Is it needed to explicitly import sh?

 

Or is it like rdfs, rdfs, owl, xsd etc.

 

(I used to import dash but given that issue…etc.)

In general, owl:imports are a good thing. They make the semantics of the used resources more explicit and transparent. If we skip them here, where would this end: use skos:Concept without importing SKOS Core? Makes no sense to me.

More like:

 

Is sh in the league of xsd/rdf/rdfs/owl (not imported)

 

Or in the league of others being imported explicitly

My view…sh would fit well in that list of languages (xsd, rdf, rdfs, owl, …) that are handled without explicit import…

 

???

 

Counterargument?

What does it even mean to be "handled". In all TopBraid tools, there is a hidden automated import of system triples including XSD, RDF etc. Without that, no forms and other algorithms would work. Algorithms wouldn't even know that owl:Class rdfs:subClassOf rdfs:Class. The design of OWL in this respect is a failure, and I believe they don't want people to import the metamodel because it broke some OWL DL algorithms with the introduction of metaclasses. Having to implement some special hidden graph is ugly.

Hi Holger

 

I see the issue.

 

So reformulated my question is:

 

Is shacl import also automated now (like eg rdf)?

(It seems not, since deleting the import also deletes the shacl tab)

 

If not, should be it be? (consistently, since it is also a basic language vocab)

Or not, because it is not that essential like rdf(s) etc. ie not breaking code etc.)

 

 

But generalizing I see you point that ‘being essential’ depends in the end on what you want to do with it….(forms etc.)

(and explicit import only works if the stuff imported is perfect…)

 

All in all, I think, shacl getting more and more important, it would be best to automatically load it.

(in other words: TBBC being by default a RDF/RDFS/OWL/SHACL-tool).

 

For now, I’ll keep the sh imports explicitly in…..

 

Gr michel

Hi Michel,

If users want SHACL then in TBC use File, New, SHACL Shapes file and there’s a checkbox to decide initial imports of dash or pure SHACL.  

If users want RDFS/OWL then use File, New, RDF File. 

TBC users have control.

Cheers,
David

Yes in case of ‘choice’ checkbox is fine

However we also have scenarios where both OWL and SHACL are relevant (say for use cases involving inference and verification).

Or in future where we might want to go shacl-only (blog irene…).

 

Those scenarios would benefit from automatic shacl import….
