Hi,
When I try to dereference a work:
http://datos.bne.es/edicion/Mimo0000379726
it does the correct 303 redirects based on content type, but I get an
empty result for both Turtle and RDF/XML.
For authors:
http://datos.bne.es/autor/XX1000054
there is some data, but it contains no links to the author's works, so
it isn't very "Linked Data".
There is problably some mismatch between the data feeding the content
negotiation and the data feeding the portal due to the recent updates we
made, we will look more in detail into this. It is not an issue of not
being linked data, if we have links presents will give them back to you
in both views HTML and RDF flavours as in:
http://datos.bne.es/autor/XX1020842.ttl and
http://datos.bne.es/autor/XX1020842.html
Also, there seems to be some confusion in the URL pattern: the subject
URL within the RDF is http://datos.bne.es/resource/XX1000054, i.e.
"resource" replaces "autor".
We have kept the canonical URIs for things that we published in previous
versions: http://datos.bne.es/resource/ which correspond to
non-information resources and use the 303 mechanism to provide different
representations, in this case changing to a typed URI pattern + the file
extension, this was motivated to support nicer URIs for the
human-oriented content of the portal and its similar to patterns like
the one used in DBpedia where they do /resource/ --> /page/ or
/resource/ --> /data/ + the file extension for RDF representations.
Thank you very much for your comments, they help us to improve the service.

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:
http://datos.bne.es
Thanks and our best wishes.
Daniel Vila Suero, Asunción Gómez Pérez, Ricardo Santos and Ana
Manchado, on behalf of the OEG and BNE teams.
