What does that mean in practice?
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 potential to create new relationships between datasets from Europe’s greatest libraries creates what an expert in Semantic Web technology, Dr Stefan Gradmann, Professor of Library and Information Science at Humboldt University, Berlin, has called a ‘knowledge-generating engine’.
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. This metadata relates to millions of digitised texts and images coming into Europeana from initiatives that include Google’s mass digitisations of books in the national libraries of the Netherlands and Austria.
Bruno Racine, new Chair of CENL and President of the Bibliothèque nationale de France, and Dr. Elisabeth Niggemann, former Chair of CENL and Director of the Deutsche Nationalbibliothek, welcomed the leadership shown by CENL. Dr Niggemann said, ‘Providing data under an open licence is key to putting cultural institutions like our national libraries at the heart of innovations in digital applications. Only that way can society derive full social and economic benefit from the data that we’ve created to record Europe’s published output over the past 500 years. The best analogy is between bottled water and a water main. Rather than bottling it and branding it, we’re putting data on tap, so that everyone has free and open access, and can use it for whatever purpose they need.’
This resonates with the words of the European Commissioner for the Digital Agenda, Neelie Kroes, who in her speech to the Open Europe Summit this week said, ‘I am convinced that the potential to re-use public data is significantly untapped. Such data is a resource, a new and valuable raw material… To mine it would be an investment which would pay-off with benefits for all of us.’
As well as demonstrating strategic leadership in the heritage and information sectors, the pay-off for the libraries is twofold. Firstly, as their data becomes pervasive online, it will lead users back to its source, encouraging visits both both online and onsite. Secondly, their data will be enriched by contact with complementary data sources, and be available for them to re-use to upgrade their own services to users.
