The two days seminar centered on the use the Amaya tool and the SweetWiki service organised on 8 and 9th October in Liège was a great success. It offered the opportunity to mediators and validators of PALETTE's CoPs, members of three CoPs, developers and pedagogical partners to concretely live the PALETTE participatory design approach in a faithful way to what was envisioned at PALETTE's kick off meeting, twenty months ago.
