--------------------------------------

             Summary: shaclc serialization of datatypes should be shorter
                 Key: JENA-2145
                 URL: https://issues.apache.org/jira/browse/JENA-2145
             Project: Apache Jena
          Issue Type: Improvement
            Reporter: Vladimir Alexiev


https://github.com/euBusinessGraph/eubg-data/blob/master/model/ebg-shapes.shaclc includes the following:
{noformat}
  skos:altLabel            xsd:string|rdf:langString !pattern="^ | $| {2}" [0..*] .
{noformat}
This is output more verbosely as:
{noformat}
    skos:altLabel ! pattern="^ | $| {2}" datatype=xsd:string | datatype=rdf:langString .
{noformat}

The shorter notation is allowed according to https://w3c.github.io/shacl/shacl-compact-syntax/#rule-propertyType:
"propertyType: If ?iri is one of the RDF datatypes supported by SPARQL 1.1 (such as xsd:string) then produce a triple ?property sh:datatype ?iri, otherwise ?property sh:class ?iri."

Jena already checks whether the IRI is a known datatype and otherwise outputs "class=". So it should be a simple matter to implement the shorter notation.
