- iterateOver
The iterateOver field specifies the order in which the Structured Analysis Harvester multiplies each field in order to create the right number and type of events. Each of the entity fields to use are separated by the '/' character and specifies the entity type used to populate the matching field in the event object.

Association fields generated from the entity loop are placed in "_iterator". For example, for "iterateOver": "entity1/entity2/geo_index", an _iterator object with the following fields is available in the Javascript: "_iterator.entity1_index", "_iterator.entity2_index", "_iterator.geo_index". These fields can be usefully used together with "creationCriteriaScript" scriptlets to filter out unwanted associations, eg when looping over entity1 and entity2 with the same entity type, the following script would ensure the association didn't involve the same entity: "creationCriteriaScript": "$SCRIPT( return _iterator.entity1_index != _iterator.entity1_index; )" |
In the example source below there are four entities that are being shown: one location entity, two victim entities, and one perpetrator entity. These visible entities are the entities referenced in the example specification above.
