  • **What is the Open-Knowledge System?Current limitations leading to a validation of our system.What are our goals of the Open-Knowledge System?Large scale in humans and machinesDiffentiation between types of participants, like average user, programmers Low integration effort with existing workOpen participationRe-use, re-use and re-useMeans to evaluate who is good and whos notWhy the Open-Knowledge system is a good idea?Comparison with MAS, P2P, Grids, WWW, SW How would the system look like?User perspective (screenshots and functionality)System overview in a technical sense (covered by D2.1b)
