My argument for why they should not be replaced - see examples in

https://dvcs.w3.org/hg/prov/file/47b52dc6a91e/ontology/components/wasQuotedFrom-hadQuoter


https://dvcs.w3.org/hg/prov/file/47b52dc6a91e/ontology/components/wasQuotedFrom-hadQuoter/had-quoter.ttl
shows how it is now.

https://dvcs.w3.org/hg/prov/file/47b52dc6a91e/ontology/components/wasQuotedFrom-hadQuoter/had-quoter-was-attributed-to.ttl
is trying to do as Tim is suggesting - using wasAttributedTo for both
hadQuoter and hadQuoted - and why I think it does not work.

https://dvcs.w3.org/hg/prov/file/47b52dc6a91e/ontology/components/wasQuotedFrom-hadQuoter/had-quoter-roles.ttl
shows an attempt to solve this using roles - but this does not work
when there are multiple quotations.



In short, my argument is that wasQuotedFrom is more than a short hand
for some wasAttributedTo links. As we know, wasAttributedTo just means
that the agent wasAssociatedWith the activity that generated the
entity. It does not say anything else about how or to what degree that
agent was associated, it could be performing the activity, monitoring
it. In my example, based on the PROV-DM example of the Dagstuhl
blogpost paragraph, then there could be two agents who created the
blog post, but only one of which was quoted. Similarly there could be
two agents making the paragraph, but only one of them who was quoting.
