Incorrect SPARQL Exprs when joining TriplesMaps with different reference formulations #6

Closed Aklakan closed 1 year ago

Aklakan commented 1 year ago

The TriplesMapProcessorRml incorrectly resolves all expressions against a RefObjectMap's child context . If the child of a join uses JSON and the parent uses XML then json functions will be applied to the XML data:

[] <http://semweb.mmlab.be/ns/rml#source>  "/data/shared/STOPS.xml" ;
   <https://w3id.org/aksw/norse#rml.output>  ?s2}
BIND(<https://w3id.org/aksw/norse#json.get>(?s2, "stop_id") AS ?jc0)
