The Yahoo Query Language, or short YQL is a unified interface language to the web.

http://developer.yahoo.com/yql/

select {what} from {source} where {conditions} | {filters}

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

For example:

select * from geo.places where text='london,uk'

Get only the where on earth ID

select woeid from geo.places where text='london,uk'

Then mix:

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

Then mix:

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

And get all the info...

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)
