ActivityPub
ActivityPub is a Communication protocol, protocol and open standard for Decentralised system, decentralized Social networking service, social networking. It provides a Client–server model, client-to-server (C2S) API for creating and modifying content, as well as a Federation (information technology), federated Inter-server, server-to-server (S2S) protocol for delivering notifications and content to other servers. ActivityPub has become the main standard used in the fediverse, a popular network used for social networking that consists of software such as Mastodon (social network), Mastodon, Pixelfed and PeerTube. ActivityPub is considered to be an update to the ActivityPump protocol used in pump.io, and the official W3C repository for ActivityPub is identified as a fork of ActivityPump. The creation of a new standard for Distributed social network, decentralized social networking was prompted by the complexity of OStatus, the most commonly used protocol at the time. OStatus was b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fediverse
The Fediverse (commonly shortened to fedi) is a collection of social networking services that can communicate with each other (formally known as Federation (information technology), federation) using a common protocol. Users of different websites can send and receive status updates, multimedia computer file, files and other data across the computer network, network. The term ''Fediverse'' is a portmanteau of ''federation'' and ''universe''. The majority of Fediverse platforms are based on free and open-source software, and create connections between servers using the ActivityPub protocol. Some software still supports older federation protocols as well, such as OStatus, the Diaspora (social network), Diaspora protocol and Zot. Diaspora* is the only actively developed software project classified under the original definition of ''Fediverse'' that does not support ActivityPub. Design While a traditional social networking service will host all its content on servers managed by the own ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mastodon (social Network)
Mastodon is a free and open-source software platform for decentralized social networking with microblogging features similar to Twitter. It operates as a federated network of independently managed servers that communicate using the ActivityPub protocol, allowing users to interact across different instances within the Fediverse. Each Mastodon instance establishes its own moderation policies and content guidelines, distinguishing it from centrally controlled social media platforms. First released in 2016 by Eugen Rochko, Mastodon has positioned itself as an alternative to mainstream social media, particularly for users seeking decentralized, community-driven spaces. The platform has experienced multiple surges in adoption, most notably following the Twitter acquisition by Elon Musk in 2022, as users sought alternatives to Twitter. It is part of a broader shift toward decentralized social networks, including Bluesky and Lemmy. Mastodon emphasizes user privacy and moderation ...

Pleroma (software)
Pleroma is a Free and open-source software, free and open-source microblogging social networking service. Unlike popular microblogging services such as Twitter or Weibo, Pleroma can be Self-hosting (web services), self-hosted and operated by anyone with a Server (computing), server and a Domain name, web domain, a combination commonly referred to as an instance. Instance administrators can manage their own code of conduct, terms of service, and Content moderation, content moderation policies, allowing users to have more control over the content they view as well as their experience. It was named after the religious concept of pleroma, or the totality of divine powers. The software also implements the ActivityPub protocol, which allows users to communicate and interact with content from other Pleroma instances or any server that is running software that supports ActivityPub (such as Mastodon (social network), Mastodon, Misskey, Pixelfed, etc.), a Decentralised system, decentralize ...

Pixelfed
Pixelfed is a free and open-source image sharing social network service. The platform uses a decentralized architecture which is roughly comparable to e-mail providers, meaning user data is not stored on one central server. It uses the ActivityPub protocol, allowing users to interact with other social networks within the protocol, such as Mastodon, PeerTube, and Friendica. Pixelfed and other platforms utilizing this protocol are considered to be part of the Fediverse. Much like Mastodon, Pixelfed implements chronological timelines without content manipulation algorithms. It also aims to be privacy-focused with no third party analytics or tracking. Pixelfed optionally organizes its media by hashtags, geo-tagging and likes based on each server. It also allows audiences to be distinguished in three ways and on a post-by-post basis: followers-only, public, and unlisted. Like several other social platforms, Pixelfed allows accounts to be locked, when followers must be pre-approved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AT Protocol
The AT Protocol (Authenticated Transfer Protocol, pronounced " @ protocol" and commonly shortened to ATProto) is a protocol and open standard for distributed social networking services. It is under development by Bluesky Social PBC, a public benefit corporation originally created as an independent research group within Twitter, Inc. to investigate the possibility of decentralizing the service. The AT Protocol aims to address perceived issues with other decentralized protocols, such as user experience, platform interoperability, discoverability, network scalability, and portability of user data and social graphs. It employs a modular microservice architecture and a federated, server- agnostic user identity to enable movement between protocol services, with the goal of providing an integrated online experience. Platforms can access and serve any user content within the network by fetching content formatted as predefined data schemas from federated network-wide dat ...

