Digitisation is a topic that has attracted more and more attention even in the cultural world, leading to the development of specific digital solutions such as DSpace, LIDO and EDM. DSpace is a digital archiving service developed by Hawlett-Packard and MIT, being used by more than 2,000 organisations and institutions worldwide, and LIDO has over time become an industry standard developed to facilitate data harvesting and data interchanging. On the other hand, the EDM knowledge model, which is used for data ingestion in Europeana, has gained publicity precisely because of the increasing visibility of this data aggregator, which currently offers a collection of more than 50 million objects. Unfortunately, Europeana only allows ingestion of semantic structures built around the object-centric approach, thus diminishing the richness of the events. eCHO framework has been developed to facilitate the migration of DSpace archives and LIDO metadata to EDM-compliant datasets without losing the richness of the original data, while maintaining compatibility with Europeana. eCHO also integrates a temporal expression standardization solution and the Cultural Leaf Portal has been developed for data exploration. The validation of the framework was done on the Romanian cultural heritage metadata and on the sample provided by BCU Cluj.
