Open Annotation in EPUB

Matt Garrish edited this page Aug 5, 2015 · 1 revision


This project seeks to define how to apply Open Annotations in the context of EPUB, thereby enabling users and service providers to utilize a non-proprietary representation of annotation data.


The Open Annotation in EPUB specification is being developed under the charter of the EPUB 3 Working Group.



The profile reached Draft Specification status on July 23, 2015.

Future Milestones

The next projected milestone is publication as a Proposed Specification in the Fall of 2015.

The profile is expected to reach Recommendation in 2016.

Adoption Readiness Roadmap

An adoption readiness roadmap will be published after the specification reaches Proposed Specification status.




Teleconference calls are held weekly on Wednesdays at 22UTC during periods of active development.

Note: Teleconefereces are currently suspended.

Archived meeting minutes are available.
