Executing SHACL-AF

[Christophe Debruyne]

Dear all,

I tried looking at previous messages for clues but to no avail.

I was wondering whether I am forgetting something in order to support SHACL-AF.

The following shape works with pyShacl.

<#USPHONESHAPE>

    a sh:NodeShape ;

    sh:target [

        a sh:SPARQLTarget ;

        sh:prefixes <#PREFIXESFORSPARQL> ;

        sh:select """

            SELECT ?this WHERE {

                ?this a vcard:Individual .

                ?this vcard:hasAddress ?address .

                ?address vcard:country-name "USA" .

            }

            """ ;

    ] ;

    sh:property [

        sh:path ( vcard:hasTelephone rdf:value ) ;

        sh:pattern "^\\(\\d{3}\\)\\s\\d{3}-\\d{4}$" ;

    ] ;

.

Topbraid's shaclvalidate.bat doesn't pick up on that shape, however. I am using the following command:

shaclvalidate.bat -datafile .\output.ttl -shapesfile .\output.ttl

I understood that shacl-af was supported and threads in the group do allude to sh:SPARQLTarget and sh:select being used. Am I missing something?

With my best regards,

Christophe Debruyne

To speed up finding the cause of this, would you mind sending the complete file, or at least a minimal snippet that allows me to run this locally? I see nothing obviously wrong, but the devil may be in the details.

Dear Holger,

Thanks. Creating the minimal files helped me spot the problem. The working group's notes [1] contain a mistake: 

sh:declare [ sh:prefix "ex" ; sh:namespace <http://example.com/ns#> ; ] .   

should be

sh:declare [ sh:prefix "ex" ; sh:namespace "http://example.com/ns#"^^xsd:anyURI ; ] . 

I used the correct syntax in the other folder (probably copied from the shacl recommendation).

Yes! I spotted the same mistake (*my* mistake as editor of this doc) and fixed it earlier today.

Refresh your browser :)

Thanks
