Busy sysadmin week. The main FOAF site is back, now hosted on Amazon EC2. Thanks to Stephane Corlosquet for all the time he spent fixing up the Drupal installation, after the recent server compromise. I’ve also moved over danbri.org (well, DNS is propagating), and migrated my blog into a completely fresh Wordpress installation. The FOAF namespace [...]

On the internet, no-one knows.
“Because most of the targeted employees were male between the ages of 20 and 40 we decided that it would be best to become a very attractive 28 year old female. We found a fitting photograph by searching google images and used that photograph for our fake Facebook profile. We also populated the profile with [...]
Skosdex progress: basic lucene search
I now have a crude Lucene index derrived from SKOS data. It is more or less a toy example, but somehow promising also.
Example below is a test against FAO’s AGROVOC. Each concept becomes a “document”, with a “word” field containing the prefLabel, and a “uri” field for the concept URI. I don’t index anything else [...]

Facebook problem statement
People want full ownership and control of their information so they can turn off access to it at any time. At the same time, people also want to be able to bring the information others have shared with them—like email addresses, phone numbers, photos and so on—to other services and grant those services access to [...]

Skosdex: SKOS utilities via jruby
I just announced this on the public-esw-thes and public-rdf-ruby lists. I started to make a Ruby API for SKOS.
Example code snippet from the readme.txt (see that link for the corresponding output):
require “src/jena_skos”
s1 = SKOS.new(“http://norman.walsh.name/knows/taxonomy”)
s1.read(“http://www.wasab.dk/morten/blog/archives/author/mortenf/skos.rdf” )
s1.read(“file:samples/archives.rdf”)
s1.concepts.each_pair do |url,c|
puts “SKOS: #{url} label: #{c.prefLabel}”
end
c1 = s1.concepts["http://www.ukat.org.uk/thesaurus/concept/1366"] # Agronomy
puts “test concept is “+ c1 + ” ” [...]

Family trees, Gedcom::FOAF in CPAN, and provenance
Every wondered who the mother(s) of Adam and Eve’s grand-children were? Me too. But don’t expect SPARQL or the Semantic Web to answer that one! Meanwhile, …
You might nevetheless care to try the Gedcom::FOAF CPAN module from Brian Cassidy. It can read Gedcom, a popular ‘family history’ file format, and turn it into RDF (using [...]

Cross-browsing and RDF
Cross-browsing and RDF
While cross-searching has been described and demonstrated through this paper and associated work, the problem of cross-browsing a selection of subject gateways has not been addressed. Many gateway users prefer to browse, rather than search. Though browsing usually takes longer than searching, it can be more thorough, as it is not dependent on [...]
