I’ve got some files containing RDF data serialized as json-ld. Is there a simple way to add json-ld data to a stardog database?

Thanks,  
Peter

Hi Peter,

Assuming your files have a .jsonld or .json extension, `stardog data add` should accept them as-is. If that’s not the extension, you _might_ be able to pass in `--format jsonld` but I’m not 100% sure on that.

Hi Peter,

If you are using the Java API, you can format it while streaming it. I couldn’t make it work through the web API.

aConn.add().io().format(RDFFormat.RDFXML).stream(ontologyInputStream);

Hope that helps,  
Charbel

That's exactly what I wanted to do, but my version (4.1.1) complains:  
`No known format matches the file: C:\Users\pneorr\Desktop\scratch-jsonld\default.json`

The online docs don't list jsonld as a supported format. ☹  
[404 | Stardog Documentation Latest](https://docs.stardog.com/man/data-add.html)

Adding --format JSONLD flag causes a different error:  
`'JSONLD' is not a valid RDF format identifier. Acceptable format strings are NTRIPLES, RDF/XML, TURTLE, PRETTY_TURTLE, TRIG, TRIX, N3, NQUADS.`

Adding --format JSON flag does something similar:  
'JSON' is not a valid RDF format identifier. Acceptable format strings are NTRIPLES, RDF/XML, TURTLE, PRETTY\_TURTLE, TRIG, TRIX, N3, NQUADS.

My short term fix was to use protege to save as turtle. (gag)

Hmm, if changing the filename to a `.jsonld` extension doesn’t do the trick then I’m not sure you could have done it any other way in 4.1.1. I can confirm that this bug has been fixed some time between then and 4.2.4. At least the `.json` part. Apologies for the confusion!
