Associations modify requests to return more information. Usually this requires extra calls to the AF or PI Data Archive servers so it is omitted by default. The action documentation indicates what associations it supports. The following associations are accepted:
-
Annotations Specifies to return the annotations associated with the AF value returned from a data request.
-
Paths Specifies to return all the full paths associated with the AF element(s) returned from a request.
