a middle way for linked data at the bbc

Tuesday, March 2, 2010

I got the chance to attend the 2nd London Linked Data Meetup that was co-located with dev8d last week, which turned out to be a whole lot of fun. I figured if I waited long enough other people would save me from having to write a good summary/discussion of the event…and they have: thanks [...]

These have been supplemented by some more technical discussions at ReadWriteWeb, Open Knowledge Foundation, Talis, Jeni Tennison’s blog, and some helpful emails from Leigh Dodds (Talis) [...]

VocabularySoup (1)

Thursday, March 26, 2009

It’s been great to see RDFa being picked up by web2.0 publishers like Digg and MySpace. You can use the RDFa Distiller to extract the RDFa from a given web page u by constructing a URI like:

http://www.w3.org/2007/08/pyRdfa/extract?format=turtle&uri=u

Which translates kind of nicely into a command line utility to add to your ~/bin:

#!/bin/sh
curl “http://www.w3.org/2007/08/pyRdfa/extract?format=turtle&uri=$1″

So with that [...]

100,000 Books and FRBR

Monday, January 5, 2009

The news about 100,000 books on Freebase got me poking around with curl. I was pleased to see that Freebase actually distinguishes between a book as a work, and a particular edition of that book. To FRBR aficionados this will be familiar as the difference between a Work and a Manifestation:
For example here is a [...]

freebase and linked-data

Wednesday, October 29, 2008

Ok, this is pretty big news for linked data folks, and for semweb-heads in general. Freebase is now a linked-data target. This is important news because Freebase is an active community of content creators, creating rich data-centric descriptions with a wiki style interface, fancy data loaders, and useful machine APIs.
The web2.0-meets-semweb space is also [...]

SemanticProxy

Monday, October 27, 2008

I spent a 1/2 an hour goofing around with with the new (to me) SemanticProxy service from Calais. You give the service a URL along with your API key, and it’ll go pull down the content and then give you back some HTML or RDF/XML. The call is pretty simple, it’s just a GET:

GET [...]

terminology services sneak peak

Thursday, September 11, 2008

I just saw Diane Vizine-Goetz demo OCLC’s Terminology Services at the CENDI/SKOS meeting and was excited to see various things out on the public web. For example, the LCSH concept “World Wide Web” is over here:

http://tspilot.oclc.org/lcsh/sh2008114004

At the moment it’s not the most friendly human readable display, but that’s just a XSLT stylesheet away [...]

Martin Malmsten and linked library data

Tuesday, September 2, 2008

I’m currently listening to Richard Wallis’ interview w/ Martin Malmsten of the Royal Library of Sweden. It’s a really fascinating view inside a library, and the mind of a developer that are publishing bibliographic resources as linked data.
Partly as a dare from Roy Tennant to do something useful with linked-data, I spent 30 minutes w/ [...]

lingvoj

Wednesday, August 13, 2008

I’m just now running across lingvoj.org, a linked-data application for languages created by Bernard Vatant. lingvoj basically mints URIs for languages (using the ISO-639-1 code) and when resolved (yay HTTP) nice human and machine readable descriptions about the language are returned. So for example the URI for Chinese is:

http://www.lingvoj.org/lang/zh

If you click on that link, your [...]
