Where can I find RDF examples & the ontology definition?

[flyon]

Im interested in AD4M and I'm trying to understand it better. The readme mentions it's essentially an ontology. And you describe in the AD4M readme that implementing AD4M in your app would consist of

creating RDF/semantic web style triplets that associate expressions in order to represent app specific semantics

Hence I was first of all expecting to find an AD4M ontology file in JSON-LD or turtle. And an example implementation using RDF. If such an ontology or example implementation with RDF exists, could you point me to them? Perhaps with a hyperplink in the readme.
