, which could allow us to document graphic design studios where artworks are made. Right now we’re limited to only crediting the “Name” of the graphic designer, but many times personal names are not used when a firm is hired for the artwork.
2: The second is to help broaden the Person to Artist relationships links. Right now, on a Person profile, one can link a personal relationship, but this is limited to “Children”/“Parents” (Step), “Siblings” (Half, Step), “Married” and “Involved With”. Although these are great, I think they’re rather limited. This applies to me personally because one of my grandmother and several of my uncles and cousins have been involved in the music industry but I have no way to link a personal relationship with them. I think that at the very least, an “Extended Family” option should be added, to cover all of those other family members. Maybe also a (Grand) property can be added to the “Children”/“Parents” section to help with that relationship.
Looking forward to hearing people’s take on these suggestions! Happy holidays.
