Remembering Aaron Swartz

“One of the things the Web teaches us is that everything is connected (hyperlinks) and we all should work together (standards). Too often school teaches us that everything is separate (many different ‘subjects’) and that we should all work alone.” —Aaron Swartz, April 2001. So Aaron is gone. We were friends a decade ago, and […]

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 […]

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 […]

NISO/CLIR/RLG – Technical Metadata Elements for Images Workshop (18-19th April 1999)

Visual SPARQL query tools

Quick links – thinking about tools that allow graphical SPARQL query authoring… OpenLink Virtuoso: InteractiveSparqlQueryBuilder (in HTML/CSS/.js). Pictured below; extensive documentation and screenshots linked from their main page. …an ancestor of which was Damian Steer’s RDFAuthor tool for MacOSX, which could generate Squish (a SPARQL precursor) and query services over the ‘array of hashtables’ SOAP-for-rdf-query […]
