Description

TDB1 converts small xsd:long literals, e.g. "1"^<xsd:long> to xsd:integer. This behavior is specific to TDB1. Even though that might be acceptable in most cases, it breaks validation of SHACL {{ sh:dataType xsd:long ;}} constraints. The following test demonstrates the issue:

    @Test public void longLiterals() {
        DatasetGraph dsg = TDBFactory.createDatasetGraph();
        Quad quad1 = SSE.parseQuad("(quad <g> <s> <p> \"1\"^^<http://www.w3.org/2001/XMLSchema#long>)");
        assertEquals(XSDDatatype.XSDlong, quad1.getObject().getLiteralDatatype());
        dsg.add(quad1);

        Quad quad2 = dsg.find().next();
        assertEquals(XSDDatatype.XSDlong, quad2.getObject().getLiteralDatatype());
    }
