- Query by category

{{#ask:
[[Category:Locations]]

|?Has coordinates
|format=table
}}

{{
#ask:
[[Has coordinates::+]]

 [[Has location type::Country]]
 | ? Has coordinates
 | format = map
}}

- Customisation of maps

Mediawiki extensions

Widgets

The Widgets extension allows the creation of raw HTML pages that can be embedded (similarly to templates) in normal wiki pages. You do this by creating pages in the Widget namespace. They avoid the security problems of raw HTML in editable wiki pages because the privilege to edit in the Widget namespace is managed. Many pre-written Widgets are available.

See Extension:Widgets

See Widget library

Of possible interest are:

1. Youtube widget, allowing YouTube video player to be added to wiki page
2. Twitter account feed widget
3. Survey monkey widget - Allows placing of Survey Monkey surveys on your web page
4. Maps widget - probably don't need if have Google Maps extension? Widget appears to allow placement of a Googlke Map in a page, specified by size, with markers and map control instructions
5. Google Books widget - allows viewing of Google books pages in wiki, woth scroller, magnifier and search bar; image can be sized
6. SlideShare widget - allows display of SlideShare slideshows in wiki page
7. Alexa traffic graph widget - allows additon of Alexa traffic graph to wiki page

These widgets seem very easy to install, for example, the SlideShare widget simply requires (a) installation of MediaWiki Widgets extension (b) copying of the full source code from the MediaWiki widgets page to your wiki
