As one element of finalizing the planned combination of IDPF with W3C, IDPF anticipates submitting EPUB 3.1 to W3C as a W3C Member Submission. IDPF and W3C would like all organizations that contributed to the development of EPUB specifications to co-sign IDPF's member submission. This will facilitate the transfer of this important intellectual property and memorialize your organization's contributions to a critical open standard.
An authorization, which includes a draft of the cover for the prospective submission, is located at http://idpf.org/sites/default/files/EPUB_3_1_authorization_with_cover.pdf
This request for co-signers is applicable to all current and former IDPF member organizations that contributed to any version of EPUB (including contributions to extension specifications that were subsequently incorporated into EPUB). Please note that, as provided in the authorization, the prospective submission will take place if and only if the combination of IDPF with W3C is finalized as planned.
If your organization contributed to the development of EPUB specifications, please sign the submission authorization at your earliest convenience (but no later than December 21, 2016), and email a scan of the signed authorization to email@example.com (or remit by physical mail to IDPF, 113 Cherry St. Ste 70-719 Seattle, WA 98110 USA).
