Social Web Bookmarks

"Occasionally there are online discussions about using schema.org vocabularies with ActivityPub (AP) and Activity Streams 2.0 (AS2). There are many ways to do this, but this article will explore one approach..."

Interesting discussion about informal alternatives to JSON-LD. Some of the most interesting material is in the comments (by Sporny).

"This specification details a model for representing potential and completed activities using the JSON format."
A draft AS2 specification prior to the W3C Social WG. This one uses JSON, whereas the final AS2 specification uses JSON-LD.

List of user stories considered by the original AS2/SocialWG team (c. 2015).

Original Activity Streams (and related) submission by opensocial.org to the W3C SocialWG. This is interesting from an historical perspective.

"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.
