Yesterday I made my first screencast ever. [ Check it out! ] It explains how you can display a map using the Maps extension for MediaWiki, how you can customize it, and how to interact with it. I’ve linked it from the Maps extension documentation page. Depending on the feedback I’ll get, I might make similar ones explaining how to create maps with markers, how to aggregate coordinates onto a map with Semantic MediaWiki, and how to use the Semantic Forms hooks of Semantic Maps.
Note: the application I used to create this screencast with does not have build in spellings correction, so expect at least one mistake in every 20 words or so 🙂
