All in all, if we can write a library which can read a page with
schema.org data encoded and spit out RDF, who cares?
I'm looking the examples, and it looks easy enough to turn into triples,
albeit there will often be graphs with nothing but bnodes.
There's no way normal web developers will assign URIs to things until
they see the benefit... Could we suggest a trivial extension to
schema.org to let people add URIs for itemtypes.
<div itemscope itemtype="http://schema.org/Organization";
about="http://totl.net/#org";>
If I had more hack-slack I'd knock up a library which takes a schema.org
encoded page and spits out triples.
Are people going to create some semantic abominations using schema.org?
of course, but they were already able to do that in RDFa. This is going
to be used by the same kind of people who were implementing RSS a decade
ago. Just accept that the world is going to end up with a big pile of
shonky data!
schema.org is so very much more human-readable than RDFa. It wins hands
down on that.
We're the linked data community. RDF is a tool to an end, no more.
Rather than sit around and feel glum about this coming wave of data
being a bit wrong, we should be looking at how to help it become Linked
(and Open).
I think we made a big mistake in using http URIs. It's too confusing. If
we'd used <thing://totl.net/> with the convention that you can find
facts about it by converting "thing:" to "http:" then the world would be
much less confused about URIs. I know this is probably an old topic of
conversation, but it's a massive impediment to the public understanding
of URIs for things not available via the HTTP protocol.
I'm amazed that people are so surprised about schema.org. Don't you
realise that RDFa, RDF/XML and using http:// URIs for real world things
is really really confusing and make the amazingly useful idea of Linked
Open Data much harder to get to groups with?
These days when I teach people about RDF data I start with N-Triples as
it's the easiest format to grok.
Sorry for getting a bit ranty, but this community has no focus on
lowering the barriers which make it hard for the mainstream web
community to start producing linked data. I find that very very frustrating.

All,
Thanks a lot for the comments we received so far, both here and (even more)
off-list. Now, to make our life a bit easier, may I ask you to provide
suggestions concerning the mapping (or feature requests alike) directly to
the Github [1]? Of course, if you're more into it, feel free to clone the
repo and issue a pull request.
As you can imagine, this is a community endeavour - we just happened to kick
it off ;)
Actually, I'm also going to point out that the W3C asked for EU
funding about a year ago for something *very* similar - and at the
time had the interest even of Google - for hosting a RDF version of
something quite similar to schema.org. But thanks to the wonderful
judgement of the reviewers of EU proposals and the Semantic Web
academic community, we weren't given funding :)
Obviously Google and friends see a good opportunity here to actually
make a place to find structured data vocabularies on the Web. While I
wish they had better support for RDFa, I can see that the whole
RDFa/microdata/microformats lack of convergence is causing a confusing
mess for ordinary webmasters.
cheers,
