Greetings -

OPDS (Open Publication Distribution System) was first launched approximately
one year ago (http://blogs.adobe.com/billmccoy/2009/04/announcing_open.html),
and today the OPDS community is very pleased to announce a call for comments
on the first draft spec version, 0.9.

The OPDS Catalogs 0.9 draft at
http://code.google.com/p/openpub/wiki/CatalogSpecDraft is ready for public
review and we are soliciting feedback and comments.

Please submit any and all critiques or comments to the openpub mailing list
(http://groups.google.com/group/openpub) or add an issue (
http://code.google.com/p/openpub/issues/entry) by *19 May 2010*.

What are OPDS Catalogs?

OPDS Catalogs enable the aggregation, distribution, and discovery of books,
journals, and other digital content by any user, from any source, in  any
electronic format, on any device. The OPDS Catalogs specification is based
on the Atom syndication format and prioritizes simplicity and speed.

Are there any current implementers of this standard?

The OPDS Catalogs 0.9 draft is based on a lot of existing, in-production
software and collaboration between ebook reading systems, publishers, and
distributors. Feedbooks, for example, distributes more than 2 million ebooks
every month using its OPDS Catalogs (http://feedbooks.com/catalog.atom) and
ebook readers like Aldiko, Stanza, QuickReader, FBReader, Ibis Reader, and
others already support the evolving specification. Publishers and libraries
have been early adopters of the OPDS Catalogs as the specification has
evolved toward 0.9 as well.

Some highlights:

* Internet Archive (1.8 million free books,
http://bookserver.archive.org/catalog/)

* O'Reilly Media (hundreds of technical ebooks,
http://catalog.oreilly.com/aldiko/main.xml)

* PragPub Magazine, from The Pragmatic Programmers
(http://pragprog.com/magazines.opds)

* Smashwords
(http://www.smashwords.com/atom)

OPDS Catalogs are the first component in the Internet Archive’s
BookServer Project (http://www.archive.org/bookserver).

Thanks for your feedback,

The openpub community
