Semantic MediaWiki

Semantic MediaWiki (SMW) is a popular extension to MediaWiki that lets you store and query data in your wiki.

Maps integrates with SMW by adding support for geographical values. These values can then be queried together with other information stored in your wiki. Query results can be shown on maps, which can be customized the same way you customize standard maps provided by the Maps extension.

I created Maps and this documentation in my free time. If you are finding either useful, please consider supporting me.
