related annotation use case?

[Bruce D'Arcus]

So I'm wondering if the use cases that have evolved in this thread I
started in the Sakai community ...

<http://collab.sakaiproject.org/pipermail/pedagogy/2010-September/000573.html>

... and in particular:

<http://collab.sakaiproject.org/pipermail/pedagogy/2010-September/000578.html>
<http://collab.sakaiproject.org/pipermail/pedagogy/2010-September/000582.html>

... might have some relevance for this project? I'm particularly
wondering if there's any work on open source annotation code libraries
that might be shared across projects.

Bumping this, since I never got a reply.

Also, the discussions have been evolving to also include a case of
certain relevance here, where has something like an annotation graph;
e.g. where an annotation threaded discussion points to the target.
See:

<http://confluence.sakaiproject.org/display/3AK/Source+Materials>

I presume this is easy enough to support in the current RDF model, but
just want to double check.

Hi Bruce,

Sorry for not replying!

Yes, it definitely seems relevant.  And yes, we explicitly model Replies in the data model.

In Alpha2: 
   http://annotation.lanl.gov/alpha2/#DM_Reply

Or in the not-quite-finished Alpha3:
   http://annotation.lanl.gov/alpha3/#DM_Types

Many thanks!

Ah, cool!

I added a link here to this page comments:

<http://confluence.sakaiproject.org/display/3AK/Source+Materials>

My impulse is to want to treat a reply as a predicate, but I guess
treating it as a class is more consistent with the rest of the OAC
model.

Oh, and just to be concrete with an example use case:

I am an instructor reading a discussion forum post by a student, in
order to assess it for a grade, and provide feedback to the student. I
want to highlight a segment of a sentence in that post and to attach
some kind of comment to it. That comment may be some kind of
pre-defined item (say, something that indicates it's vague, or
awkward), and/or some specific free text content from me.

So followup question on this ...

I have no definitive position on this, but I'm just wondering the
implications of the class-based logic if you have a system (like an
LMS, or even some blog software) where you have discussion threads
that in some cases standalone (say in the context of a forum), and in
other cases might get attached to annotation targets.

If you were designing this system from scratch, would you just say all
discussions involve oac:Annotation classes and subclasses, but just
just some of them have specific sub-document targets, and some have
more implicit global targets?
