Occurrence:  0 .. unbounded
Status:  O
Type: epcis:ObjectEventType
 
  
Definition: An ObjectEvent captures information about an event pertaining to one or more physical objects identified by EPCs. Most ObjectEvents are envisioned to represent actual observations of EPCs, but strictly speaking it can be used for any event a Capturing Application wants to assert about EPCs, including for example capturing the fact that an expected observation failed to occur.

While more than one EPC may appear in an ObjectEvent, no relationship or association between those EPCs is implied other than the coincidence of having experienced identical events in the real world.
 
Description: Retrospective semantics:
• An event described by bizStep (and any other fields) took place with respect to each EPC in epcList at eventTime at location readPoint.
• (If action is ADD) The EPCs in epcList were commissioned (issued for the first time).
• (If action is DELETE) The EPCs in epcList were decommissioned (retired from future use).
• (If action is ADD and a non-empty bizTransactionList is specified) An association exists between the business transactions enumerated in bizTransactionList and the EPCs in epcList.
• (If action is OBSERVE and a non-empty bizTransactionList is specified) This event took place within the context of the business transactions enumerated in bizTransactionList.
• (If action is DELETE and a non-empty bizTransactionList is specified) This event took place within the context of the business transactions enumerated in bizTransactionList.

Prospective semantics:
• (If action is ADD) The EPCs in epcList may appear in subsequent events.
• (If action is DELETE) The EPCs in epcList should not appear in subsequent events.
• (If disposition is specified) The business condition of the objects associated with the EPCs in epcList is as described by disposition.
• (If disposition is omitted) The business condition of the objects associated with the EPCs in epcList is unchanged.
• (If bizLocation is specified) The physical objects associated with the EPCs in epcList are at business location bizLocation.
• (If bizLocation is omitted) The business location of the physical objects associated with the EPCs in epcList is unknown.
• (If action is ADD and a non-empty bizTransactionList is specified) An association exists between the business transactions enumerated in bizTransactionList and the EPCs in epcList.
Example: In the case where action is ADD and a non-empty bizTransactionList is specified, the semantic effect is equivalent to having an ObjectEvent with no bizTransactionList together with a TransactionEvent having the bizTransactionList and all the same field values as the ObjectEvent. Note, however, that a ObjectEvent with a non-empty bizTransactionList does not cause a TransactionEvent to be returned from a query.
