             Summary: SHACL alterntaive paths get turned into nested structures unnecessarily
                 Key: JENA-2008
                 URL: https://issues.apache.org/jira/browse/JENA-2008
             Project: Apache Jena
          Issue Type: Improvement
          Components: SHACL
    Affects Versions: Jena 3.17.0
            Reporter: Andy Seaborne
             Fix For: Jena 3.18.0


SHACLC parsing

{noformat}
shape ex:shape2 {
 targetNode = :WhatEver .
 ex:A|ex:B|ex:C datatype=xsd:integer .
}
{noformat}

produces

{noformat}
sh:path [ sh:alternativePath ( [ sh:alternativePath ( ex:A ex:B ) ] ex:C  )
{noformat}

which evaluates correctly but it could be {{sh:alternativePath ( ex:A ex:B ex:C  )}}.

Printing SHACLC (and SPARQL) paths ({{PathWriter}}) puts in {{()}} over-cautiously to get {{(ex:A|ex:B)|ex:C}}.
