In a recent session at the Semantic Technology Conference in San Jose,
People from google indicated that they would be interested to pick up
article citation information from web pages if it was incoded in RDFa.
Since there is no RDF binding for OpenURL, and since it would be
straightforward to produce one, I wonder if anyone is interested in
helping me to do that.

This seems like it falls completely into the same domain as BIBO:
http://bibliontology.com/
When you say "RDF binding for OpenURL" you mean for the
"ContextObject" bits of OpenURL (the ctx meta metadata, rft meta
metadata, svc meta metadata, etc)? Or would this include making RDF
bindings for the SAP1/2-specific metadata formats?

Yes, it would seem that BIBO is in the same space; I need to look at it more to see what the fit is. I wonder if Bruce is still on this list.
I think you would need both the ContextObject and the metadata formats.

Yes. My publications are encoded in BIBO RDFa over at my site if
you're curious (though it probably needs a little work):

I confess to being entirely skeptical about OpenURL, but it may be
that I just don't understand it. What would a ContextObject look like
in the context of idiomatic RDF/RDFa/BIBO/DC?

Hi:
Funny you should just have asked that Bruce. I was just looking for (and
just found) an early OWL spec for ContextObject which I was noodling with
back in '03. (Tempus fugit.)
I haven't reviewed this at all, so be kind. Was just an early attempt to
model CO with OWL. Oh, I notice it uses the earlier homegrown identifiers
(ori/uri/xri) that wecontemtplated in OenURL before firmly switching to URI.
May be less than useless.
Cheers,
Tony

Funny you should just have asked that Bruce. I was just looking for (and

I haven't reviewed this at all, so be kind. Was just an early attempt to

(ori/uri/xri) that wecontemtplated in OenURL before firmly switching to URI.

OK, googling, I found this:
<http://microformats.org/wiki/OpenURL_1.0_(Z39.88)>
So:
a) the ContextObject is in fact the same as what BIBO (and DC) covers.
b) OpenURL adds a "location of resolver to parse the metadata and
present contextual services based on said metadata"
So my skepticism is that I have a hard time understanding the point of
OpenURL is in the context of RDFa.
1) BIBO and DC already provide a good foundation for describing the resources.
2) The embedded RDFa metadata gets extracted (likely often client
side) using generic parsing rules.
Why can't any "contextual services" be based on that, without need for
a resolver location?

This isn't entirely true. Z39.88 could, theoretically, be used for
contextual services for anything, not just bibliographic resources.
The reality is that the overwhelming majority of current
implementations, however, are limited to bibliographic resources (and
all of the currently registered metadata formats and community
profiles have a bibliographic flair).
Despite the best intentions of the NISO committee that designed it, I
think that, realistically, this will be all it's ever used for in any
significant quantity.
Still, I just wanted to clear that up.
