comment: Optional[str] = None

created_by: Optional[str] = None

definition: Optional[str] = None

domain: Optional[Reference] = None

holds_over_chain: Optional[List[Reference]] = None

inverse: Optional[Reference] = None

is_metadata_tag: Optional[bool] = None: Whether this relationship is a metadata tag. Properties that are marked as metadata tags are used to record object metadata. Object metadata is additional information about an object that is useful to track, but does not impact the definition of the object or how it should be treated by a reasoner. Metadata tags might be used to record special term synonyms or structured notes about a term, for example.

range: Optional[Reference] = None
