POI groups are groups of Points of Interests (POI), shown in both Map views and POI views. The groups initially are represented as single objects in the POI and Map view, hiding their related content. Once a group is selected, it is possible to browse the content.
Every POI group is identified by an unique ID. The POI group object itself can use its own ID, where all related POI group items must then use the same ID of the group object.
