There have been discussions of, e.g. Skolemization of existing resources,
and those transformations are destructive.

Reducing to RDF would not change the ontological commitment, but would lose
information. In any case such a transformation should not entail minting
new Uris for all resources. In addition, I question the value of
transforming the ontologies in this way, given the disadvantages of not
encouraging a uniform, author provided view on the resources. The OWL
resources are SPARQL friendly enough to build onto bee displays. If you
look at the bottom of the page there are links to see the SPARQL queries
used to construct the pages. A more constructive effort, in my opinion,
would be to build SPARQL parser extensions along the lines of TERP that
make it easier to query the ontology as it is.

Conformance to what? To the OWL Spec? Yes, I believe it does, through the
OORT and Jenkins build tools, but I'll leave it to Chris to detail that. If
there is something you are looking specifically for I expect it could be
provided. Or you could collaborate with us to build such services. I
believe that collaboration towards building a stronger single distribution
is a much better way to spend effort, in the long run.

We are moving towards completely using Web standards. Eventually, we will
have all OBO ontologies available at
. This, and other information about deployment is in
http://obofoundry.org/obo/id-policy.shtml, which describes what we are
 trying to put in place. Again, we are making progress in this effort, but
help could certainly be used. Chris pays attention to where ontologies are
before they arrive at their documented location. I attend to ensuring that
once there they behave as expected according to web standards. If you look
at http://www.ontobee.org and select an ontology there should be metadata
about where the ontology was downloaded from to get it into Ontobee.

Indeed. They are not where you would expect to find them.

There are two sparql endpoints at the moment, each with different
approaches. We are working toward deciding on and documenting expected
behavior and then ensuring we can provision them well enough to stand up to
regular use.

Understand also that we are coming to the end of a multi-year effort to
regularize our URIs, defining a proper OWL translation of OBO, and
providing a new BFO to be the basis for these ontologies. We are not quite
finished. I would be most comfortable publishing a stable endpoint once
this transition was over. Again, assistance in deploying mirrors and in
helping with all the various loose ends needed before the resource can be
considered stable would be very much welcomed.

http://sparql.obo.neurocommons.org/ intended to serve ontologies using the
legacy URIs (needs to be reviewed - hasn't been in a while.)
http://sparql.obodev.neurocommons.org/ intended to serve ontologies using
the current URIs (same as above)
http://sparql.hegroup.org/sparql serves the ontobee server (not meant for
wide consumption, but useful for prototyping)

Members of HCLS who wish to assist with maintenance of the Neurocommons
endpoints would be welcomed. Once they are reviewed and brought up to date
on which ontologies they load, the Neurocommons RDF Bundling system will
provide an addition distribution mechanism for creating mirrors.

So Michel, and other HCLS users, consider this an invitation: The OBO
Foundry is very close to providing a stable, well thought through process
for semantic web deployment of OBO ontologies. We could very much use
technical support in finishing a number of technical loose ends, in
providing tools that build on these efforts, and on making it easy to
access existing endpoints or provide mirrors of the content. If there is
sufficient interest in this within the group perhaps Chris and I can
schedule a time when we could meet with those interested and see what the
possibilities are.
