Complete ActivityStreams-based ontologies plus middleware handlers implementing ActivityPub

go get github.com/go-fed/activity

This repository contains two libraries and a tool:

• astool: A linked-data aware tool to generate golang native types for any ActivityStreams vocabulary.
• streams: The ActivityStreams native types generated with the astool.
• pub: ActivityPub Social Protocol (Client-to-Server or C2S) and Federating Protocol (Server-to-Server or S2S)

Check out go-fed.org for tutorials and documentation.

Status

This library has been successfully used to federate since May 17, 2019.

An official implementation report was last submitted for version 0.2.0 here. Unfortunately, the official implementation report tool is no longer maintained. Previous unofficial implementation reports are available in issue #46.

Please see CHANGELOG for changes between versions.

Also, see astool, streams, or pub for their own README.

FAQ

What vocabularies are supported?

• ActivityStreams.
• A subset of the toot vocabulary.
• A subset of the security vocabulary.
• ForgeFed.

How well tested are these libraries?

I took great care to add numerous tests using examples directly from specifications, official test repositories, and my own end-to-end tests.

v1.0.0 has around 200 unit tests. The federation or S2S portion of the library is very well tested. The social or C2S portion could use additional unit tests, but is far less popular than federation. About 70% of the lines are covered by unit tests.

Who is using this library currently?

I would like to thank those that have worked hard to create the technologies and standards that created the opportunity to implement this suite of libraries.

Thanks to those who have been early adopters with v0 and/or provided early feedback.
