Re: Starting with SHACL-JS

I'm using now the SHACL API.

I copied the example JavaScript-based Constraint in 6.1 section from
https://www.w3.org/TR/shacl-js/

The Data Graph has 3 instances (2 wrongs).
========
@prefix ex:   <http://www.test.com/ns#> .

ex:ValidCountry a ex:Country ;
    ex:germanLabel "Spanien"@de .

ex:InvalidCountry a ex:Country ;
    ex:germanLabel "Spain"@en .

ex:InvalidCountry_2 a ex:Country ;
    ex:germanLabel "Spain"@pt .
========

The JavaScript function is:
========
function validateGermanLabel($this) {
    var results = [];
    var p = TermFactory.namedNode("http://example.org/ns#germanLabel");
    var s = $data.find($this, p, null);
    for(var t = s.next(); t; t = s.next()) {
        var object = t.object;
        if(!object.isLiteral() || !object.language.startsWith("de")) {
            results.push({
                value : object
            });
        }
    }
    return results;
}
========

And, the Shape Graph is:
========
@prefix sh:   <http://www.w3.org/ns/shacl#> .
@prefix xsd:  <http://www.w3.org/2001/XMLSchema#> .
@prefix rdf:  <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix ex:   <http://www.test.com/ns#> .
@prefix dash: <http://datashapes.org/dash> .
@prefix sf:   <http://www.opengis.net/ont/sf#> .
@prefix rdfs:  <http://www.w3.org/2000/01/rdf-schema#> .

ex:LanguageExampleShape
    a sh:NodeShape ;
    sh:targetClass ex:Country ;
    sh:js [    # _:b1
        a sh:JSConstraint ;   # This triple is optional
        sh:message "Values are literals with German language tag." ;

        sh:jsLibrary [ sh:jsLibraryURL "
http://54.201.29.21/shapes/SHACL-JS-W3C-Javascript.js" ] ;

        sh:jsFunctionName "validateGermanLabel" ;
    ] .
========


All files can be found in http://54.201.29.21/shapes/.

I use the following command to validate the Data Graph:

sudo sh  shacl-1.3.1/bin/shaclvalidate.sh -datafile
myExamples/SHACL-JS-W3C-DataGraph.ttl -shapesfile
myExamples/SHACL-JS-W3C-ShapeGraph.ttl


But in the result it appeared as valid.
The 2 violations did not appear in the Data Graph.


[ a       <http://www.w3.org/ns/shacl#ValidationReport> ;

  <http://www.w3.org/ns/shacl#conforms>

          true

] .

I can't see where my error is, if it is in any of the files, in the command
executed via terminal or if it can be my installation of the SHACL API.

Hugs,
