"LinkML Schema representation of ActivityPub. Contribute to p2p-ld/linkml-activitypub development by creating an account on GitHub." At the time the bookmark was created, this was actually an AS2-only schema, not ActivityPub.

Links to historical versions of the AS2 JSON-LD context document.

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.
