Start of a GRDDL Test Suite

Hi DanC, RDF/XHTML TF,

I've started a (smallish for now) test suite for GRDDL implementations;
right now it includes only test for the simplest case, ie XHTML document
using the GRDDL profile:
http://dev.w3.org/cvsweb/2005/grddl-ts/

The tests are described in RDF, using the RDF schema that was developed
for the RDF Core Test Suite:
http://dev.w3.org/cvsweb/2005/grddl-ts/test-lists.rdf

Adding more tests to cover the other cases is simple enough, but before
getting to that I'd like to complete the simple test harness I've
started to develop:
http://dev.w3.org/cvsweb/2005/grddl-ts/testHarness.py

You invoke it à la:
 python testHarness.py --<action> "/home/dom/dev.w3.org/2005/grddl-ts/gleanWrapper" file:///home/dom/dev.w3.org/2005/grddl-ts/test-lists.rdf
where <action> can be "run" or "update"

(I've written a wrapper for glean.py and one for the XSLT-servlet based
demo; they're straightforward shell scripts that takes a URI as sole
argument; I'll probably add a wrapper for a RAP-based GRDDLer later on)

"update" is implemented and makes it so that local files matching the
output URIs be generated from the processor given in argument.
"run", which is supposed to be the interesting part, only outputs the
results of GRDDLing the various input files; it should instead compare
the said output with the referenced output documents given in the tests
list. 

DanC, you mentioned using cwm to do this: would this imply using
delta.py as distributed in the cwm tarball? If so, I'm not sure whether
this should be done by importing the said python code, or by using it as
a command line tool; if the latter, it looks like delta.py doesn't
return a different code depending on whether there was any diff or not,
making it a bit more painful to use in this context. Any suggestions?

(in the end, I'd like the test harness to output an EARL description of
what tests failed/succeeded, but that's probably easy enough to code
once the diff is implemented)
