It's probably common knowledge, but there's a few scripts here -
http://wiki.foaf-project.org/w/DanBri/WikipediaISBNs - for extracting
isbns from wikipedia dumps. It found about half a million last time I
tried.

Fwd: ISBNs, owl:sameAs, etc

[Daniel O'Connor]

Psst, Chris, Tobias - any chance of RDFBookMashup rendering 'owl:sameAs
urn:isbn:12434567' ?

I might see if I can glue freebase's 1.8 million or so ISBNs onto
rdfbookmashup.

 I don't suppose anyone wants to mint a whole bunch of URNs for ISBNs via a
quick acre application?

I'm upset that
http://sameas.org/html?uri=urn%3Aisbn%3A9780670063260%0D%0A&x=0&y=0

Doesn't give me

:( WOE.

Thanks for announcing this Joachim. It is great to see more linked
data as rdfa getting out on the web. I'm particularly excited because
of your use of the oai-ore vocabulary to make historic newspaper
archives available, since we are doing something similar at the
Library of Congress [1].

You must've done something right because I just wrote a little naive
crawler [2] in a matter of minutes to pull down what looks like all
the rdfa you've put out there so far. It seem to have collected about
11,427 triples [3]. My rdfsum unix command line hack [4] came up with
these rdf:type counts:

   1533 
526 
526 
336 
185 
  2 
  2 

Does that sound about right for this initial release?

I noticed that you have chosen to link to names in the German National
Authority file like:

   dct:subject
 .

I seem to remember hearing at SWIB09 [5] that the Deutsche National
Bibliothek was thinking about minting URIs for entries in the
authority file that follow Linked Data best practices (hash or 303,
etc). Were you planning on modifying these appropriately when those
URLs became available? Right now the d-nb URL returns 200 OK, and it
isn't a hash URI. Theoretically it would be pretty easy to layer in
some rdfa into the page at d-nb that describes:

  http://d-nb.info/gnd/118646419#person

But I realize this is somewhat out of your control. I guess it would
also be possible to create a partial PURL [6] for
http://d-nb.info/gnd/ that would redirect, since I think the new PURL
software supports 303.

I was also interested to see that you have published some SKOS
Extensions [7] that are used to type each ore:Aggregation as a
specialization of skos:Concept:


a ore:Aggregation,
 ;
skos:prefLabel "Abbe, Ernst; 1840-1905 (PM20 Personenarchiv)"@de,
"Abbe, Ernst; 1840-1905 (PM20 Persons Archives)"@en .

It looks like the rdf that comes back for your skos extensions
vocabulary (nice hack with the rdf validator btw) doesn't define
PmPersonFolder--but perhaps I missed it? I'm guessing from the
skos:prefLabel assertion that the PmPersonFolder is a specialization
of skos:Concept?

Would it be OK for me to experiment with pulling down the aggregated
resource bitstreams (jpg, etc) and storing them on disk? It would just
be a single threaded little script. Part of the rationale behind the
ore use at LC [1] is to foster LOCKSS [8] scenarios where digital
objects are easier to meaningfully harvest.

Anyhow, I have rattled on enough for now I suppose -- I mainly wanted
to say how exciting it was to see your announcement, being from the
digital library tribe in the linked data community :-)

Re: Generate RDFa with Epiphany

[Martin Hepp (UniBW)]

Hi Benjamin,
Nice - can you create GoodRelations (http://purl.org/goodrelations/) 
patterns in RDFa for existing shop pages, e.g. identify price and 
product information?
Just spotting the product name, description, EAN/UPC code, and price 
would already very valuable.


Best
Martin


PS: Did you see the Amazon sponger data, e.g. at

Hi everyone!

Let me introduce the RDFa annotator Epiphany:

It uses configurable domain-specific Linked Data to enrich web pages 
with RDFa annotation, automatically.
These annotations link text passages to instances inside the Linked 
Data model.
Hovering an annotation with your mouse opens a lighting box with 
additional information from the RDF graph behind the instance's HTTP URI.


Epiphany runs at: http://projects.dfki.uni-kl.de/epiphany/
On the top right you'll find an example.

Under http://projects.dfki.uni-kl.de/epiphany/form, you can write your 
own text and receive RDFa content.


Currently, the underlying Linked Data model is a subset of DBpedia 
covering German politics.
In later versions you will be able to upload or link your own Linked 
Data model to annotate web pages with your own domain specific RDFa.


Please don't hesitate in giving me your comments :). Twitter hashtag 
is #RDFEPIPHANY

Ben

ANN: 20th Century Press Archives as ORE / Linked Data application - Technical Preview

[Neubert Joachim]

The 20th Century Press Archives is a collection of more than six million 
newspaper clippings, dating from the 19th century to 2005. They were collected 
by subject and cover persons, companies and commodities as well general 
subjects and events.
 
As a unique collection and part of our cultural heritage, the archives (up to 
1945) have been digitalized by German National Library of Economics (ZBW) in a 
project funded by DFG (Deutsche Forschungsgemeinschaft). Now we aim to make it 
widely acessible for humans and machines. The technical preview at
 
  http://zbw.eu/beta/pm20
 
is built of nested OAI-ORE aggregations, published as (currently static) HTML 
pages with embedded RDFa. Since we want to use DFG-Viewer 
(http://dfg-viewer.de) for viewing the actual content, we transforms the 
aggregations to currently quite basic METS/MODS. Our further plans include a 
database-driven implementation, where we want to explore ORE as a means for 
describing search result sets as well. 
 
Please feel invited to take a look at it - we would highly appreciate any 
feedback about our approach.
 
Cheers, Joachim
