Metadata for collaborative learning: what to reuse?

Metadata developments are common in standardization activities, not only for learning technology, but all areas of electronic information representation. However, development itself is not the final goal from a practical point of view. Our research project is developing metadata to represent, record and reuse collaborative learning (CL) activity. There are many alternatives and combinations of representation frameworks for CL metadata. The selection of the framework depends on the aim and the goal of metadata development. If the goal is focused on representing pedagogical aspects of CL, one should choose a different description framework from those discussed in standardization activities.
