Interface for PROV Start association.

PROV-DM Definition for Start: Start is when an activity is deemed to have been started by an entity, known as trigger. The activity did not exist before its start. Any usage, generation, or invalidation involving an activity follows the activity's start. A start may refer to a trigger entity that set off the activity, or to an activity, known as starter, that generated the trigger.

The constructor method ProvFactory.newWasStartedBy(QualifiedName, QualifiedName, QualifiedName, QualifiedName) can be used to create an instance of Start. The following code snippet creates a new start statement, with a role attribute, and current time. The instance of start is given an identifier myId. 

 QualifiedName myId= ... ;  // some qualified name
 QualifiedName activityId= ... ;  // some activity qualified name
 QualifiedName triggerId= ... ;    // some trigger qualified name
 WasStartedBy myWasStartedBy=provFactory.newWasStartedBy(myId,activityId,triggerId,null);
 myWasStartedBy.getRole().add(provFactory.newRole("trigger"));
 myWasStartedBy.setTime(provFactory.newTimeNow())
