Communities of Practice: The Role of Classification Schemes and Taxonomies - E-Learning Queen

Through Stephen Downes' OLDaily, I stumbled on to this: An interesting stroy of a teacher looking for learning materials to re-use:E-Learning Queen: Communities of Practice: The Role of Classification Schemes and Taxonomies Could be quite useful for the EUREA project, as a possible use-case or scenario.
The conclusion of the post seems to be that taxonomies and classification schemes (such as the ones that we are investigating in our LERU-projects, are indispensable. Stephen Downes disagrees with this conclusion though.
