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 […]

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 […]

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, […]

Google Social Graph API, privacy and the public record

I’m digesting some of the reactions to Google’s recently announced Social Graph API. ReadWriteWeb ask whether this is a creeping privacy violation, and danah boyd has a thoughtful post raising concerns about whether the privileged tech elite have any right to experiment in this way with the online lives of those who are lack status, […]

Google boost Jabber + VOIP, Skype releases IM toolkit, Jabber for P2P SPARQL?

Interesting times for the personal Semantic Web: “Any client that supports Jabber/XMPP can connect to the Google Talk service” Google Talk and Open Communications. It does voice calls too, using “a custom XMPP-based signaling protocol and peer-to-peer communication mechanism. We will fully document this protocol. In the near future, we plan to support SIP signaling.” […]

geo/photo raw materials from a walk around Bristol

I’ve just been for a walk around town, taking a few photos on the way, with the camera’s clock sync’d to that of my new GPS. I’ve not yet figured out the best tool to use (other than write my own) for hooking up the photo and location metadata. It’s easy enough to get the […]
