Types in MQL
Getting the types of a topic:
[{
"id": "/en/toronto",
"type": []
}]
types of a base:
[{
"id": "/people",
"/type/domain/types": []
}]
Creating types
You can create your own types within Freebase, either in your Default domain or in a Base. See Schema for information on how to work with types, properties, etc.
Types of types
Moving a type to a different base
The best way to do this is to raise a JIRA ticket for the request.
The process involves several steps:
- Add a key in the new domain for the type.
- Remove the key in the old domain (optional).
- Move any synthetic views.
- Change the base in the /type/type/domain property of the type.
- Change the base topic inclusion. i.e. if there is /base/foo/type that includes /base/foo/topic, and it is moved to base/bar/type, the included type should be switched to /base/bar/topic and all topics of that type should be detyped/retyped accordingly
- Change permissions on all types, properties, and type descriptions (e.g., the /common/topic/article attached to the type) to the permissions of the new base.
