The Conference of European National Librarians members will use open licensing for their data.
Here's an excerpt from the press release:
Meeting at the Royal Library of Denmark, the Conference of European National Librarians (CENL), has voted overwhelmingly to support the open licensing of their data. CENL represents Europe's national libraries, and is responsible for the massive collection of publications that represent the accumulated knowledge of Europe. . . .
It means that the datasets describing all the millions of books and texts ever published in Europe—the title, author, date, imprint, place of publication and so on, which exists in the vast library catalogues of Europe—will become increasingly accessible for anybody to re-use for whatever purpose they want.
It will mean that Wikipedia can use the metadata, linking it to all sorts of articles; it will mean that apps developers can embed it in new mobile tools for tourism or teaching. Crucially, for information scientists, it will mean that vast quantities of trustworthy data are available for Linked Open Data developments, creating relationships between elements of information that's never been possible before. . . .
The first outcome of the open licence agreement is that the metadata provided by national libraries to Europeana.eu, Europe's digital library, museum and archive, via the CENL service The European Library, will have a Creative Commons Universal Public Domain Dedication, or CC0 licence.
