Re: [rdf4j-dev] SHACL and checking rdfs:Resource

["Håvard M. Ottestad" <hmottestad@xxxxxxxxx>]

Hi Bart,

It should match everything as you say. And that might even work if you use it with the RDFS reasoner. Which I have not tried!

There is some rudimentary support for rdfs as part of the shacl standard, namely support for rdfs:subClassOf. Which is implemented. I don’t know what they think about rdfs:Resource though. 

In practice, right now, I think it would only match those subjects with explicit type for rdfs:Resource.

Hi,

 

A quick question about the SHACL validator in 3.0-snapshot, or SHACL In general

I’ve noticed that the new EU DCAT-AP 1.2 has a few shapes with a class constraint like

 

sh:path …

sh:class rdfs:Resource

sh…

 

which IMHO does not make sense (since rdfs:Resource is, well, anything…),

but the validator does seem to generate a violation if this class is not explicitly set.

 

So would it be appropriate to just ignore this rule in the validator ? Or am I missing something here ?

 

 

Best regards

 

Bart
