Templates not working without TermType

[termontwouter]

When using rml:template to construct an expression value without a corresponding rml:termType, the triples in question are missing from the output, except when they result in a well-formed HTTP URI. According to the RML spec however, any resulting string (not NULL) needs to be mapped to its canonical RDF/XSD form.

Minimal example:

:mapping a rml:TriplesMap ;
  rml:logicalSource [
    # JSONPath root iterator over { "key": "value" }
  ] ;
  rml:subjectMap [ rml:termType rml:BlankNode ] ;
  rml:predicateObjectMap [
    rml:predicate <urn:example:typeless> ;
    rml:objectMap [ rml:template "key" ] ;
  ], [
    rml:predicate <urn:example:typed> ;
    rml:objectMap [ 
      rml:termType rml:Literal ;
      rml:template "key" 
    ] ;
  ] .

Output:

_:Blank1 <urn:example:typed> "key" .
