JSON Schema definitions for Fediverse protocols and specifications. Includes schema for ActivityStreams 2, ActivityPub, Mastodon and JRD (Webfinger, nodeinfo)

(Dec 2008) Discussion of Activity Streams directions.

An old video explaining Activity Streams long before AS2 or ActivityPub.

Test suite linked to AS2 specification. It's just a group of files extracted from examples in the spec. It's not clear to me what testing is done.

(2016) Early (pre-ActivityPub) Activity Streams 2.0 library to demonstrate AS2 features.

A very interesting meeting on Activity Streams 2.0 topics. Discussed JSON-LD versus JSON, JSON Schema, AS2 context versioning, AS2 extension registries, AS2 test suite, Linked Data Paging versus AS2 collection paging, and other topics.

An early attempt at creating an Activity Streams test suite.

Interesting discussion about the relationship between Linked Data Paging (LDP) and Activity Streams. Ultimately, the suggestion to unify the two of them was rejected.

Discussion of the issue with Link|anyURI usage in the AS2 specification and the problems it can cause.

An old but interesting pre-specification document describing a variety of potential use cases for ActivityStreams 2.0.
