Illuminated Hacks -- Where 2.0 101 Tutorial

Illuminated Hacks Mikel Maron Where 2.0 101 Tutorial [email_address] http://brainoff.com/

Some of my favorite hacks for the pleasure of your hacking sensibility with the hopeful outcome of illuminating best practices of putting your website on the geoweb and hinting at the means to get exactly what you need. cause I likes the hacks. hacks are rad.

Machine Tags namespace:predicate=value geobloggers user controlled, just normal tags structured data geo:lat=37.784692 geo:long=-122.39303 geotagged camel:humpcount=1 loosely coupled lastfm:event=97947 iso:isbn=0713998393 http://www.flickr.com/groups/api/discuss/72157594497877875/ http://adactio.com/journal/1274/

machine_tags (Optional) Aside from passing in a fully formed machine tag, there is a special syntax for searching on specific properties : * Find photos using the 'dc' namespace : "machine_tags" => "dc:" * Find photos with a title in the 'dc' namespace : "machine_tags" => "dc:title=" * Find photos titled "mr. camera" in the 'dc' namespace : "machine_tags" => "dc:title=\"mr. camera\" * Find photos whose value is "mr. camera" : "machine_tags" => "*:*=\"mr. camera\"" * Find photos that have a title, in any namespace : "machine_tags" => "*:title=" * Find photos that have a title, in any namespace, whose value is "mr. camera" : "machine_tags" => "*:title=\"mr. camera\"" * Find photos, in the 'dc' namespace whose value is "mr. camera" : "machine_tags" => "dc:*=\"mr. camera\"" Multiple machine tags may be queried by passing a comma-separated list. The number of machine tags you can pass in a single query depends on the tag mode (AND or OR) that you are querying with. "AND" queries are limited to (16) machine tags. "OR" queries are limited to (8). http://www.flickr.com/services/api/flickr.photos.search.html a hack all grown up

http://geothings.ning.com/Flickr/flickrgeocodr_cluster.php to output more detailed information regarding the clusters themselves in REST XML or JSON. You will need to create a query string. The only required key-value pair is "place", and it will use the other values on their default settings. * place = the placename to search for. * format = json|xml (default xml). * searchmode = tags|text (default tags) (text searchs tags, title and description). * sortmode = interestingness-desc|relevance| (or any other values from Flickr API)(default interestingness-desc). * bbox = any min_lon, min_lat, max_lon, max_lat Comma separated, no spaces. Good for limiting to continent / country. (default world -180.0,-90.0,180.0,90.0). * numresults = 5 to 500 (default 50) Number of photo results to process from Flickr, more will slow things down, but may increase sample size, and accuracy. * numclusters = 2 to 20 (default 3) Number of clusters to use internally, experiment with this, I find 3 and 4 fine. * xn_auth =no - a Ning tweak to bypass Ning authenitcation, speeds things up. * showpoints = true|false (defaults to false) Returns photos in each cluster (link to photo, and link url) * showclusters = true|false (defaults to true) format = xml or json (default is xml) http://geocodr.net/FlickrGeocodrDocs.php
