The Yahoo Query Language, or short YQL is a unified interface language to the web. http://developer.yahoo.com/yql/

select {what} from {service} where {condition}

Say you want kittens on your site (who doesn’t?) select * from flickr.photos.search where text="kitten"

Say you only want 5 kittens select * from flickr.photos.search where text="kitten" limit 5

Say you only want 5 kittens

Nice, but where can you get this?

http://query.yahooapis.com/v1/ public/yql?q={query} &format={format}

Output formats are XML or JSON. JSON means you can use the data in JavaScript.

http://query.yahooapis.com/v1/public/yql?q=select %20*%20from flickr.photos.search%20where%20text= %22kitten%22limit%205&format=json&callback=meow

Re-mixing the web.

Guess what this does: select * from flickr.photos.info where photo_id in (select id from flickr.photos.search where woe_id in (select woeid from geo.places where text='london,uk') and license=4)

Find London, England select * from flickr.photos.info where photo_id in (select id from flickr.photos.search where woe_id in (select woeid from geo.places where text='london,uk') and license=4)

Find photos from there. select * from flickr.photos.info where photo_id in (select id from flickr.photos.search where woe_id in (select woeid from geo.places where text='london,uk') and license=4)

Get the info of for the photos select * from flickr.photos.info where photo_id in (select id from flickr.photos.search where woe_id in (select woeid from geo.places where text='london,uk') and license=4)

Make sure you are OK to use them! select * from flickr.photos.info where photo_id in (select id from flickr.photos.search where woe_id in (select woeid from geo.places where text='london,uk') and license=4)
