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

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.
