Advanced AV Device Queries
This page showcases advanced queries powered by Semantic MediaWiki (SMW). Every AV device in the wiki stores its specs — brand, device type, format family, inputs, outputs, and more — as structured semantic properties. That means we can ask the wiki surprisingly specific questions and get live, always-up-to-date answers.
These queries run against real data in the wiki, so as new devices are added and existing ones are updated, the results here update automatically.
Want to learn more about writing your own queries? See the SMW inline queries documentation.
Running your own queries
You can play around with SMW queries using the built-in query interface at Special:Ask, or try copying the below example queries to your sandbox.
