Journal tags: geotagging

Back in March, during South by Southwest, Tantek asked me if I’d like to sit in on his microformats panel alongside Chris Messina and Norm! The audio recording of the panel is now available through the conference podcast.

I’ve taken the liberty of having the recording transcribed (using castingWords.com) and I’ve posted a tidied up version of the transcript to the articles section: Microformats: Evolving the Web. You can listen along through the articles RSS feed which doubles up as a podcast.

I’ve also posted the transcript on the microformats wiki so that others can edit it if they catch any glaring mistakes in the transcription.

During the panel I talked about Adactio Austin, a fairly trivial use of microformats but one that I’ve been building upon. I’d like to provide some cut’n’paste JavaScript that would allow people to get some added value from using microformats. Supposing you have a bunch of locations marked up in hCard with geotags, you could drop in a script and have a map appear showing those locations.

Perhaps the geotagging won’t even be necessary. Google added a geocoder to their mapping API two weeks ago. The UK, alas, is not yet supported (probably because the Post Office won’t let go of its monopoly that easily… Postman Pat, your money-grabbing days are numbered).

Unfortunately, Google Maps isn’t very suited to the cut’n’paste idea: you have to register a different API key for each domain where you want to use the mapping API.

The Yahoo maps API is less draconian about registration but its lack of detailed UK maps makes it a non-starter for me.

Maybe I should step away from maps and concentrate on events instead. It probably wouldn’t be too hard too write a script to create a calendar based on any hCalendar data found in a document. Perhaps I’ll investigate the calendar widget from Yahoo.

Ultimately I’d like to create something like Chris’s Mapendar idea. If only there were enough hours in the day.

At the risk of becoming API-watch Central, I feel I must point out some nifty new features that have been added to Upcoming.org.

Andy and the gang have been diligently geotagging events using Yahoo’s geocoder API. Best of all, these latitude and longitude co-ordinates are now also being exposed through the API. Methinks Adactio Austin won’t be the last mashing up of event and map data I’ll be doing.

On the Upcoming site itself, you can now limit the number of attendees for an event, edit any venues you’ve added and edit your comments. This comes just a few days after Brian Suda mentioned in a chat that he would like to have the option to edit this comment later (right now he’s looking for somewhere to stay during XTech).

Feature wished for; feature added. This is exactly the kind of iterative, evolutionary growth that goes a long way towards what Kathy Sierra calls creating passionate users. By all accounts, her panel at South by Southwest was nothing short of outstanding. Everyone I spoke to who attended was raving about it for days. Muggins here missed it but I have a good excuse. I was busy signing freshly-purchased books, so I can’t complain.
