What was the confusion about ':e2 wasQuoteFrom :e1'?

:e2 is a *quote*, even if we don't have a prov:Quote subclass. This
should make it much clearer than (slightly more grammatically correct,
but directionally confusing) wasQuotedFrom, because you know that the
domain has to be the actual quote, not just something that contains
the quote. The direction is also clear, the quote is :e2 on the left,
the source and possibly bigger entity is :e1 on the right.

OK, what about 'quoteFrom' then. No verb - but if you insist we can't
use past tense on this one, what do we do?


The argument 'what is it now' could be applied to the other
properties, is that thing no longer derived from B? Is it no longer
generated by X?  Does it no longer have that original source?  We
don't know what it has 'now' - that is undefined - provenance is about
the past, and in the past it was a quote from X.
