ANN: datos.bne.es, the new Linked Data service from the National Library of Spain

The *National Library of Spain* (BNE) (www.bne.es <http://www.bne.es>) 
and the *Ontology Engineering Group* (www.oeg-upm.net 
<http://www.oeg-upm.net>) are glad to announce the new *datos.bne.es 
<http://datos.bne.es> (http://datos.bne.es)* Linked Data service (in 
Spanish).

This new service represents a milestone of the Linked Data project 
started by the end of 2011 and that already published*Linked Open Data 
under a Public Domain license* (Creative Commons CC0). We have been 
working to improve many aspects of the service and would like to share 
with you some *key features*:

*A new way to search, discover and explore*
*-------------------------------------------------------------*

The new (beta) portal exploits linked data *to create better experiences 
for the user*. A graph with millions of new connections allows the user 
to explore the collections comprehensively and across three core 
entities: authors, works and topics. The search engine (e.g., 
http://datos.bne.es/find?s=joyce <http://datos.bne.es/find?s=joyce>) 
also uses this graph to retrieve and rank entities, presenting relevant 
information to the user and allowing for simple, easy-to-use faceting.

Besides, we continue to offer a public SPARQL endpoint 
(http://datos.bne.es/sparql) for people to query and use the data for 
their own applications, content negotiation, and we also provide 
schema.org <http://schema.org> descriptions of authors and works using 
JSON-LD.

*More data, more links*
*-------------------------------*

We have published the full catalogue comprising *more than 9 million 
records and around 150.000 digitalized materials* that generate more 
than 140 million RDF triples. These linked data resources describe and 
give access to authors, organizations, topics, modern and ancient books, 
photographs, cartographic materials, drawings, manuscripts, or printed 
and manuscript music.

We provide around *1.4 million sameAs links* and add links to new 
datasets such as ISNI, data.bnf.fr <http://data.bnf.fr>, id.loc.gov 
<http://id.loc.gov>, and geo.linkeddata.es <http://geo.linkeddata.es>. 
More importantly, we have significantly increased the internal links 
between authors, bibliographic resources and digital materials.

*The BNE data model*
*-----------------------------*

The BNE vocabulary, inspired by the FRBR data model, reuses and 
integrates several vocabularies such as IFLA FRBR, ISBD, or RDA, among 
others. The vocabulary is available for both humans and machines at 
http://datos.bne.es/def/, it is documented in English and Spanish. We 
will soon provide alignments to the aforementioned vocabularies.

*Help us to improve*
*---------------------------*

We would very much appreciate receiving feedback from the community. If 
you have any ideas/comments on how to improve the service, you encounter 
issues/problems, you want to collaborate, etc. please get in touch. But 
first of all, we invite you to visit:

Thanks and our best wishes.

Manchado, on behalf of the OEG and BNE teams.
