Re: PROV-ISSUE-356 (replace-hadquoter): Replace hadQuoter by reusing wasAttributedTo [mapping prov-dm <-> prov-o]


Thanks for the examples. I think it gives a good rational to introduce
hadQuoter. The question is in general *who* do we need to identify? I
think the possibilities are:

- The person being quoted
- The person doing the quoting

I think a clearer predicate would be quotationAttributedTo but that
doesn't follow our predicate naming approach. Also, there's a question
as to whether introducing these extra relations helps or hurts. Do we
need to model more than attribution relation for a quotation?

Thanks for bringing this up,
