The time has come for the semantic web to SPARQL

PodTech recently published three videos of Sir Tim Berners-Lee in action. The first was a presentation of the semantic web at HP Labs in Palo Alto, California, the second was the resulting Q&A session, and the third a brief interview with Robert Scoble. The ever watchful Paul Miller of Talis has linked to all three (tinyurl.com/

The semantic web has been much heralded. A headline back in 2002 announced: "The semantic web lifts off". One of that article's authors was Berners-Lee. Yet six years later it is hard to use the term "lift-off" even though a lot of the architectural underpinnings are already in place. Some tough problems lie ahead. Trust, in particular.

It reminds me of the many IT projects that progress rapidly to 80% and then slow to a crawl. However, Berners-Lee expects the new year to start with a very useful new tool called SPARQL (yep, it's pronounced "sparkle"). Like GNU before it, it is a recursive acronym (it stands for SPARQL Protocol And RDF Query Language) and is designed to pick up truly relevant information from the internet in RDF (Resource Definition Framework) format.

Until now, web searches have parsed the content of web pages and assembled the results as lists of apparently matching URLs. But this is a fairly hopeless process when it comes to machine-processing the results.
