Hi Robert,
don't get me wrong: For most of the RDF cases Open Annotation is fine. I
was talking here about non-RDF use cases, e.g. HTML.
You gave one example yourself:
<a
href="http://www.openannotation.org/spec/core/core.html#FragmentURIs";>AnchorText</a>
or <a href="http://en.wiktionary.org/wiki/house#English-abode";>the
meaning of house in the sense of abode</a>
You can not put RDF into the "href" attribute and you would need extra
infrastructure (a server + service for minting and resolving URIs) to
send around a simple link.

Dear all,
Thank you for the comments on Open Annotation!
We agree, of course, that fragments are extremely important. In Open
Annotation we have a hybrid approach consisting of three parts:
* If the resource can be described solely using fragments, then we
promote that.
http://www.openannotation.org/spec/core/core.html#FragmentURIs
* However there are situations when we need more information than can
be provided in a fragment, such as also adding the time of the
representation or providing style information for the segment, then we
introduce a FragmentSelector resource that provides the fragment
syntax along with this additional information.
http://www.openannotation.org/spec/core/specific.html#FragmentSelector
* And then there are the situations where the fragment syntax isn't
sufficient or doesn't exist. For example circles or arbitrary paths
in spatial dimensions, arbitrary text in any textual resource, or
selections in resources with media types that do not have fragment
definitions at all. In these cases we have to look elsewhere, and use
additional Selector resources.
http://www.openannotation.org/spec/core/specific.html#Selectors
We would be very happy for additional engagement and discussion in
this area as to best practices and recommendations.

Open annotation is great. Really powerful and well designed
ontology and model. It doesn't replace fragment ids, however. Both
are necessary:
frag ids to link with in simple use cases (e.g. HTML) and the
other one to annotate properly.
A bridge between them would be nice.
All the best,
Sebastian

Hi Sebastien,
I use latex as well. Utopia is a pdf reader.
But utopia does support referencing bits of the pdf. As I
understand, they are moving to extending the open annotation
ontology. I've cc'd Steve Pettifer who created Utopia and who
will known the ins-and-outs.
Currently, they store all the annotations separately.
Thanks
Paul

Hi Paul,
personally for me latex works best, because it has good
editors and support for description logic formulas. Plus it
is widely used and quite good for PDF typesetting.
It would be really swell to be able to address content within
PDF with identifiers. Did Utopia solve that problem?
I am asking along the lines of
- mediafragments [1]
- RFC 5147 text fragment identifier (see the example at the
bottom of [2])
- xpointer/xpath [3]
If yes, I would like to use it immediately. There are plans
to convert the Google Mention corpus (which includes PDF's)
to NIF [2] .
The PDF Open Parameters provided by [4] are way too simple.
All the best,
Sebastian

Hi Sarven,
Beyond the PDF for me is moving beyond the current research
communication system as highlighted by the Force 11
manifesto (http://www.force11.org/white_paper). This
includes adopting technologies that augment/extend (i.e. go
beyond) existing technologies. For example, making data
easily accessible and citable, providing links to online
content, making multiple perspectives on content available,
exposing provenance, using altmetrics. I'm very influenced
by the work on Utopia (http://utopiadocs.com) so that's why
I think using pdfs are fine - you can do a lot with them as
they stand - and for a certain form of communication
(written long form text) they work well. As technologist we
need to make sure that these new technologies work well in
the environment and connect to other things.
cheers
Paul

Paul, I have one last question for you if you don't
mind, because it seems like you are not interested in
playing this out and I don't want to bother you further:
what does "beyond the PDF" mean to you?
