If others are confused - I couldn’t find the schema.org <http://schema.org/> context on the web page (which is why I was looking for an alternative explanation), but found this explanation on the GH tracker : 
The context doc is available by content negotiation from http://schema.org/ <http://schema.org/> or directly via http://schema.org/docs/jsonldcontext.json <http://schema.org/docs/jsonldcontext.json>
