Manu,
I was thinking of something similar, although my strategy was meant to
be a bit different
- I would do the RDFa->RDF conversion using an online service. I guess
it would be possible to send a URI to either Fabien's service or pyRdfa
(well, I know about the latter) or others. In other words, a proper URI
for a test result could be minted. For example,
http://www.w3.org/2007/08/pyRdfa/extract?uri=http%3A//www.w3.org/2006/07/SWD/RDFa/testsuite/xhtml1-testcases/0012.xhtml
is a URI for test #12 with pyRdfa.
- I would create a full SPARQL query using that URI in a 'FROM'
- submit the SPARQL query to an online SPARQL site, like sparqler
http://www.sparql.org/
(I have created a SPARQL library to make such submission easier:
http://ivanherman.wordpress.com/2007/07/06/sparql-endpoint-interface-to-python/
that could come handy here. But there are others.)
This would have, in my view, several advantages:
- the test would be done on the latest versions. At least for pyRdfa I
know for a fact that the version running on the web is ahead of the
tar.gz distribution
- the same test could be done on different implementations easily with a
minor change in the target URI
- the test would rely on an external and, possibly, more reliable sparql
service.
As an example, you can send to sparqler the following query:
ASK
FROM
<http://www.w3.org/2007/08/pyRdfa/extract?uri=http%3A//www.w3.org/2006/07/SWD/RDFa/testsuite/xhtml1-testcases/0012.xhtml>
WHERE {
<http://example.org/node> <http://example.org/property> "chat"@fr .
}
to test pyRdfa and test #12.
Actually... I picked on #12 because it is also an example where the
python SPARQL goes wrong. Indeed, the sparqler result above is 'True'.
However, you test lists it as failing. For reference, here is the result
in Turtle generated by PyRDFa:
[[[
@prefix ex: <http://example.org/>.
ex:node ex:property "chat"@fr.
]]]
Which _is_ correct with the test above:-)
We will have something nice here.
