The Social Web Working Group has published a Proposed Recommendation for three documents:
Micropub: The Micropub protocol is used to create, update and delete posts on one’s own domain using third-party clients. Web apps and native apps (e.g., iPhone, Android) can use Micropub to post and edit articles, short notes, comments, likes, photos, events or other kinds of posts on your own website.
Activity Streams 2.0: This specification details a model for representing potential and completed activities using the JSON format.
Activity Vocabulary: The Activity Streams 2.0 Core Syntax defines the JSON syntax for Activity Streams and a set of abstract types and properties that describe past, present and future Activities. This document defines the vocabulary properties.
Comments are welcome through 15 May 2017.
