Aim : running Timeline from live data, obtained via RDF/SPARQL
1. Locate/create some RDF (I started with the RSS feed from Planet RDF)
2. Load it into a triplestore (I used Jena)
3. Run a suitable SPARQL SELECT query to produce XML results containing the data of interest attachment:rss_2006-07-09.rq
4. Use XSLT to convert this into JSON suitable for Timeline attachment:sparql2timeline_2006-07-09.xsl
5. Link this into Timeline
Mostly works, see screenshot attachment:timeline.png, clicking on an item makes it pop up, clicking and dragging moves the whole timeline left-right

Update: David Huynh fixed the CSS links etc : attachment:timeline.html, attachment:planetrdf.js
MortenFrederiksen has created a live SPARQL timeline service!
