What's cooking on GRDDL?

Peter Royal got me interested in GRDDL recently. It looks like something we may want to use here at Radar Networks for scraping data from the Web and turning it into RDF triples. After doing a little digging around lately, I'm wondering if there is a list of sites that support GRDDL yet? Or any apps that use GRDDL yet?

Ok, the specs (here's a backgrounder I did, with links) and tool implementations, (e.g. Jena GRDDL Reader for Java) are already mature enough to use. So now it's over to sites/apps that use it.

In principle, any microformats-enhance d HTML could be readable with a GRDDL tool, but few sites bother using HTML's profile attribute, which is a shame because the publishers aren't making their data unambiguous. Also GRDDL expects valid XML source data, and not all microformatted docs are XHTML. But these issues can be worked around, with the help of things like HTML Tidy or Tag Soup.

But GRDDL isn't just for HTML. It can also be used with potentially any XML, and if the maintainers of the XML format's namespace document are willing to make minor additions, every document using that format can overnight become parsable as RDF without any effort on the part of individual document creators.

The GRDDL Working Group is in the process of compiling a library of standard transformations.

I've put together a tiny example in the NSFW Profile and am actively using it on my blog. It's little problem solving instances like this, built up over time, that will be a great use case for GRDDL, I think.

Nova's Trip to Edge of Space

  • Stepsedgestratosphere
    In 1999 I flew to the edge of space with the Russian air force, with Space Adventures. I made it to an altitude of just under 100,000 feet and flew at Mach 3 in a Mig-25 piloted by one of Russia's best test-pilots. These pics were taken by Space Adventures from similar flights to mine. I didn't take digital stills -- I got the whole flight on digital video, which was featured on the Discovery Channel.

Nova & Friends, Training For Space...

  • Img021
    In 1999 I was invited to Russia as a guest of the Russian Space Agency to participate in zero-gravity training on an Ilyushin-76 parabolic flight training aircraft. It was really fun!!!! Among other people on that adventure were Peter Diamandis (founder of the X-Prize and Zero-G Corporation), Bijal Trivedi (a good friend of mine, science journalist), and "Lord British" (creator of the Ultima games). Here are some pictures from that trip...

  • Marin Spivack
    Marin Spivack is my brother. He is the one of the only western 20th generation lineage holders of the original Chen Family Tai Chi tradition in China. He's been practicing Tai Chi for about 6 to 10 hours a day for the last 10 years and is now one of the best and most qualified Tai Chi teachers in America. He just returned from 3 years in China studying privately with a direct descendant of the original Chen family that created Tai Chi. The styles that he teaches are mainly secret and are not known or taught in the USA. One thing is for sure, this is not your grandmother's Tai Chi: This is serious combat Tai Chi -- the original, authentic Tai Chi, not the "new age" form that is taught in the USA -- it's intense, physically-demanding, fast, powerful and extremely deadly. If you are serious about Tai Chi and want to learn the authentic style and applications, the way it was meant to be, you should study with my brother. He's located in Boston these days but also travels when invited to teach master classes.
