Codec proposal: N-Quads (RDF format)

Not sure if this is the right way to bring this up, but I'd like to propose adding a codec for N-Quads files. RDF is the graph data model for the semantic web, and although N-Quads is just one of many RDF serializations, it's commonly regarded as the lowest-level representation with the most regular structure and the least syntactic sugar.

In particular, N-Quads is the output format of the Universal Dataset Normalization Algorithm (URDNA2015) (also brought up in this issue). URDNA2015 is a big deal for the RDF world because it produces a canonical representation (ie two isomorphic datasets will produce the exact same serialized N-Quads string) that is required for all the digital signatures work that's starting to happen, and it's a representation that people will commonly want to hash!

This would also enable a natural interpretation of RDF datasets as IPLD objects, using an IPLD schema for the RDFJS data model with N-Quads as a custom representation.

I see this as a great concrete foundation for bringing the semantic web & decentralized web communities closer together. Is this the kind of codec we're open to adding? Would it be appropriate to open a pull request to table.csv?

Start by reviewing table.csv and the linked N-Quads, RDF, and URDNA2015 specifications to understand the proposed codec and whether this registry accepts it. Done means the proposal has a settled scope and, if accepted, the N-Quads codec is recorded in table.csv.
