Unofficial JDA (Javascript Dataflow Architecture) Wiki

Yahoo has a standard format on their json return data, a little bit like google data. This is a generic blueprint which generates a more manageable output array for html inclusion.

Demos that use it

• map.html
• yahoosearch.html
• multi_map.html
