[Obi-devel] new purl(sort of) based obi identifiers

[Alan Ruttenberg]

I've uploaded a file: http://groups.google.com/group/obi-developer/
web/newids.tgz

Which when unpacked should have versions of all the files with the
new identifiers.
You should be able to open obip.pprj in the unpacked "newids" folder
and review the file.

It would probably be good to have a couple of people do a sanity
check. I've done as much as I can to ensure that it looks ok, adding
labels where necessary. Note that I entered a tracker item with a
(long) list of terms that don't have a curation_status field.

The OWL is quite ugly, with the relations now identifiers, but things
seems to display properly in protege. (I have an idea of how one
might make the OWL look better, by using XML entities - for a later
date).

Perhaps in the obi-devel meeting tomorrow we can give a final go-
ahead for the new scheme.

After discussion with several people, including Chris Mungall, and
mail to the obo coordinators list not pulling back any objections,
the OBI URIs (for all of class, properties, and instances) uniformly
look like e.g.

http://thing.obofoundry.org/obo/OBI_0100000

thing.obofoundry.org has(will) have a dns entry that points to
purl.org. This gives us an extra layer of insulation from changes
that might happen in the future to purl.org - in that case we can use
some other redirection service.

The url for the ontology would be http://thing.obofoundry.org/obo/
obi.owl

Note that you need to edit one line before opening the files - in
obip.owl, edit the line tha now says:
xml:base="file:///Users/alanr/repos/obi/branchDevelopment/trunk/
newids/">
to instead use the path of newids folder created when you untar the
file.

Also, although I think you should see the labels when you open using
the obip.pprj file, if you don't, ask Melanie for instructions on how
to make them visible (I don't want to repeat the instructions here)

I just uploaded a new tar file with minor fixes.

What changes in purl.org are you expecting? It seems like you trust the
stability of thing.obofoundry.org more than the stability of purl.org, which
is quite surprising.

One never *expects* changes. Stability isn't quite the right word for
thing.obofoundry.org - it's just a dns entry. Moreover we can
prominently advertise that it redirects to purl.org (unless it stops
doing that). So all that needs to be done is to ensure that the
domain name lives on, which is doable (we would seek some sort of
insurance/endowment).

Anyways, that's the thinking.
