Creating NodeShapes with connected PropertyShapes

[StephanLupp]

Hello Marco,

You are a live-safer, this is exactly what I was looking for.
Thanks for the very quick response and good example how to connect this. I never considered that "RDFPropertyConstraint" is used for this.

I do hope that we can contribute further, we will continue to use the library and post questions that we find or oddities that we notice.

Best Regards
Stephan

Hi Stephan,
here is an implementation of the example turtle file showing usage of constraints and targets:

var shapesGraph = new RDFShapesGraph();

var nodeShape = new RDFNodeShape(new RDFResource("ex:PersonShape"));
nodeShape.AddTarget(new RDFTargetClass(new RDFResource("ex:Person")));
nodeShape.AddConstraint(new RDFPropertyConstraint(new RDFResource("ex:PropertyShapeSSN")));
nodeShape.AddConstraint(new RDFPropertyConstraint(new RDFResource("ex:PropertyShapeWorksFor")));
nodeShape.AddConstraint(new RDFClosedConstraint(true).AddIgnoredProperty(RDFVocabulary.RDF.TYPE));

var propertyShapeSSN = new RDFPropertyShape(new RDFResource("ex:PropertyShapeSSN"), new RDFResource("ex:ssn"));
propertyShapeSSN.AddConstraint(new RDFMaxCountConstraint(1));
propertyShapeSSN.AddConstraint(new RDFDatatypeConstraint(RDFModelEnums.RDFDatatypes.XSD_STRING));
propertyShapeSSN.AddConstraint(new RDFPatternConstraint(new Regex("^\\d{3}-\\d{2}-\\d{4}$")));

var PropertyShapeWorksFor = new RDFPropertyShape(new RDFResource("ex:PropertyShapeWorksFor"), new RDFResource("ex:worksFor"));
PropertyShapeWorksFor.AddConstraint(new RDFClassConstraint(new RDFResource("ex:Company")));
PropertyShapeWorksFor.AddConstraint(new RDFNodeKindConstraint(RDFValidationEnums.RDFNodeKinds.IRI));

shapesGraph.AddShape(nodeShape);
shapesGraph.AddShape(propertyShapeSSN);
shapesGraph.AddShape(PropertyShapeWorksFor);

It is of course possible to contribute to the library: posting questions, signalling issues, requesting new capabilities, also submitting PRs for targeting bugs or delivering new features.

Let me know if this coding example clarifies your doubts about usage of the library.
Regards,
marco
