The digital portal Europeana opens up its dataset of over 20 million cultural objects for free re-use. The massive dataset is the descriptive information about Europe’s digitised treasures. For the first time, the metadata is released under the Creative Commons CC0 Public Domain Dedication, meaning that anyone can use the data for any purpose – creative, educational, commercial – with no restrictions. This release, which is by far the largest one-time dedication of cultural data to the public domain using CC0 offers a new boost to the digital economy, providing electronic entrepreneurs with opportunities to create innovative apps and games for tablets and smartphones and to create new web services and portals.
