Re: validating Hydra documents (and ontologies)

Hi Markus, all,

The main idea behind RDFUnit is that vocabularies, ontologies, knowledge
bases and applications should be associated by test cases that assure a
basic level of quality.

For the first 2, we provide test generators that ensure the data are valid
in a CWA OWL setting and we convert automatically owl / rdfs axioms to test
cases (not full owl/rdfs support yet)
We also have generators for DSP and Resource Shapes constraints checking
(not 100% compliance either yet)

In addition to the automatic test case generation we support manual test
cases attached to vocabularies & ontologies that are loaded when ever we
test against a schema

e.g. we define in geo that the lat / lon should be in the range of [-90,90]
& [-180,180] and when ever someone uses -s geo as an option we load both
the automatic and the manual test cases in the validation process [1]
We did some initial work on manual test cases in a few vocabs like dbpedia,
geo, lgdo, skos, lemon & nif [2] that are available for everyone that uses
RDFUnit and loaded by default.
In the same manner you could define logical constraints for the hydra vocab
that would also be available by default when someone tests a hydra dataset.

I also updated the documentation a bit on the github wiki (there is a lot
more to add) but this should give you the basics
https://github.com/AKSW/RDFUnit/wiki

In addition, what we do atm, is to enable targeted validators that are
pre-configured with specific schemas and make domain specific validation
easier
https://github.com/AKSW/RDFUnit/wiki/LIB

The old demo is back online but I am working on a new version that I will
announce soon.
Let me know if you have any questions.

Best,
Dimitris
