OAuth. For MediaWiki's (the software used by Wikipedia) OAuth support, see mw:Help:OAuth OAuth is an open standard for authorization, commonly used as a way for Internet users to log into third party websites using their Microsoft, Google, Facebook or Twitter accounts without exposing their password.[1] Generally, OAuth provides to clients a 'secure delegated access' to server resources on behalf of a resource owner.
It specifies a process for resource owners to authorize third-party access to their server resources without sharing their credentials. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner.
Open Graph. Facebook Platform. The Facebook Platform[1] is a software environment provided by the social networking service Facebook for third-party developers to create their own applications and services that access data in Facebook.[2] Launched on May 24, 2007, the platform offers a set of programming interfaces and tools which enable developers to integrate with the open "social graph" of personal relations and other things like songs, places, and Facebook pages.
Applications on Facebook.com, external websites, and devices are all allowed to access the graph. History[edit] Third party companies provide application metrics, and several blogs arose in response to the clamor for Facebook applications. On July 4, 2007, Altura Ventures announced the "Altura 1 Facebook Investment Fund," becoming the world's first Facebook-only venture capital firm.[5] OAuth Community Site.
