While working on data in JSON-LD and turtle, I found that SPARQL queries are producing incorrect results for JSON-LD while correct results for turtle format.
The following query produces 12 rows for 4 separate datasets in JSON-LD for a SWRL rule while it produces 9 rows for the same datasets in turtle syntax. For example, out of 12 rows the triple indicating http://sampledata.com/id_3 ex:back http://sampledata.com/id_2 should not be inferred.
One of the reasons may be incorrect generation of blank nodes for JSONLD source data. For example, the following SPARQL query shows that instead of generating 4 distinct blank nodes, same blank node 'b0' is generated for each of the distinct datasets.
All the test queries were run on stardog-7.0.1 and the stardog-studio.
I have attached the ontology, 4 distinct datasets in both JSONLD and turtle format, and 4 screenshots of the above results from the queries.testcases-jsonld-vs-turtle.zip (129.1 KB)
