Conflicts-with constraint

This property now has a conflicts-with constraint (Q21502838) with Encyclopaedia Metallum artist ID (P1989) which is slightly problematic. On Encyclopaedia Metallum individual musicians have their own artist pages (identified here with P1989), but if said musician has released music as a solo artist they will also have a band page (identified here with this property, P1952). Take James LaBrie and James LaBrie for example. Another problem is that oftentimes these solo artists have a band behind them, but we can’t list the members of these bands, because we can’t say that Marco Sfogli (Q3846495) is a member of James LaBrie (Q296039) because both are instances of human (Q5). Should we have a separate item for the band? Some cases like that already exist, like Axel Rudi Pell (Q433073) and Axel Rudi Pell (Q3631326). For now I have usually put the band identifier on the musician's item, which leads to a constraint violation. –Kooma (talk) 09:59, 24 July 2020 (UTC)