Microblogging
Microblogging is a form of blogging using short posts without titles known as microposts or status updates. Microblogs "allow users to exchange small elements of content such as short sentences, individual images, or video links", which may be the major reason for their popularity. Some popular social networks such as Twitter, X (Twitter), Threads (social network), Threads, Tumblr, Mastodon (social network), Mastodon, Bluesky and Instagram can be viewed as collections of microblogs. As with traditional blogging, users post about topics ranging from the simple, such as "what I'm doing right now", to the thematic, such as "sports cars". Commercial microblogs also exist to promote websites, services, and products and to promote collaboration within an organization. Some microblogging services offer privacy settings, which allow users to control who can read their microblogs or alternative ways of publishing entries besides the web-based interface. These may include text messaging, ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OStatus
OStatus is an open standard for decentralized social networking, allowing users on one service to send and receive status updates with users from another. The standard describes how a suite of various standards, including Atom, Activity Streams, WebSub, Salmon, and WebFinger, can be used together, which enables different microblogging server implementations to communicate status updates between their users back-and-forth, in near real-time. History OStatus federation was first possible between servers running StatusNet, 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. That same month, it was announced StatusNet would be merged into the GNU social project along with Free Social, a similar application itself forked from StatusNet. Following the first official release of GNU Social, a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU Social
GNU social (and its predecessor StatusNet) is a largely defunct free and open-source microblogging social networking service that implements the OStatus and ActivityPub standards for interoperability between installations. While offering similar functionality to social networks such as Twitter, GNU social seeks to provide the ability for open and federated communication between different microblogging communities, known as 'instances'. Both enterprises and individuals can install and control their own instances and user data.Bastien, Malcolm (2008-8-28Why Laconica Means Big Things For Corporate Micro Blogging. Retrieved 2009-1-3. At its peak in popularity, GNU social had been deployed on hundreds of interconnected instances, however has since fallen into disuse as competing software like Mastodon and Pleroma have taken its position as the dominant federated microblogging services. Later on in its lifespan, the project split into two separate branches, with "v2" being a continuatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Distributed Social Network
A distributed social network (more recently referred to as a federated social network) is a network wherein all participating social networking services can communicate with each other through a unified communication protocol. Users that reside on a compatible service can interact with any user from any compatible service without having to log on to the origin's website. From a societal perspective, one may compare this concept to that of social media being a public utility. Federated social networks contrast with social network aggregation services, which are used to manage accounts and activities across multiple discrete social networks that cannot communicate with each other. A popular example for a federated social network is the fediverse, with more niche examples such as IndieWeb complementing the network. Services that want to natively connect into a federated social network need to be interoperable with both the majority of content that the network produces (eithe ...

JSON-LD
JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding linked data using JSON. One goal for JSON-LD was to require as little effort as possible from developers to transform their existing JSON to JSON-LD. JSON-LD allows data to be serialized in a way that is similar to traditional JSON. It was initially developed by the JSON for Linking Data Community Group before being transferred to the RDF Working Group for review, improvement, and standardization, and is currently maintained by the JSON-LD Working Group. JSON-LD is a World Wide Web Consortium Recommendation. Design JSON-LD is designed around the concept of a "context" to provide additional mappings from JSON to an RDF model. The context links object properties in a JSON document to concepts in an ontology. In order to map the JSON-LD syntax to RDF, JSON-LD allows values to be coerced to a specified type or to be tagged with a language. A context can be embedded directly in a JSON-LD document or put in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
