YQL
(aNd iTs hOtNeSs) Yahoo! calls it: A “mediator service” that
enables developers to
query, filter, and combine
data across Yahoo! and
beyond. I call it: An API for the
public internet.

YQL???????

->SQL-Like Language
->Synonymous with Data access
->Familiar to developers
->Expressive enough to get the right
data.
->Self Describing - show, desc table
->Allows you to query, filter and join
data across WebServices. YQL Statement Basics SYNTAX


SELECT what
FROM collection
WHERE filter condition
IN (sub-select)
LIMIT n OFFSET n hello

format in web?????? The web is full of
juicy and
long lasting
