Yahoo Application Platform (YAP) allows developers to build applications that integrate with Yahoo services and reach Yahoo's large audience. YAP applications can be small widgets with limited capabilities or full-featured applications that run in an iframe. YAP supports Yahoo Markup Language (YML) to easily add social features and access user data through Yahoo APIs. Developers are encouraged to use YAP to create engaging social applications that take advantage of Yahoo's social graph and large user base.
