The repo is pretty clear on its intentions to not be a language-specific format:
> Development Plans
> I fully intend to develop JDF.jl into a language neutral format by version v0.4. However, I have other OSS commitments including R's {disk.frame} and hence new features might be slow to come onboard. But I am fully committed to making JDF files created using JDF.jl v0.2 or higher loadable in all future JDF.jl versions.
It's beyond v0.4 and at v0.5.1 right now so it seems delayed, but the repo describes intentions to be a language-neutral format after the dust settles. I think we're just taking a snapshot too early in the timeframe to really know what this project is truly all about. And given that the author is an OSS dev for multiple languages, this intention makes a lot of sense.
