Kartographer, a new extension to allow map inclusion directly into wiki markup, needs to support additional GeoJSON layers - both on the server (kartotherian) and on the client (leaflet). Also, it needs to support multiple indexable entries, like Points Of Interest (POIs), similar to how <cite> indexes things.
