Today new apmodel features:
- User can add and override (required inheritance the class) own model to loader (core models is can't override, show warning)
- apmodel supports to preload json-ld schema from local (example, schema.org, activitystreams 2.0)
- The definition of
typeURI now uses a ClassVar called AS_URI. This reduces the effort required to automatically register models with load and eliminates the need to redefinetypefor each model.
