Bottles and teargas in Piazza Navona

I’ve just posted 100 or so photos from the anti-Bush protest in Rome last night. Zac and I were on the way to a restaurant when we stumbled into the protest in Piazza Navona, just by the Senate where Bush apparently was in meetings. We wandered around the square taking photos of the protesters, then […]

As snow through which the foot breaks

köniuači Originally uploaded by danbri. In our daily lives we all respond urgently to dangers that are much less likely than climate change to affect the future of our children. … Feb. 2 will be remembered as the date when uncertainty was removed as to whether humans had anything to do with climate change on […]

FOAF questions

FOAF questions… Are there parts of the FOAF vocabulary we should declare ‘core’, and stable (or stabilise)? Would anyone be interested to help translate such a subset? initially the class/property labels and definitions, perhaps later, the accompanying per-term definitions? (a friend helped make a start on translating some terms into Persian, and there’s a neglected […]

In email hell

I’m tagging this ‘rdf’ so it finds it’s way to my various friends and collaborators in the RDF and SemWeb community via planetrdf.com. Just a brief tale of this week’s woe, and a note on how to contact me while I fix things up. Since leaving W3C at the end of last year, my email […]

Who, what, where, when?

A “Who? what? where? when?” of the Semantic Web is taking shape nicely. Danny Ayers shows some work with FOAF and the hCard microformat, picking up a theme first explored by Dan Connolly back in 2000: inter-conversion between RDF and HTML person descriptions. Danny generates hCards from SPARQL queries of FOAF, an approach which would […]

SPARQL for vocabulary management: theory vs practice

I’ve lately been thinking about whether the named graph support in SPARQL can help us evolve vocabularies and associated code (eg. generators and translators) in parallel, so that we know when the RDF generators are emitting markup that uses properties which aren’t yet documented in the ontology; or when the ontology contains terms that aren’t […]

FOAF vocabulary management details

I have an action from the Vocabulary Management task force of the W3C SW Best Practices Working Group to document the way the FOAF namespace currently works. Here goes. The FOAF RDF vocabulary is named by the URI http://xmlns.com/foaf/0.1/ and has information available at that URI in both machine-friendly and human-friendly form. When that URI […]

Open Source Flash Development and WorldKit

Handy article, “Towards Open Source Flash Development” by Carlos Rovira. Background to looking at this is some great news: Mikel Maron is open-sourcing the WorldKit system, a lightweight Flash/SWF-based Web mapping application. So I’m interested to find some open source tools that would allow me to rebuild it from source. I also wonder whether SVG […]
