Dear Robert,
my comments inline.

the use case I presented is already in production (with Annotation Ontology
and PAV) and the idea is that Domeo tracks both the primary and the
secondary actors as they are both important.
In my case (biomedicine and science) the secondary actor is also very
important as there could be some substantial 'curation' involved and you
are really interested in knowing who performed it. I've used the Darwin
example as that is the one we put in the specs.

The way Domeo works is that we have 'annotation sets' that are created by
an agent but can then enriched and modified by other agents to whom the
first agent gave editing permissions.
We are basically allowing for crowd sourcing of the annotation creation and
curation (normally to scientists or scholars).

Surely you can have cases in which the whole annotation set is contributed
by one single agent, but that is not always the case. For instance, I can
crowd source to an entire class the task of encoding all the annotations of
a manuscripts and the editor could be the instructor. The students might be
even evaluated for their individual contributions.
Again that is just an example, in general the idea with Domeo is to allow
flexibility in the management of annotations and their collections.

I tend to track both agent and the application that has been used to
perform the task. When something is not accurate or even wrong I would want
to know what happened. Even the simple association task could require some
expertise.

I am not sure I fully comprehend the two questions. I'll give it a shot and
you can tell me if I am off topic.

I  track the agent that contributed the annotations. Some of this agents
can be students, some researchers, some students and so on.
By using proper provenance it is possible to distinguish all the possible
cases. In some contexts that is a very important distinction.
If we annotate classroom material we probably want to know if the comments
has been made by a students, by an instructor or by a very important expert
in the field.
Also we can have annotation of annotations. So a student/instructor can
comment on an existing annotation and so on.

In any case, getting back to my original email, I am debating how the
listed PAV properties and oa:annotatedBy relate to each other. I cannot
drop the PAV properties as they guarantee me the expressiveness I need but
I want to make sure the whole representation is coherent.

Best,
Paolo
