1. INFORMATION ARCHITECTURES FORSEMANTIC WEB APPLICATIONS Kimmo Salmenjoki, Yaroslav Tsaruk Univestity of Vaasa Gurusamy Arumugam Madurai Kamaraj University University of Vaasa, Department of Computer Science, Finland

2. Key issues of information system building • Used to be • Data communication • Nowadays • System integration • User involvement • Service and lifetime aspects University of Vaasa, Department of Computer Science, Finland

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 University of Vaasa, Department of Computer Science, Finland

4. Different approaches for unified service based IS development University of Vaasa, Department of Computer Science, Finland

5. MODE project • MODE stands for “Management of Distributed Expertise in International R&D Collaboration”. • MODE addresses the implications of networked manufacturing, marketing and customer support in its business process and operation modes University of Vaasa, Department of Computer Science, Finland

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. University of Vaasa, Department of Computer Science, Finland

7. 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 University of Vaasa, Department of Computer Science, Finland

8. 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 University of Vaasa, Department of Computer Science, Finland
