2. 1 Network architectures (OAI) 2 Semantic information retrieval (Semantic Web) 3 ethnoArc

3. From simple networks to the OAI

4. 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)

5. Interoperability? Archive User exchange

6. TYPE 1 (typical early library network) data repository single metadata structure several clients for data input several clients for data output

7. TYPE 2 (“meta network structure”) common metadata structure S3 clients for data input local data repository local data repository clients for data input local metadata structure S1 local metadata structure S2 common data repository clients for data output Variation with distributed searches
