I'm configuring the Rules in the seo_rules.sem file for the Refactor engine.
I'm using the attached document as a reference.

It's not clear to me the difference between the *has* and *values* rules.
E.g. in the default seo_rules.sem file I can find both the following rules:

   - peopleHomepageRule[is(dbpedia:Person, ?x) . has(foaf:homepage, ?x, ?y)
   -> has(google:url, ?x, ?y)] .
   - organizationHomepageRule[is(dbpedia:Organisation, ?x) .
   values(foaf:homepage, ?x, ?y) -> values(google:url, ?x, ?y)] .

Why in one case *has* has been used and in the other *values*? Is there any
practical example about the difference between the two?

Thanks,
David
