  10. Required metadata Workshop on CERIF, CRIS and Institutional Repositories, May 10-11, 2010, Rome

  11. Repository: operating in a known context • Implicit Assumptions • 1. • Language is Italian • Dept names are known • Classification by agreed vocabulary • Policies are those established by the Univ. • 2. • Dspace doc model • DC metadata • OAI-PMH harvesting protocol • 3. • Connected to GARR - GEANT network Univ. of Pisa Repository DSpace technology SERRA Univ. Center Workshop on CERIF, CRIS and Institutional Repositories, May 10-11, 2010, Rome

  12. e-Infrastructure: operating in an open framework • Implicit assumptions • e.g. • Agreed metadata format • Agreed harvesting protocol • Different language • Different doc policies • Different org policies • Different actors roles • Different quality measures • …… Aggregator Workshop on CERIF, CRIS and Institutional Repositories, May 10-11, 2010, Rome

  13. e-Infrastructure: processing and generating new content Different information objects manipulation workflows Aggregator Workshop on CERIF, CRIS and Institutional Repositories, May 10-11, 2010, Rome
