OStatus is an open standard for distributed status updates, which references a suite of open protocols including Atom, Activity Streams, PubSubHubbub, Salmon, and WebFinger. 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, although Identi.ca later switched to pump.io. As of June 2013, a number of other microblogging applications and content management systems had announced that they intended to implement the standard.
In January 2012, a W3C Community Group was opened to maintain and further develop the standard. However, this was eclipsed by the work of the W3C Federated Social Web Working Group, launched in July 2014. A newer standard called ActivityPub, based on the protocols used in pump.io, has been identified as a likely successor to OStatus.
