This paper presents the EuropeanaLocal project, funded by the European Commission that aims to assist cultural repositories to provide access to digital content that they hold to Europeana, the European Digital Library. The paper emphasizes at the effort of Greek Institutional Repositories to provide cultural content to Europeana via their involvement at the EuropeanaLocal project. Greek libraries, museums and archives content providers trying to adopt interoperability standards, the automated metadata harvesting model of Europeana, enrich their metadata by applying the European Semantic Elements metadata schemas in order to be able to migrate their metadata and make available their content of immense value to Europeana. Finally, the paper analyzes the results of a research conducted in Greek repositories participating in the project, which demonstrates their readiness for this project, problems encountered, the diversity of materials and standards that they are used, etc. Finally, the paper illustrates the growing opportunities arise for libraries and other cultural institutions (archives, museums) through their participation in the EuropeanLocal Project.
