Bill McCoy, General Manager of ePublishing Business at Adobe Systems, has announced the release of a draft version of the Open Publication Distribution System.
Here's an excerpt from the announcement:
Stanza, the leading iPhone eBook software, includes an excellent online catalog system that enables users to seamlessly acquire free and commercial content from within the application. The Lexcycle team built this system in an open, extensible manner using Atom. Adobe and Lexcycle have been working together on Adobe PDF and EPUB eBook support, and now we are deepening that collaboration in working together, along with the Internet Archive and others, to establish an open architecture enabling widespread discovery, description, and access of book and other published material on the open web. The Open Publication Distribution System (OPDS) is a generalization of the Atom approach used by Stanza's online catalog. I'm grateful to the Lexcycle team as well as my friend and colleague Peter Brantley for their efforts on behalf of open access and interoperability.
