The National Technical University of Athens’ School of Computer and Electrical Engineering has been the host of the IVML – Image, Video and Intelligent Multimedia Systems Lab – since 1988. Up till now, IVMLhas been involved in more than a 100 R&D projects, half of which have been funded by the European Commission. IVML has been a key technological member in Digital Libraries and particularly in the Europeana environment. The MINT-tool, developed by the lab, allows for the ingestion of metadata from multiple sources, the mapping of imported catalogue records to an intermediate schema and the transformation and storage of metadata in a repository. MINT has been successfully used in many Europeana-projects dealing with aggregation, content analysis and interoperability issues.
