Wikidata RDF export uses wikiba.se/ontology as ontology base. However, http://wikiba.se/ontology does not lead to any page. It should lead to OWL description of the ontology or at least to some page that describes it.

Wikiba.se is built on sculpin which I have no idea how to make do redirects. Does it actually run sculpin or sculpin just being used as page generator and there's some real webserver we could use to make redirects?
Comment Actions
It is currently on some mass web hosting service. Someone told me its static, i.e. generated output only. See also T99531 and T99530. So if you want it fast talk to @JeroenDeDauw.

Currently the webserver only has the Sculpin output. PHP is installed on it, so we can make use of PHP if we want.
This ticket and https://github.com/wmde/Wikiba.se/issues/32 mention the need for redirects. It is not clear to me where to these redirects need to point. Is the OWL description of the ontology already available somewhere?
Comment Actions
@JeroenDeDauw right now the ontology lives at docs/ontology.owl in Wikibase repo. We need to figure out two things:
- How to expose it to the outside as an URL
- How to make versions of it, so we could have ontology-1.0.owl, ontology-1.1.owl etc.
I think probably the best way to do it is this:
- Put current ontology under http://wikiba.se/ontology/ontology-1.0.owl as static file (just copy it)
- Make a 302 redirect from http://wikiba.se/ontology to http://wikiba.se/ontology/ontology-1.0.owl (important - not 301 since it will always point to the latest one)
- Manually add new versions each time we change something in the ontology and move redirects.
This involves some manual work, and I'm not sure how to make redirects work in Sculpin, so if you have a better idea I'd be glad to hear.

Sounds like a reasonable approach to me.
AFAIK you cannot do 302 redirects with Sculpin. Then again, Sculpin does not prevent you from doing redirects on your own, so we could create some trivial PHP script that does it.
Comment Actions
Perhaps a simple server config file (like .htaccess) should work. Not sure if that is supported by the hosting provider though.
Comment Actions
.htaccess would definitely work but I don't know how this is hosted and where to put it. @JeroenDeDauw, any insights on this?

Redirects appear to be working as intended. owl file is broken, fix in https://github.com/wmde/Wikiba.se/pull/39
