YQL is a unified interface language
to the web.
http://developer.yahoo.com/yql/

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

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

29. For example:
select * from geo.places where
text='london,uk'

32. Get only the where on earth ID
select woeid from geo.places
where text='london,uk'

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

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

35. 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)

40. Then display them using frameworks...
