A collection of models.

When creating an object instance from a JSON representation, the fromJSON() method expects the presence of the correct $context value. When serializing and unserializing using these models, this is done automatically.
This makes it impossible to use the data for one entity as another.
The $contextVersion was added to enable clients that cache entities, e.g. in localStorage, to check if their application code is compatibel with the cached data.
