Hi,

That was what I thought should be the case in the original version of ProvRDF.  

I think the goal is to re-use as much of OWL's annotation infrastructure as possible.  I'm not sure if that will work.

One counter-question:  Do the attributes on hasAnnotation records refer to the annotated thing, the note linked to the annotated thing, or to "the hasAnnotation record itself"?

that is, are the following equivalent:

note(n2,[ex:style="dotted"])
hasAnnotation(u1,n2)

and
hasAnnotation(u1,n2,[ex:style="dotted")

There are no examples in the DM document showing hasAnnotation with a non-empty list of attributes.
