[open-bibliography] British Library data announcement

[Deliot, Corine]

William, many thanks for your feedback. 

Re: isbns.
They appear in dcterms:identifier [http://purl.org/dc/terms/identifier] and the range of that property is rdfs:literal [1], which is why we have recorded them as a string literal.

The latest version of the data available from us (version 0.3.1) also includes isbns and issns in bibo:isbn and bibo:issn. These are sub-properties of bibo:identifier, which has the range of rdfs:literal [2], which is why we again have recorded these as string literals.

My understanding is that if we wanted to treat isbns and issns as resources, then we would have to use dc:identifier http://purl.org/dc/elements/1.1/identifier, which had no range defined or another property from another RDF vocabulary with the appropriate range.

I will lowercase the urn:isbn, urn:issn in our next release, thanks.

We are aware that blank nodes are an issue but we are not in a position to mint our own URIs yet. We are investigating how best to do this.

Thanks again

Best, Corine

one that stands out, while not an error in rdf syntax is the treatment
of isbns. they appear as dc:identifier, which is fine, though
bibo:isbn might be better, but they are expressed as
URN:ISBN:0123456789 - as a string literal rather than a
resource. additionally it is uncommon th uppercase the prefix there,
and case does matter.

also, none of the records have uris. they are all identified with
blank nodes. so one of the first things we did was to mint uris for
them - htttp://bnb.bibliographica.org/entry/... (sorry, on the train
right now, typing into my mobile so i can't get a real example, but if
you run the default sparql query you should find something). in an
ideal world each record in the british national bibliography will have
an identifier like http://bnb.bl.uk/GB123ABC that will dereference,
etc. - note for this dataset we've used the bnb id - which itself
wants a special predicate rather than just dc:identifier, or maybe a
datatype for use with skos:notation - as the primary identifier, since
that seemed appropriate...
 
last note, http://bnb.bibliographica.org/ is not yet for general
consumption, still need to hook together some bits of the user
interface for searching etc. over the next couple of days, so if you
do poke around, please consider it a preview for an interested
community rather than a finished product.

cheers,
