Modified uniqueness constraint
Lists items having identical values, except if one of the items is a protein domain (Q898273) and the other a protein family associated with domain (Q81505329), see discusion below. Please don't switch on the normal uniqueness constraint, use this instead. (Help)

more specific uniqueness constraint

As we (will) have items for protein families that are associated with protein domains, and InterPro mixes both concepts into one ID, there is the necessity for finer-grained uniqueness constraints. In this case there should be no conflict if one of the conflicting items is either a protein domain (Q898273) or a protein family associated with domain (Q81505329). Can this be implemented with property configuration alone? --SCIdude (talk) 08:11, 10 January 2020 (UTC)
