KEx objectives

• Supporting distributed and heterogeneous
  organizations in managing their knowledge
  processes, by technologically implementing the
  basic DKM concepts
• Autonomy ? by a set of document management
  functionalities
• Coordination ? by a set of knowledge exchange
  functionalities

System requirements
? Our choices

• We have implemented a P2P system where each peer
  must be able to
• Create and manage a knowledge representation
• Context Markup Language
• Context Editor
• Context extraction tools
• Declare its existence in the network
• Advertisement
• Discover other available / active peers on the
  network
• Discovery module
• Ping module
• Discover, create and join to federation of peers
• Advertisement
• Discovery module
• Membership module
• Ask and receive information from them
• Knowledge Exchange module
• Provide information to them
• Knowledge Exchange module
• Propagation module

Personal conclusions about the KEx experience

• WHAT IS GOOD
• The collaboration with business and external
  partners
• The local connection and interaction with the
  conceptual groups
• A working together team!
• WHAT COULD BE BETTER
• The bureaucratic and administrative stuff (time
  and energy spending!!!)
• New technological equipement?
