Stefan Bischof commented on JENA-2344:
--------------------------------------
Thank you for your quick reaction!
And - after further testing - this is indeed fixed by version 4.5.0. Apparently
I still had version 4.2 in my path although I ran the arq.bat from the 4.5.0
directory.
The current version doesn't try to abbreviate the URI in the context. That also
solves the problem. Although I would have preferred to have in in the context
with a "meter" key.
Follow-up question: is it possible to configure Fuseki with a JSON-LD context
URL which it then uses to compact the JSON-LD response?

> Key: JENA-2344
> URL: https://issues.apache.org/jira/browse/JENA-2344
> Project: Apache Jena
> Issue Type: Bug
> Components: ARQ, Fuseki, JSON-LD
> Affects Versions: Jena 4.1.0, Jena 4.5.0
> Reporter: Stefan Bischof
> Priority: Major
>
> 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"
> {
> "@id" : "_:b0",
> "/definitions/category" : "meter",
> "@context" : {
> "/definitions/category" : {
> "@id" :
> "https://smart-data-models.github.io/data-models/terms.jsonld#/definitions/category";
> }
> }
> }
>
> 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: jsonld.SyntaxError:
> Invalid JSON-LD syntax; term in form of IRI must expand to definition.
> I could replicate the same behaviour on the cli with ARQ 4.5.0.
