My assumption was that we wanted the Direct Mapping to capture all of them and would be considered a failure if it dropped some of them (would there be a deterministic way to identify which one to drop?). But from your question it seems that it is OK for a FK to be dropped and it is just a question of how common the scenario is. In that case I would say it is not very common. Regarding ISSUE-65, it seems useful to me that the presence of a FK is purely additive in terms of the triples produced. So I agree with Souri's points and recommendation. -David
