Re: New drafts - general comments and intro

I can happily live with "attached to" too!

I'm not sure why it is so odd to have semantic tag as bodies. But well, let's discuss it in another thread--there will surely be one, one day ;-)

To me the "tag" or "subject" (it could be a SKOS concept, a test-as-body, whatever) is the thing that annotates, not the thing that is annotated (NB: in fact while reading the previous versions of the spec, I had understood oa:semanticTag was playing the same functional role as oa:hasBody; I realize now I might have missed a big part of the motivation for keeping them separate then!)

And we cannot force that direction for everything. In other words, it is a matter of defining better the annotation (or the annotation process). We have a new proposal that will be shared as soon as it is polished.

Maybe the problem with "about" is that it's too much loaded with intuitive semantics that have in the end only little to do with the technical aspect of annotation. We should rather aim at finding a word that expresses a function (which carries directionality indeed).

We feel that this is somewhat counter-intuitive, as our motivation was to find a mechanism for attaching rich descriptions to aggregated resources. However, AO encourages specialisation through subclassing ao:Annotation, for instance an aot:Note relates an ann:body as a free-text note describing (a sub-selection of) the annotated document.
