/ns/oa/index.* do not resolve #359

Closed azaroth42 closed 7 years ago

azaroth42 commented 7 years ago

Going to https://www.w3.org/ns/oa/ presents an HTML list of the available serializations of the vocabulary, as discussed previously.

However currently clicking on the links does not resolve to the serializations, instead it goes back to the same HTML page.

Seems like a configuration issue of the server?

The right URI-s for the namespace files (at this moment) are

https:/www.w3.org/ns/oa http://www.w3.org/ns/oa.{html,ttl,jsonld,owl,rdf}

and there is an oa.var file:

URI: oa

URI: oa.html
Content-Type: text/html

URI: oa.rdf
Content-Type: application/rdf+xml; qs=0.4

URI: oa.ttl
Content-Type: text/turtle; qs=0.6

URI: oa.jsonld
Content-Type: application/ld+json; qs=0.5

URI: oa.json
Content-Type: application/json; qs=0.4

to ensure conneg.

In other words, the HTML file seems to be the problem child:-(

Indeed, content negotiation works 

OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
URL OAURL = new URL("https://www.w3.org/ns/owl.ttl");
InputStream oais = OAURL.openStream();
OWLOntology ontologyOA = manager.loadOntologyFromOntologyDocument(oais);

Before, I used the following code receiving the following error.

OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
URL OAURL = new URL("https://www.w3.org/ns/oa/index.owl");
InputStream oais = OAURL.openStream();
OWLOntology ontologyOA = manager.loadOntologyFromOntologyDocument(oais);

Thanks for pointing out the url http://www.w3.org/ns/oa.{html,ttl,jsonld,owl,rdf}

That must be changed, to be updated
