Example of how a simple OWL ontology / RDFS vocabulary could be defined with JSON-LD, defining the meaning of properties and classes. The second file shows the RDF triples of the vocabulary by using the JSON-LD sandbox. As a visualization - see http://www.essepuntato.it/lode/owlapi/https://gist.github.com/stain/7690362/raw/114f836a64291a3f894c44…
