-------------------------------------
Hi [~stefanbis]
I can't reproduce this for Fuseki 4.5.0.
It does fail for 4.4.0 and earlier versions - writer was writing JSON-LD 1.0
where jena uses jsonld-java but 4.5.0 switched to JSON-LD 1.1 output.
Maybe results got cached somewhere? Or it is
Fuseki 4.5.0:
{noformat}
curl -g --header 'Accept: application/ld+json' -d 'query=CONSTRUCTWHERE {?s ?p
?o}' http://localhost:3030/ds
{noformat}
{noformat}
{
"@id": "_:b0",
"https://smart-data-models.github.io/data-models/terms.jsonld#/definitions/category":
"meter"
}
{noformat}
which is produced by Titanium-jsonld which provides JSON-LD 1.1. Similarly CLI
{{riot --out JSON-LD D.ttl}}.
{noformat}
riot --version
Jena: VERSION: 4.5.0
Jena: BUILD_DATE: 2022-05-01T13:58:04Z
{noformat}
[The JSON-LD 1.0 playground|https://json-ld.org/playground/1.0/] says the
{{@context}} version is legal JSON-LD 1.0. This is not the first example we've
had when JSON-LD 1.1 is incompatible with JSON-LD 1.0. JSON-LD 1.1 should have
been called JSON-LD 2.0.
> 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: 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.
