Hi Tom,

Only on the alignment section:

This looks like wordsmithing. I don't feel like there is much difference in the message, it just looks clearer. Thanks!

Yes, that's good.

Fair enough.
Note that the confusion between "alignment" and "ontology mapping" is quite understandable: as soon as you include in it similarity between individuals (owl:sameAs or softer), then "ontology mapping" may cover the entire realm of semantic alignment, in the RDF(S)/OWL world.
Note that as an ontology matching researcher, I am using the terminology from that area:
- matching = the process of establishing connections (manually or using an automatized technique)
- mapping = an individual correspondence (e.g., between class A and class B)
- alignment = a set of mappings between two datasets/ontologies

So I'd propose to replace
"which provides methods for mapping equivalences across vocabularies ([http://www.w3.org/TR/2004/REC-owl-guide-20040210/#OntologyMapping ontology mapping])"
"which provides elements to represent alignments across vocabularies ([http://www.w3.org/TR/2004/REC-owl-guide-20040210/#OntologyMapping ontology mappings])"

But that's a mere suggestion. Having been confused by all that years ago (and still being quite a bit) I understand that you may be unconvinced. Even though one big plus of my wording is that it's more compatible with the section in the OWL specs, which includes "different from" links -- thus quite far from "equivalences" (an alignment can indeed also include mappings that denote dissimilarity...).
