3.5 Common Relationships
Each SDO has its own set of relationship types that are specified in the definition of that SDO. The following common relationship types are defined for all SDOs. See section 1.4.3 for more information about relationships.
| Relationship Type | Source | Target | Description |
|---|---|---|---|
| derived-from | <STIX Domain Object> | <STIX Domain Object of same type> | The information in the target object is based on information from the source object. |
| duplicate-of | <STIX Domain Object> | <STIX Domain Object of same type> | The referenced source and target objects are semantically duplicates of each other. |
| related-to | <STIX Domain Object> | <STIX Domain Object of any type> | Asserts a non-specific relationship between two SDOs. This relationship can be used when none of the other predefined relationships are appropriate. |
