Tim, Paul, Stian, all,

It is clear that, to resolve the issue discussed below, a "quote in blog entry" entity needs to be introduced into the primer. I've constructed a response below, based on your feedback. Please also the revised primer, start of Section 3.9.


Does this seem an adequate response to Chuck?


After discussion, we agree with you that the PROV primer was still unclear, or possibly just wrong, in the way it was implying wasQuotedFrom could be used. As you say, one would not say that "X was quoted from Y" if X was not a quotation. We still believe the relation itself, as defined in the PROV specifications, is correct and unambiguous.

We have revised the primer again following your suggestion of introducing an entity that is more clearly a quotation, ex:quoteInBlogEntry, and made explicit the text actually quoted ("Smaller cities have more crime than larger ones.")

With regards to wasQuotedFrom itself, we note that "X wasQuotedFrom Y" implies that X is a quotation, and that this follows the same idea of quotation as in HTML ("The blockquote element represents a section that is quoted from another source", HTML5). PROV does not provide a relation "X was quoted from in Y".

Please see the revised primer at the link below. The relevant text and example are at the start of Section 3.9, as before.


Do you believe this now addresses your concern?

Oh just saw that html5 defines blockquote as:

"The blockquote element represents a section that is quoted from another source"

I think prov:wasQuotedFrom fits that definition perfectly.


P.S. We should write a blog post about how to use prov with html5

PROV can cover a lot of things, but I just hope we have not just made
a kind of "SGML of provenance" in that it allows anything and
recommends nothing, as then you are still just as confused after
reading the specs, and as a result everybody would end up using PROV

Yes, there's a risk that if we under specify that many will use it differently. But the WG is simply providing the core.
As long as people are conforming to Activity and Entity, we should be okay…
