Other Web Annotation Projects

Advene

The Advene project (Annotate Digital Video, Exchange on the NEt) aims at providing a model and a format to share annotations about digital video documents (movies, courses, conferences...), as well as tools to edit and visualize the hypervideos generated from both the annotations and the audiovisual documents.

• repo: https://github.com/oaubert/advene GPLv2

Elucidate is a Web Annotation server that is compliant with both the W3C Web Annotation Data Model and associated protocol, and the Open Annotation (OA) Data Model.

Recagito

Semantic Annotation Without the Pointy Brackets

• repo: https://github.com/pelagios/recogito2 Apache-2.0
• exports Web Annotations

Simple Annotation Server

This is a very simple annotation server intended for testing purposes, implementing both the Web Annotation Protocol as well as the Web Annotation Data Model with simple REST-based user management. The server is written in JavaScript and runs in Node.js, running an in-process LevelDB database.

• MIT licensed
• Gerben’s web-annotation-discovery-server (see below) is a fork of this.

Web Annotation Discovery

(note I’m adding my own project here, for completeness)

a simple mechanism for using Web Annotation in web browsers. The envisioned outcome is that people can discover annotation sources and subscribe to annotation ‘feeds’ while browsing the web, then view the annotations on other pages they visit.

• By Gerben (Apache Annotator committer)
• Includes a server based on simple-annotation-server (see above), and a browser extension.
