Common Relationship Type

These relationship types can be made between any entities in the CTIM.

• duplicate-of - is a copy of some other object.
• related-to - a generic relation to another object. Please use one of the defined entity relationships below if at all applicable.
• derived-from - is based on another object, but is different. For example, if I am making a copy of an AttackPattern record that is located in the global CTIA instance, so that I can edit it locally in my organizations CTIA instance, than I would record a derived-from relationship in my local CTIA instance.
