To create custom metadata relationships:	Customize Application

From the detail page of your custom metadata type, click New under Custom Fields.
For the field type, select Metadata Relationship.
Select either:
- Another custom metadata type that you want to be the child of the active custom metadata type.
- Entity Definition (Represents the metadata of a standard or custom object)
Public custom metadata types can’t be related to protected custom metadata types.
Create a record for storing the metadata relationship.
- If the Required box is checked, you can’t create a record for the parent types unless the child type has at least one record. A link to the records of the child custom metadata types is available from the parent custom metadata types record.
- For entity definitions, select the standard or custom object that represents the entity definition.

You can now query your custom metadata type or entity definition using Apex.
