AMADIS is an virtual environment that provides support for "Learning Projects" pedagogy. It's pourpose is to re-think the traditional way that schools work. In AMADIS the child acts like an scientist, researching topics of their own reality.
This is a way of creating virtual libraries. I catalogue the books (or DVDs etc.) that I have. My friends do the same. As well as allowing me to organise myself easily is also means that if I'm after a book I can easily find which of my friends has it.
