OStatus is an open standard for distributed status updates,[1] which references a suite of open protocols including Atom, Activity Streams, PubSubHubbub, Salmon, and WebFinger.[2] It enables different microblogging messaging hubs to route status updates between users in near real-time.

OStatus federation was first possible between StatusNet installations, such as Status.net and Identi.ca,[3] although Identi.ca later switched to pump.io.[4] As of June 2013, a number of other microblogging applications and content management systems had announced that they intended to implement the standard.[5]

Standards work[edit]

In January 2012, a W3C Community Group was opened to maintain and further develop the standard.[6] However, this was eclipsed by the work of the W3C Federated Social Web Working Group, launched in July 2014.[7] A newer standard called ActivityPub, based on the protocols used in pump.io, has been identified as a likely successor to OStatus.[8]
