| ELNK | episodeLink | Expresses an association that links two instances of the same act over time, indicating that the instance are part of the same episode, e.g. linking two condition nodes for episode of illness; linking two encounters for episode of encounter. |
| REFR | refers to | A relationship in which the target act is referred to by the source act. This permits a simple reference relationship that distinguishes between the referent and the referee. |
| RPLC | replaces | A replacement source act replaces an existing target act. The state of the target act being replaced becomes obselete, but the act is typically still retained in the system for historical reference. The source and target must be of the same type. |
| SPRT | has support | Used to indicate that an existing service is suggesting evidence for a new observation. The assumption of support is attributed to the same actor who asserts the observation. Source must be an observation, target may be any service (e.g., to indicate a status post). |
| SUBJ | has subject | Relates an Act to its subject Act that the first Act is primarily concerned with. Examples 1. The first Act may be a ControlAct manipulating the subject Act 2. The first act is a region of interest (ROI) that defines a region within the subject Act. 3. The first act is a reporting or notification Act, that echos the subject Act for a specific new purpose. Constraints An Act may have multiple subject acts. Rationale The ActRelationshipType "has subject" is similar to the ParticipationType "subject", Acts that primarily operate on physical subjects use the Participation, those Acts that primarily operate on other Acts (other information) use the ActRelationship. |
| XCRPT | Excerpts | The source is an excerpt from the target. |
