The projects aims to technically enable as many content providers as possible to integrate their content into Europeana. Since different providers make their data available in different formats, a tool has to be developed that converts metadata from a diverse range of source formats into the EDM (Europeana Data Model). During the project, this will exemplarily be done for the autograph database Kalliope (Staatsbibliothek zu Berlin), the German text archive Deutsches Textarchiv (Berlin-Brandenburgische Akademie der Wissenschaften), as well as content of the Austrian national library (Österreichische Nationalbibliothek) plus a number of other sources.Metadata providers are strongly encouraged to make their data available under CC0, as all other licenses hamper further use by Europeana and scholars.Finally, Europeana is going to provide the aggregated data in a form which allows Digital Humanities scholars to make best use of them. In addition, basic services / functionalities (modeled on the humanities' "scholarly primitives") will be provided by Europeana.In this perspective, the proposed project is in line with theme 2 of the call (Digital Content) and targets its objective 2.1 (Aggregating content in Europeana). The proposed Best Practice Network will respond to all three possible actions, namely:Aggregation of existing digital cultural heritage content (WP1)Alignment of metadata and mappings with the specifications of Europeana (WP2)Improvements in the interoperability of CMSs and the Europeana platform (WP 2 and 3)In tackling these three actions we will take particular care to target one specific user community of Europeana, namely reaserachers in the field of "Digital Humanities" and the way these will interact with Europeana through our WP3. Furthermore, the data migration and enrichment workflow proposed as part of WP2 will be modeled in such a way as to allow for its reuse in the migration of almost any generic and proprietary source to the EDM target
