Yahoo Local has announced that they’re now publishing their data in microformats. Included are hCards, hCalendars and hReviews.
I’m not sure how many instances of data this is, but its likely in the millions. Add that to hundreds of thousands of events on Upcoming.org, thousands of reviews on Yahoo! Tech and millions of hCards on Flickr profiles and Yahoo! is easily the largest support of microformats today.
If you’re coming to tomorrow night’s party and would like one of the ever-popular Microformats t-shirts, we’ll have a table setup to sell them (cheap, I promise!).
Of course, we know you can’t all make it to the party here in San Francisco (but you’d come if you were nearby, right?), so if you want to get your hands on a shirt, Chris Messina, who’s done tons of work as a Microformateer, has put the shirts up for sale.
Hot off the presses! Stay tuned to the party wiki page for more information on sponsors, giveaways, and, most importantly, fresh new code…
For many of you this is old news, but I just wanted to make sure everything’s seen it…
The week before last, we at Technorati launched an experimental Microformats Search tool in our “kitchen” (where you can taste the products before they’re fully “baked”).
This is an early stage release, but we wanted to get it out in the world for you to try.
In addition to the search tool, we’ve also started Pingerati.net, a ping system for microformated pages. We’re treating this as a community project, too, in which others can recieve the stream of pings for indexing. If you’d like to start recieving pings, just let us know!
Sean McGrath has written an entertaining, enlightening piece, musing about the economic arguments for microformats. Go read Master Foo’s Taxation Theory of Microformats, but first, a preview:
“History has shown that the only way to reduce information processing complexity to zero is for applications on the value chain to have build-it knowledge of the information formats they work with. XML, RDF, UML and so on are not formats so much as meta-formats. Consequently, built-in knowledge of any of these does not amount to zero complexity. XML is not a file format. It is a file format for file formats. This distinction is all important when calculating complexity.
