Element epcis:AggregationEventType/action
 
 
Type: epcis:ActionType
 
  
Definition: The Action field of an AggregationEvent describes the event’s relationship to the lifecycle of the aggregation.
Description:  The Action type is an enumerated type having three possible values:

ADD The EPCs named in the child list have been aggregated to the
parent during this event. This includes situations where the
aggregation is created for the first time, as well as when new
children are added to an existing aggregate.

OBSERVE The event represents neither adding nor removing children from the
aggregation. The observation may be incomplete: there may be
children that are part of the aggregation but not observed during this
event and therefore not included in the childEPCs field of the
AggregationEvent; likewise, the parent identity may not be
observed or known during this event and therefore the parentID
field be omitted from the AggregationEvent.

DELETE The EPCs named in the child list have been disaggregated from the
parent during this event. This includes situations where a subset of
children are removed from the aggregation, as well as when the
entire aggregation is dismantled. The list of child EPCs may be
omitted from the AggregationEvent, which means that all
children have been disaggregated. (This permits dissaggregation
when the event capture software does not know the identities of all
the children.)
Example:  AggregationEvent is used to capture events related to physical aggregations of objects, such as cases aggregated to a pallet.

Throughout its life,the pallet load participates in many business process steps, each of which may generate an EPCIS event. The action field of each event says how the aggregation itself has changed during the event: have objects been added to the aggregation, have objects been removed from the aggregation, or has the aggregation simply been observed without change to its membership?
