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 […]

XMPP untethered – serverless messaging in the core?

In the XMPP session at last february’s FOSDEM I gave a brief demo of some NoTube work on how TV-style remote controls might look with XMPP providing their communication link. For the TV part, I showed Boxee, with a tiny Python script exposing some of its localhost HTTP API to the wider network via XMPP. […]

WordPress trust syndication revisited: F2F plugin

This is a followup to my Syndicating trust? Mediawiki, WordPress and OpenID post. I now have a simple implementation that exports data from WordPress: the F2F plugin. Also some experiments with consuming aggregates of this information from multiple sources. FOAF has always had a bias towards describing social things that are shown rather than merely […]

JQbus: social graph query with XMPP/SPARQL

Righto, it’s about time I wrote this one up. One of my last deeds at W3C before leaving at the end of 2005, was to begin the specification of an XMPP binding of the SPARQL querying protocol. For the acronym averse, a quick recap. XMPP is the name the IETF give to the Jabber messaging […]

RDF in Ruby revisited

If you’re interested in collaborating on Ruby tools for RDF, please join the public-rdf-ruby@w3.org mailing list at W3C. Just send a note to public-rdf-ruby-request@w3.org with a subject line of “subscribe”. Last weekend I had the fortune to run into Rich Kilmer at O’Reilly’s ‘Social graph Foo Camp‘ gathering. In addition to helping decorate my tent, […]

Ruby client for querying SPARQL REST services

I’ve started a Ruby conversion of Ivan Herman’s Python SPARQL client, itself inspired by Lee Feigenbaum’s Javascript library. These are tools which simply transmit a SPARQL query across the ‘net to a SPARQL-protocol database endpoint, and handle the unpacking of the results. These queries can result in yes/no responses, variable-to-value bindings (rather like in SQL), […]
