  • Network architectures (OAI)Semantic information retrieval (Semantic Web)ethnoArc

  • From simple networks to the OAI

  • Interoperability "the ability of two or more systems or components to exchange information and to use the information that has been exchanged (Institute of Electrical and Electronics Engineers. IEEE Standard Computer Dictionary: A Compilation of IEEE Standard Computer Glossaries. New York, NY: 1990)

  • Interoperability?

  • different archive users have different requirementsre-use of existing infrastructures (e.g. GBV)to avoid maintenance of own webOPACnot very much work (reuse)
