I am attempting to create a JSON-LD context which can be used in a closed / intranet environment with no access to the internet.
To this end I am trying to create my own context as there may be licensing issues copying schema.org wholesale and redistributing it.
I've seen that creating your own context is possible but I can't see anywhere that explains what the definition of that context should be. Can someone explain what it should be or point me at a description of an existing context as a starting point?
