Yahoo releases the Yahoo! Application Platform (YAP) , Yahoo! Social Platform (YSP) and Yahoo! Query Language (YQL).
Yahoo! Social Platform consists of a suite of REST-based social APIs from Yahoo! including: Profiles, Connections, Updates, Contacts and Status. Yahoo! Query Language (YQL) is a new web service API that lets you access other web services using a SQL-like language rather than typical programmatic access. You can think of it as a command line version of Pipes. Yahoo! Application Platform (YAP) supports a few programming models including:
1. Developer hosted execution of applications with access to Yahoo’s Social APIs and YQL.
2. Support for OpenSocial’s JavaScript API
3. Support for server-side YML tags.
