which isn't really open at all in a useful way for Open Knowledge IMO.
It might only be "look but don't touch".  From what I remember, MARC21
doesn't contain a tag that specifies the licensing terms of a record,
does it?

If I've forgotten/overlooked it, can we build something on top of
index data's registry to search/show which terms have been found in a
database?

Thanks,
