JSON2RDF
Hi all,
just wanted to let you know that in addition to CSV2RDF we've now
published JSON2RDF:
https://github.com/AtomGraph/JSON2RDF
It's a Jena-based generic JSON2RDF converter which reads JSON and
writes streaming N-Triples output.
Such output is well-suited for further transformation with SPARQL
CONSTRUCT, for vocabulary (re-)mapping, URI building, datatype fixing
etc.
I think the algorithm is similar to JSON-LD but I'm not too sure. In
any case, no @context is necessary as JSON2RDF accepts arbitrary JSON.
I see JSON2RDF+CONSTRUCT as a more flexible alternative to
JSON-LD+@context when it comes to lifting JSON data to RDF.
Hope it can be useful.

If you have sample data, we can quickly find out :)

I've just added a reference to JSON2RDF in the JARQL Readme.
The projects share the limitation of loosing the order of Arrays. But does JSON2RDF support nested arrays?
It would be nice to compare the RDF models.
Cheers,

Yes indeed! I’m considering adding built-in SPARQL support as well.
Do you know how widely it is used?

Yes indeed! I’m considering adding built-in SPARQL support as well.
Do you know how widely it is used?

Hi Martynas,
This sounds very similar to JARQL which applied the TARQL idea to JSON in allowing to run CONSTRUCT queries on JSON data.
See: https://github.com/linked-solutions/jarql
