Implement a simple Jelly parser

[Ostrzyciel]

Make a minimal Jelly parser implementation.

Feature list – up for discussion:

• TRIPLES and QUADS physical types
• Emitting the triples/quads through a simple functional interface
• RDF1.1 only, no quoted triples

Non-goal: pretty or super-performant code. Let's just make it work.

Resources:

• short guide https://jelly-rdf.github.io/dev/user-guide/#implementing-jelly
• Python impl for reference https://github.com/Jelly-RDF/pyjelly/tree/main/pyjelly/parse
• Spec: https://jelly-rdf.github.io/dev/specification/serialization/
• Round-tripping test cases (can be turned into .jelly files with jelly-cli): https://github.com/Jelly-RDF/pyjelly/tree/main/tests/e2e_test_cases
  • Let's not worry about conformance tests at this moment, it would be too complex
• jelly-cli for RDF->jelly->RDF conversion and debugging: https://github.com/Jelly-RDF/cli

Awesome work! As I have written in this feature request it would be great to have Jelly support in Oxigraph!

Hi @MadsHolten, thanks for your interest and the feature request! :) Much appreciated.

I replied with details on the development status here: oxigraph/rio#156

I also opened a separate issue for the integration: #10

In short, the Rust implementation is currently community-led, so you (and anybody else) are welcome to contribute. If you have a commercial interest in this, we would be happy to discuss it (piotr@neverblink.eu) – we can accelerate the implementation of this feature, and of the library in general.
