Possibility to "materialize" blank nodes

[leipert]

I have a document with blank nodes. I want each blank node to be converted to a resource.

e.g.

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix sh: <http://www.w3.org/ns/shacl#> .
<urn:example:shape>
    a sh:NodeShape ;
    sh:property [
        sh:datatype xsd:integer ;
        sh:message "ID must be a number" ;
        sh:name "ID" ;
        sh:path <urn:example:id>
    ]
.

should be converted to

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix sh: <http://www.w3.org/ns/shacl#> .
<urn:example:shape>
    a sh:NodeShape ;
    sh:property <urn:generated:A924E218-632F-4328-8D52-EFC48D784C5D>
.

<urn:generated:A924E218-632F-4328-8D52-EFC48D784C5D>
        sh:datatype xsd:integer ;
        sh:message "ID must be a number" ;
        sh:name "ID" ;
        sh:path <urn:example:id>
.

The CLI should provide a parameter for an URI template urn:example:{uuid} where {uuid} will be replaced with an uuid. Have a look into uuidgen to generate uuid's in the command line.

Thank you for your hard work.

useful links regarding blank nodes:

• https://www.insight-centre.org/sites/default/files/publications/blank_nodes_jws.pdf
• https://www.w3.org/wiki/BnodeSkolemization
• http://richard.cyganiak.de/blog/2011/03/blank-nodes-considered-harmful/

so real skolemization is out of scope I think, but also just a simple materialisation can be useful.
