>                 URL: https://issues.apache.org/jira/browse/JENA-2145
>             Project: Apache Jena

>            Priority: Major

> 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.
