I am in Ohrid in Macedonia for the European Summer School on Technology Enhanced Learning & Knowledge Management 2008. As ever it is a pleasure to meet colleagues from all over Europe, and particularly from Eastern Europe. And the school is alo interesting in that it brings together researchers from a series of large scale European funded research projects. What are the themes of the school. It is a bit difficult to say at the moment.

One issue that a number of projects seem to be wrestling with is how to represent knowledge. There is the by now familiar debate about taxonomies, ontologies and tagging. I have a concern as to how much useful software is being created. To soem extent this is a tension within research projects which are both attempting to undertake fundamental research and at the same time involve users.

Anyway, as in Salzburg Cristina and I have created a tweme (a mash up of twitter, delicious and flickr) for the summer school. You can follow our tweme here. Feel free to participate. The tag is #scohrid.
