The Yahoo! Blueprint Platform includes an easy-to-use tool kit that allows you to focus on building content and services into your mobile widget. It’s based on Blueprint, Yahoo!’s versatile XML-based programming language that allows you to build widgets that will run on hundreds of devices.

The Blueprint SDK includes three key components:

  • Blueprint Developer's Guide
  • XML Schema Definitions
  • Mobile Widget Sample Code

These components give you everything you need to create a mobile widget, including information on widget testing and publishing.
