Stefan Bischof created JENA-2344:
------------------------------------

             Summary: Invalid JSON-LD context generated for CONSTRUCT query
                 Key: JENA-2344
                 URL: https://issues.apache.org/jira/browse/JENA-2344
             Project: Apache Jena
          Issue Type: Bug
          Components: Fuseki, JSON-LD
    Affects Versions: Jena 4.1.0
            Reporter: Stefan Bischof


For URIs having a slash / in the fragment identifier an invalid JSON-LD context is generated.

 

Steps to reproduce:
 # Add a triple with with a slash in the fragment identifier to some graph, e.g., "[] <https://smart-data-models.github.io/data-models/terms.jsonld#/definitions/category> "meter" .
 # Retrieve the triple in a CONSTRUCT query, e.g., CONSTRUCT WHERE \{ ?s ?p ?o }
 # Set "Accept" header in HTTP call or "Content-Type (Graph)" in Fuseki WebUI
 # The context at the end of the response includes the invalid key "/definitions/category"

 
{
  "@graph" : [ ],
  "@context" : {
    "/definitions/category" : {
      "@id" : "https://smart-data-models.github.io/data-models/terms.jsonld#/definitions/category"
    }
  }
}
 
{color:#24292f}{color:#24292f}Although I couldn't find a formal grammar for JSON-LD, the python parser I used and the parser on the JSON-LD playground [https://json-ld.org/playground/] did not accept this: {color}{color}jsonld.SyntaxError: Invalid JSON-LD syntax; term in form of IRI must expand to definition.
