Introduction to Yahoo! APIs, tools, YDN and YQL

1. Yahoo! open stack
and YQL

2. To build a web hack
you need three
things:

3. 1. Data
2. Access
3. Interface

4. Yahoo! has opened
up its data

5. http://developer.yahoo.com/everything.html

6. Also others

7. ProgrammableWeb.Com – 3517 APIs

8. The trouble with data:
• You need to find data API
• Get Access – Signup for key
• Find data endpoint
• Read docs to learn what parameters you
have
• Get data in obscure format
• Use data after converting and filtering
• More APIs you use, more is your
annoyance

9. To make data
accessible, Yahoo!
created YQL

10. YQL: http://developer.yahoo.com/yql/console

11. YQL turns web
services and data
on the web into
databases.

12. select {what} from {where}
where {conditions}

13. You can select, filter,
sort and limit data
and you can even
insert, update and
delete from it.

14. Let’s see it

20. YQL has more to it

21. There’s also Yahoo
Pipes to do this visually

22. http://pipes.yahoo.com/

23. Data however is not
enough.

24. You also need
working interfaces

25. Technologies are
easy: HTML, CSS,
Javascript

26. Making it work on
all browsers and OS
is tricky

27. So, we have YUI!

28. http://developer.yahoo.com/yui

29. What about reach?

30. You can build and
wait for people to
come

31. Or build where
people are already
there

32. YAP
http://developer.yahoo.com/yap

33. Some great
resources

34. http://developer.yahoo.com
