Description

Data:

:s1 :p "langtag"@en .
:s2 :p "simple string" .
:s3 :p "datatype string"^^xsd:string .
:s4 :p "not a string"^^xsd:anything .

Output RDF.1.1 :

  <literal datatype="http://www.w3.org/2001/XMLSchema#anything">not a string</literal>
  <literal>datatype string</literal>
  <literal>simple string</literal>
  <literal xml:lang="en">langtag</literal>

using the RDF 1.1 guidance that rdf:langString should not be in output and plain literals are preferred to explicit xsd:string.

Incorrect output Jena 3.0.0:

  <literal datatype="http://www.w3.org/2001/XMLSchema#string">simple string</literal>
  <literal xml:lang="en" datatype="http://www.w3.org/1999/02/22-rdf-syntax-ns#langString">langtag</literal>
  <literal datatype="http://www.w3.org/2001/XMLSchema#anything">not a string</literal>
  <literal datatype="http://www.w3.org/2001/XMLSchema#string">datatype string</literal>

Output Jena 2.13.0 (RDF 1.0):

  <literal>simple string</literal>
  <literal xml:lang="en">langtag</literal>
  <literal datatype="http://www.w3.org/2001/XMLSchema#anything">not a string</literal>
  <literal datatype="http://www.w3.org/2001/XMLSchema#string">datatype string</literal>
