I guess I already pushed out enough ARC spam today, so I'll keep things short: SPARQL is now a W3C Recommendation!

What I'm personally very happy about is the Implementation Survey which features two pure-PHP implementations*. This really opens the door for mainstream Web Developers to start exploring RDF and SPARQL on off-the-shelf hosted web servers. Everything I create these days (e.g. the ARC site, including the bots and archive generators there, or this blog) is powered by SPARQL. It's an amazing productivity booster as you never have to worry about complicated JOINs or evolving database schemas again. You can just code away and it's great fun to work with. Want more Testimonials? The Data Access Working Group collected quite a number of them from W3C member organizations.

* Don't let yourself be fooled by RAP's low report scores, their SPARQL engine is quite mature, they just didn't run the whole test suite.
