I've been looking at assorted ways how to (a) replace my German Folklore Map with something #OpenStreetMap -based (b) making it filterable based on narrative elements (such as "dragon", "treasure", and so forth), and (c) integrating it into my new #Mediawiki wiki.
Based on my investigations so far, I think my best bet is to put all the map information into a #GeoJSON files, and add the element I want to filter by as Properties of the elements.
The trick seems to be which Mediawiki extensions - Map, Kartogtapher and so forth - allow me to filter these Properties so that I can create a custom map that (for example) only displays all markers tagged with "dragon" without having to create a custom GeoJSON file for each variant map.
Can anyone help me out?
