OStatus

 OStatus  is a suite of protocols for distributed social networking: Atom ActivityStreams, PubSubHubbub, Salmon, WebFinger per https://twitter.com/kevinmarks/status/365560040326840320 / Evan Prodromou, who later went on to develop pump.io, which itself is being superseded by ActivityPub.

IndieWeb Equivalents
Here's a table of OStatus technologies and current IndieWeb equivalents that are being adopted:

Related (semi-generationally) but not officially part of OStatus:
 * OpenID and IndieWeb equivalent: IndieAuth

The indieweb equivalents are typically a subset and do not achieve the same levels of functionality as the OStatus technologies, however the indieweb equivalents are what's been developed so far to meet current use-cases.

Site Death
The main OStatus site ostatus.org died on 2012-10-09 when it was redirected to the W3C OStatus Community Group, and apparently all posts and other information on ostatus.org was lost. Some content from the OStatus wiki at status.net/wiki/OStatus (defunct URL) was ported to the W3C OStatus Community Group wiki.


 * 2012-10-08 last archive of ostatus.org home page
 * https://web.archive.org/web/20121009153129/http://ostatus.org/ 2012-10-09 first redirect to W3C Community Group

Eventually ostatus.org expired (when? 2018-09 or earlier) and was squatted (when? 2018-09 or earlier) - the current site is unrelated to the original.
