Introduction

The basic building block of this proposal is the queryable Atom feed. Each user has their own feed, through which they publish annotations. This proposal includes definitions of:

  1. Extensions to Atom to support publishing of annotations
  2. A protocol for query publishing feeds
  3. Protocols for integrating with web pages


What's Missing

Two areas that we haven't yet given a lot of thought to are:

  1. identifying fragments of a page to which annotations apply.
  2. how individuals publish annotations to their publishing feed.


Background

Comment Anywhere grew out discussions between Alec Thomas and Alan Green about open and distributed social networks. We were pleasantly surprised by the amount of overlap between this proposal and the Original Annotation API Proposal.
