Please choose a more concrete title for your workshops. Chances that somebody clicks on a link "SMW" are much lower than on links "Semantic MediaWiki". That's why I don't use FEASW as a title for my soldering workshop ;-)
Well I'm somehow interested in it but less than for the OpenDuino stuff.
Depending on how you present the stuff I might feel bored very soon. What is that workshop exactly about? Is it like "I show you how you use this and that" or more like "This is how this functionality is implemented". It must be the first case if your title is not wrong.
