Changes
POI groups are groups of [[:Category:POI|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 set to the POI_GROUP_ID property. 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.
