Before the summer the Swedish national librarian, Gunnar Sahlin, signed an agreement effectively releasing the Swedish National Bibliography and authority files into the public domain. We are now pleased to announce the general availability of these records (see below for details). We see the investment in Open Data as a strategic one and one that is needed to ensure long term sustainability and competition when it comes to the services needed by libraries and their users as well as the right to control over their collections. The license chosen is CC0 which waives any rights the National Library have over the National Bibliography and the authority data.
There are two ways to access the data, as Atom feeds with references to the records and using (a somewhat rudimentary implementation of) the OAI-PMH protocol. See the table below.
|National Bibliography||feed, OAI-PMH|
|Authority Data||feed, OAI-PMH|
|Authority Data (persons)||feed|
|Authority Data (subjects)||feed|
|Authority Data (organisations)||feed|
The National Bibliography and authority data is part of Libris, the Swedish Union Catalogue, and the long term goal is to release the whole database under an open license, though this will undoubtedly take some time. The data contains links to Wikipedia, DBPedia, LC Authorities (names and subjects) and VIAF. VIAF has also been used to find some of these links. These channels are provided as a complement to the Linked Data implementation.
