Semantic Drilldown
I installed Semantic Drilldown which is written by Yaron Koren who is also the author of Semantic Forms. The extension is used for selecting articles by category and semantic property. It has a "filter" namespace which is used for creating articles which work like category pages but for more specific queries - exactly the kind of stuff we're needing :-) It also adds three special pages, Special:BrowseData for making selections, and Special:Filters and Special:CreateFilter for managing filter articles. He's developed these things from requests by clients he's set up SMW's for. See a brief history of his development path on his MediaWiki user page
This means that we won't need to develop anything for selections/queries/filters, ListView can be very simple and handle only the AJAX/API integration part and leave all the rest to the existing extensions.
