range of idx:hasTarget and idx:hasSubIndex are wrong

[pchampin]

the current ontology says:

idx:hasTarget   rdfs:hasRange xsd:anyUri .
idx:hasSubIndex rdfs:hasRange xsd:anyUri .

This is incorrect. It means that the values of these properties should be literals with the datatype »sd:anyUri. And semantically, it would mean that the target / subindex is the URI itself, rather than the resource identified by that URI.

[pchampin]

The correct range for idx:hasSubIndex should obviously be idx:Index.

[pchampin]

For the range of idx:hasTarget, I see several options:

• we set it to ldp:RdfSource, because the intent is to point to RDF documents, but it then restricts our vocabulary to LDP- or Solid-managed resources, which seems overly constrained;
• we leave it unspecified, or set it to rdfs:Resource (which amounts to the same), but then it is overly unconstrained;
• we mint our own IRI for "any HTTP(s) resource that deferences to some RDF syntax" (I didn't find any matching term on LOV)

My preference would be to go for option two (unspecified) for the moment, and in parallel we create an erratum for the RDF WG, suggesting that the rdf: namespace should contain an IRI for the concept of RDF Source, and we eventually use this one.

[lecoqlibre]

Done both. Used option 2 regarding idx:hasTarget. Waiting for the erratum.

[pchampin]

Waiting for the erratum.

In fact I raised an issue instead.
