RE: State of SSN: comment on namespaces and urls

Thank you -- that is what I was asking about. The " a Turtle serialization of the ontology, etc. "  in particular.   In fact I checked myself on those particular specs you mention, but I wondered how  widespread this is.

By that I was referring to the HTML page to which you refer. 

Thanks!

I'm not sure what you call "a list of entities in the namespace and some documentation". In the linked data era we're now in, people expect to be able to dereference namespace uris and get meaningful information, meaning an HTML page for humans, some RDF serialization for machines.

That was not the case some years ago, but I think we typically publish ontology files at namespace uris nowadays, possibly using content negotiation so that people may see an HTML page, a Turtle serialization of the ontology, etc. depending on the Accept HTTP header. That is the case for the RDF, RDF Schema, OWL, Prov namespace URIs for instance.

Francois.
