ActivityPub is an open, decentralized social networking protocol based on Pump.io's ActivityPump protocol. [1] It provides a client/server API for creating, updating, and deleting content, as well as a federated server-to-server API for delivering notifications and content. [2]

Contents

Project status

ActivityPub is a standard for the Internet in the Social Web Networking Group of the World Wide Web Consortium (W3C). The standard was co-authored by Evan Prodromou, [3] creator of StatusNet (now known as GNU social). At an earlier stage, the name of the protocol was "ActivityPump", but it was felt that ActivityPub better indicated the cross-publishing purpose of the protocol. It is the most widely supported standard (by some margin) in the Fediverse.[ citation needed ]

In January 2018, the World Wide Web Consortium (W3C) published the ActivityPub standard as a Recommendation. [2] Lead author Christine Lemmer-Webber notes that the team predominantly identified as queer, which led to features that help users and administrators protect against "undesired interaction." She also notes that the team authoring ActivityPub had no corporate participation. [4]

The W3C Social Community Group previously organized a yearly free conference called ActivityPub Conf about the future of ActivityPub. [5] [6]

Former Diaspora community manager Sean Tilley wrote an article that suggests ActivityPub protocols may eventually provide a way to federate Internet platforms. [7]

Triages are held regularly to review issues pertaining to the ActivityPub and ActivityStreams 2.0 specifications as part of the W3C Social Web Incubator Community Group. [8]

Markdown is a lightweight markup language for creating formatted text using a plain-text editor. John Gruber and Aaron Swartz created Markdown in 2004 as a markup language that is intended to be easy to read in its source code form. Markdown is widely used for blogging and instant messaging, and also used elsewhere in online forums, collaborative software, documentation pages, and readme files.

<span class="mw-page-title-main">OpenSocial</span> Public specification aimed at social networking applications

OpenSocial is a public specification that outlines a set of common application programming interfaces (APIs) for web applications. Initially designed for social network applications, it was developed collaboratively by Google, MySpace and other social networks. It has since evolved into a runtime environment that allows third-party components, regardless of their trust level, to operate within an existing web application.

A distributed social network or federated social network is an Internet social networking service that is decentralized and distributed across distinct service providers, such as the Fediverse or the IndieWeb. It consists of multiple social websites, where users of each site communicate with users of any of the involved sites. From a societal perspective, one may compare this concept to that of social media being a public utility.

<span class="mw-page-title-main">OStatus</span> Open microblogging protocol

OStatus is an open standard for federated microblogging, allowing users on one website to send and receive status updates with users on another website. The standard describes how a suite of open protocols, including Atom, Activity Streams, WebSub, Salmon, and WebFinger, can be used together, which enables different microblogging server implementations to route status updates between their users back-and-forth, in near real-time.

WebRTC is a free and open-source project providing web browsers and mobile applications with real-time communication (RTC) via application programming interfaces (APIs). It allows audio and video communication to work inside web pages by allowing direct peer-to-peer communication, eliminating the need to install plugins or download native apps.

pump.io was a general-purpose activity streams engine that can be used as a federated social networking protocol which "does most of what people really want from a social network". Started by Evan Prodromou, it is a follow-up to GNU social, and is designed tobe more lightweight and usable for general data instead of just microblogging. The largest StatusNet instance at the time, Identi.ca, which was the largest StatusNet service and ran by Prodromou, switched to pump.io in June 2013.

<span class="mw-page-title-main">Pixelfed</span> Open source photo-sharing platform

Pixelfed is a free and open-source image sharing social network service. Unlike many other image sharing services, Pixelfed’s architecture is decentralized and user data is not stored on a central server. Pixelfed uses the ActivityPub protocol which allows users to interact with other social networks within the protocol, such as Mastodon, PeerTube, and Friendica. Using this protocol makes Pixelfed a part of the Fediverse. The network is made up of several independent sites that communicate with one another, which is roughly comparable to e-mail providers. The parties involved do not all have to be registered with the same provider, but can still communicate with each other. Thus, users are able to sign up on any server and follow others on the other instances.
