data.australia.gov.au and rdfa

Friday, January 29, 2010

In my previous blog post I was trying to demonstrate the virtues of data.gov.uk making the descriptions of their datasets available as RDFa. Just this morning I learned from Mark Birbeck that the folks down under at data.australia.gov.au did this last October!
For example this page describing a dataset for public Internet locations has this RDF [...]

data.gov.uk and rdfa

Tuesday, January 26, 2010

The recent public release of the UK Government’s data.gov.uk site got picked up by the press last week in articles at The Guardian, Prospect Magazine and elswhere. 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) [...]

Hacking O’Reilly RDFa

Tuesday, December 22, 2009

I recently learned from Ivan Herman’s blog that O’Reilly has begun publishing RDFa in their online catalog of books. So if you go and install the RDFa Highlight bookmarklet and then visit a page like this and click on the bookmarklet you’ll see something like:

Pooh began to feel a little more comfortable, because when you are a Bear of Very Little Brain, and you Think of Things, you find sometimes that a Thing which seemed very Thingish inside you is quite different when it gets out into the open and has other people looking at it.

The Complete Tales of [...]

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 [...]

w3c semweb use cases and lcsh

Friday, September 5, 2008

Via Ivan Herman I learned that the Semantic Web Use Cases use concepts from lcsh.info. For example look at the RDFa in this case study for the Digital Music Archive for the Norwegian National Broadcaster. You can also look at the Document metadata in a linked data browser like OpenLink. Click on the “Document” and [...]

oai-ore and the shadow web

Friday, February 22, 2008

The OAI-ORE meeting is coming up, and in general I’ve been really impressed with the alpha specs that have come out. It’s not clear that there’s an established vocabulary for talking about aggregated resources on the web, so the Data Model and Vocabulary documents were of particular interest to me.
One thing I didn’t quite understand, [...]
