The Yahoo Query Language, or short YQL is a unified interfacelanguage 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.searchwhere 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 datain JavaScript.

Re-mixing the web.

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

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

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

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

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