Just watched some videos (after work ;)) of Burda`s Digital Lifestyle Day 05, which seems to be have been pretty posh an event (and quite a party).
Among quite a number of more or less important people from more or less important companies (folks from blogger.com, flickr, Google, Yahoo, Microsoft.. kind of everybody) Loïc Le Meur and Stefan Heidenreich had short presentations there, you find all the videos online.
I haven`t heard any of the speakers mentioning RDF so far, but some of them (Herr Heidenreich for example, explicitly emphasizing formats) should have (says the geek in me).

Well, although this sounds very much like an occasion for Marc to show up, Mr.Digital-Lifestyle himself is missing.

What you see above are some screenshots from two projects realized using mediagonal's IMS QTI v2.0 quiz engine we built last year.

The IMS Question and Test Interoperability v2.0 spec came out about a week ago, it`s meant to provide a standard for interactive assessments usable in whatever your learning management system might be, it deals with quite a number of question types, feedback and statistics, and includes a type system as well as a profile of XHTML.

Our quiz engine, written in Macromedia Flash, consumes such QTI XML files, along with further XML documents specifying some more special behavioral aspects and the entire layout specification. It should be able to plug into any system, for Moodle there is a special adapter component. Moodle is also the base for the projects shown above (for Paul Klee Zentrum and Jugend und Wirtschaft / LerNetz), we therefore improved Moodle`s question management and editing and implemented QTI v2.0 export.
In fact, I shouldn`t say "we" in this case: I did not write a single line of code for that software - nice to see a team growing and growing more powerful like that.

There's an interview with Stefano Mazzocchi in today's Berner Zeitung. In German, well done by This.
And sorry Stefano for sending journalists to you ;-)
