IPFS-LD

The power of the semantic web is worth considering. While it hasn't really "taken off," it's TRTTD when it comes to data structuring.

@msporny created the wonderfully simple JSON-LD. Since IPFS is a tree dag structure, the JSON-LD spec (or a simplified version of it) might fit IPFS really, really well. This would give IPFS all the power of the semantic web with very little overhead.

an ipfs object is a tree like json or anything else. this means that all the solutions available to JSON (inc JSON-LD, JSON-schema, and so on) are available to IPFS. moreover, it is trivial to represent RDF triples as ipfs objects. hence, you can do anything and everything.

real data is very messy. nobody in the world has succeed in forcing people to adopt a particular data typing system-- and i'm not going to sink time into those arguments. The only solution i think is viable in the long term is to make a system flexible enough for people to do whatever they want, and just rigid enough so everything interlinks.

now, the preferred way -- the way we'll suggest people do things -- is likely going to be the @context / @type from the (amazingly powerful and simple) JSON-LD.
