But I guess for OpenPHACTS this doesn’t apply, since I understand from what you say below that you never mint a URI of your own where you know there is an external one.
Although it does beg the question, perhaps, of what you do when you alter find equivalences.

We don’t focus on the link predicate so much as the metadata associated with the linkset which tells us why the concepts in the two datasets are equated. For example, between two chemical databases we may have multiple linksets which use different properties for equivalence; one linkset may be because they have the same chemical structure and in another linkset we have a different set of links with the justification that they have the same chemical name. These are then used to satisfy different use cases. You can find a fuller description in
