This Code system is used in the following value sets:

The type of trigger.

This code system defines the following codes:

1named-event Named EventThe trigger occurs in response to a specific named event, and no other information about the trigger is specified. Named events are completely pre-coordinated, and the formal semantics of the trigger are not provided.
1periodic PeriodicThe trigger occurs at a specific time or periodically as described by a timing or schedule. A periodic event cannot have any data elements, but may have a name assigned as a shorthand for the event.
1data-changed Data ChangedThe trigger occurs whenever data of a particular type is changed in any way, either added, modified, or removed.
2  data-added Data AddedThe trigger occurs whenever data of a particular type is added.
2  data-modified Data UpdatedThe trigger occurs whenever data of a particular type is modified.
2  data-removed Data RemovedThe trigger occurs whenever data of a particular type is removed.
1data-accessed Data AccessedThe trigger occurs whenever data of a particular type is accessed.
1data-access-ended Data Access EndedThe trigger occurs whenever access to data of a particular type is completed.

CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
