epos-dcat-ap_shapes update test on dcat:accessURL #302

Open sgrellet opened 6 years ago

sgrellet commented 6 years ago

Testing on WP15 files, Shacl playground complains about dcat:accessURL pointing to a epos:WebService; However a epos:WebService; is a rdfs:subClassOf rdfs:Resource ; it seems the subtyping is not taken into account. => Need to add [ sh:class epos:WebService; ]

to the following test

sh:property [ sh:path dcat:accessURL ; sh:or ( [ sh:class rdfs:Resource ; ] [ sh:class hydra:Operation ; ] [ sh:datatype xsd:anyURI ; ] ) ; sh:minCount 1 ; ] ;

@sgrellet If the type of Distribution is WEB SERVICE, dcat:accessURL refers to the Operation of the Web Service to which the Distribution conforms; while dct:conformsTo refers to the Web Service.

I corrected your WP15 RDF file.

@rpaciello the pattern dcat:accessUrl -> webservice/operation and explicitely copy/pasting the hydra:entrypoint value into the hydra:template of the operation is weird to us

indeed a webservice having 1 entrypoint can have several hydra:operation(s). That's the case for all OGC services (don’t have time today to type it in our ttl).

In the proposed approach you allow to provide a different entrypoint value through the hydra:template (or copy/pasting that value could cause an issue for maintenance).

Best would be, for us, at the client level to 'concatenate' hydra:entrypoint with information from hydra:template for the operation your client wants to activate

But we’ll talk about this afterwards the demonstrator :)

I agree with this change. By using the relative path in Operation we would also avoid duplications when the same Webservice is deployed in multiple sites. Indeed a good topic for discussions in Barcelona!
