Annotator Roadmap

This document lays out the planned schedule and roadmap for the future development of Annotator.

For each release below, the planned features reflect what the core team intend to work on, but are not an exhaustive list of what could be in the release. From the release of Annotator 2.0 onwards, we will operate a time-based release process, and any features merged by the relevant cutoff dates will be in the release.


This is a living document. Nothing herein constitutes a guarantee that a given Annotator release will contain a given feature, or that a release will happen on a specified date.


What will be in 2.0

  • Improved internal API
  • UI component library (the UI was previously “baked in” to Annotator)
  • Support (for most features) for Internet Explorer 8 and up
  • Internal data model consistent with Open Annotation
  • A (beta-quality) storage component that speaks OA JSON-LD
  • Core code translated from CoffeeScript to JavaScript


The following dates are subject to change as needed.

April 25, 2015 Annotator 2.0 alpha; major feature freeze
August 1, 2015 Annotator 2.0 beta; complete feature freeze
September 15, 2015 Annotator 2.0 RC1; translation string freeze
2 weeks after RC1 Annotator 2.0 final (or RC2 if needed)

The long period between a beta release and RC1 takes account of time for other developers to test and report bugs.


The main goals for this release, which we aim to ship by Jan 1, 2016 (with a major feature freeze on Nov 15):
