DPL is a flexible report generator for MediaWiki.
You can use it to generate dynamic lists based off content in the wiki.
The simplest example would be making a list of all pages that belong to the location category AND also a specific setting category. This way you can have a list of only Aglon locations for example.
See https://www.mediawiki.org/wiki/Extension:DynamicPageList3 for further documentation and more advanced usage.
