Using Paolo's images, @Lutz, if you did not have oax:hasSemanticTag, how
would you related those two annotations? I think it is important to
understand the kind of relations you are dealing with. Do they come from a
controlled vocabulary? Do you want users to create a new annotation that
relates the other two? In the last case, how do you expect users to
"suggest"/"choose" relations?

In Paolo's example, would a relationship such as "exampleOf" or "subsetOf"
make sense? What is your use case for relating annotations?

@Paolo, what about this other scenario: I annotate a fragment of a document
with a note "aim" (note 1) and later another fragment with a note "result"
(note2). A relationship between them could be note2 supports/addresses note
1. In that particular case, I guess oax:basedOn would not work. So, could I
use a third annotation to establish that statement? It is more or less what
people do when reading and analyzing documents, you make some notes and
some times you relate them.

I would also recommend CMaps.
