Question: convert Jelly-with-quads to Turtle?

[persona0591]

Hi all!

Thanks for all your good work!

I have an N-Quads file, test.nq:

<https://example.org/> <http://www.w3.org/2000/01/rdf-schema#label> "Test"@en <https://example.org/my-graph> .

I have converted it to Jelly:

java -jar jelly-cli.jar rdf to-jelly test.nq > test.jelly

I'm now trying to convert the Jelly file to Turtle:

java -jar jelly-cli.jar rdf from-jelly --out-format ttl test.jelly > test.ttl

But I'm getting this error in return:

Jena RDF I/O exception: Quad in Triple output (...)

Is there a way to tell the Jelly CLI to convert only the triples?

This is how I do it in combination with Jena's Riot (--merge):

riot --merge --stream ttl test.jelly > test.ttl

Hey @persona0591 ! Thank you for using Jelly :)

Indeed, what you are trying to do is currently not supported, but it should be easy to fix.

My proposal is to add an option called --merge-graphs that does what you are requesting here. Then we should also update the error message that you received to mention the new option.

Does this sound good to you? I could try to add this small feature later today or over the weekend :)

Hi @Ostrzyciel Thanks for your response! Yes, your proposal sounds great! 🤗

@persona0591 the feature is merged and is now available in the dev builds: https://github.com/Jelly-RDF/cli/releases/tag/dev

These builds use the exact same options as the full releases, so this is safe for production use. We will make an 0.9.0 release in about a week.
