While everyone, well almost everyone, was fast asleep in London, Twitter quietly dropped a bomb-shell into their API announcements mailing list. Their new Trends API will help the service’s users answer the perennial question “what’s going on where am I“.

“(WOEIDs and GeoPlanet) gives us the opportunity to use colloquial geography rather than bounding boxes and radial searches and the like. I banged on about this in my talk at the AGI conference recently. I am such a geography bore. Anyway, we couldn’t have built Noticings without it.”
For those who like the technical gory details, Tom’s put up an excellent blog post to explain it all.
But it doesn’t stop at photos and Flickr, once you have a WOEID you can pass it to any of the ever growing number of web APIs that know how to handle WOEIDs, Yahoo’s GeoPlanet, Placemaker, Fire Eagle, YQL as well as services that speak long/lat. That’s a lot of services, and the number’s growing. Plus you get access to the horizontal and vertical relationships, parents, children and neighbours that a WOEID has as well as more obtuse colloquial geographies, all in multiple languages.
All of which is somewhat apt as I’m writing this in Munich at the back of the Telematics 2009 conference. While Munich is fine for the English speaking world, it’s München in Germany and Monaco di Baviera to the Italians. But it may also be spelt as Muenchen and Munchen if special characters or accents aren’t used. All of these names are simply multiple versions of the same place, and so are mapped to a single WOEID, 676757.
