Overview

The project is split in two phases that will be carried out successively during a 3-year time frame. A side objective is to coordinate the roadmap with the formal release of the ANSI/NISO DAISY Z39.86-2010 revision as a NISO standard in mid 2011.

The project will span over 42 months (3.5 years) and focus on delivering iterative releases on a regular schedule (every 6 months), with additional intermediary milestones for the finalization of each phases. See also the project charters for a description of the work items and tentative milestones.

History

Inception Phase

The inception phase will span over the first few months of the project, most probably till the end of 2009. Its objectives are mostly to identify key use case scenarios and requirements, evaluate key technologies, and draft an overall architectural design coherent with the technologies selection.

Mid December 2009: review of the existing project proposal
End of January 2010: draft charter (technical details not yet resolved can be mentioned)
Early February 2010: call for formal participation commitment
March 2010: finalization of the charter
End of March 2010: finalized charter sent to the board

Q4 2010

November 17-19, 2010: F2F in Zurich
December 23, 2010: Early Preview Release

Q1/Q2 2011

Milestones

Mid-April (e.g. week #15 or #16): F2F
Beta 1 released on May 20, possibly followed by others till June 3 (2 weeks after).

ZedAI to EPUB3

note: depending on EPUB3 (public draft on February 14th)
=> mid-Feb: identify remaining steps and utility modules
=> mid-April (f2f): early EPUB3 production

ZedAI to DTBook

TBD: when to start ? (should be easier after ZedAI to HTML and DTBook to ZedAI)

DAISY 2.02 to EPUB3 (optional)

TBD: when to start ?

Q2 2011
