The ActivityPub protocol is a decentralized social networking protocol based upon the [ActivityStreams] 2.0 data format. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content.

In the most basic sense, an "Activity" is a semantic description of an action. It is the goal of this specification to provide a JSON-based syntax that is sufficient to express metadata about activities in a rich, human-friendly but machine-processable and extensible manner. This can include constructing natural-language descriptions or visual representations about the activity, associating actionable information with various types of objects, communicating or recording activity logs, or delegation of potential actions to other applications.

Linked Data Notifications is a protocol that describes how servers (receivers) can have messages pushed to them by applications (senders), as well as how other applications (consumers) may retrieve those messages. Any resource can advertise a receiving endpoint (Inbox) for the messages. Messages are expressed in RDF, and can contain any data.

The Resource Description Framework (RDF) is a general-purpose language for representing information on the Web. This document defines a textual syntax for RDF called Turtle that allows an RDF graph to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes. Turtle provides levels of compatibility with the N-Triples [N-TRIPLES] format as well as the triple pattern syntax of the SPARQL W3C Recommendation.

This document includes errata for the Activity Streams and Activity Vocabulary documents.

A little misleading since it doesn't actually list any errors (and they are there), but it's where they will go. There is also a link to the proposed errata.

A list of non-normative tutorials and commentary about Activity Streams topics. This is sometimes useful for understanding some of the quirks of the specification.

This page exists to document extensions to the ActivityPub protocol. Extensions are developed as part of the SWICG.

This page documents known AS2 extensions and best practices for using other namespaces in AS2.

This document lists the terms used for the ActivityStreams 2.0 protocol and its stable extensions, and provides a namespace so each term has an HTTP IRI. This document is merely a W3C-internal document. It has no official standing of any kind and does not represent consensus of the W3C Membership.
