In case you missed it descriptive metadata from the National Library of France (BnF) became available as open data on January 1, 2014.
BnF has chosen to place its descriptive metadata (bibliographic and authority data) under the “open license” of the state, which allows free reuse with mandatory reference to the source. This choice was approved by a vote of its Board of Directors November 28, 2013.
As of 1 January 2014, all the data catalogs BnF (more than 12 million bibliographic records, 2.5 million validated authority records) will be available for free, for any kind of reuse, including commercial, with the obligation to quote the source.
Simplifying, facilitating and promoting the dissemination and exploitation of metadata to the BNF and by different operators and partners, this method allows the Library to participate fully in the cooperative movement and bibliographic sharing in the context of national and international projects .
At the national level, including legal interoperability will promote exchanges with library catalogs of Higher Education and Research, which adopted the same license for its own data.
The scope of cooperation also extends to all players in the book chain, with which it agrees to share the benefits arising from the investment of public power in cataloging and bibliographic indexing, for the benefit of the French edition.
Open data is intended to enhance the data libraries and facilitate their relationship with other communities present on the web. More broadly, it is to promote, via the web, the use of benchmarks and quality, while allowing the monitoring of their reuse.
