Key issues of information system building

• Used to be
• Data communication
• Nowadays
• System integration
• User involvement
• Service and lifetime aspects

3
The classical web environment

• Used to develop to contain shared information
  architecture within some application domain
• The most notable the library information system
  and their organization is DC (Dublin Core)
• Nowadays it needs practical expandability to
  other application domains
• It is a reminder about complexity in developing
  widely shared vocabularies and their sharing

Different approaches for unified service based IS
development
5
MODE project

• MODE stands for Management of Distributed
  Expertise in International RD Collaboration.
• MODE addresses the implications of networked
  manufacturing, marketing and customer support in
  its business process and operation modes

6
The aim of MODE project

• Create a unified and wide action plan for
  technology oriented development projects within
  the Ostrobothnia region by establishing
  hierarchical models, through which different
  actors can find each other in the various
  collaboration networks.

BSN network

• BSN is a network of higher education
  institutions, regional development organisations
  and other organisations in the Baltic Sea Region
  (Denmark, Estonia, Finland, Germany, Latvia,
  Lithuania, Poland, Russia, Sweden).
• Its purpose is to develop the Baltic Sea Region
  in accordance with EU policy

BSOU project

• Baltic Sea Open University
• Creation of a virtual university
• The list of courses provided by education
  organizations (BSN partners)
• Provide joint degree for their students

Problems of establishing common terminology among
BSN network partners

• Heterogeneous of partners, which come to the BSN
  network
• Difference in structure of organization and
  education process
• Language
• Culture
