Hello,

On behalf of the OPDS community, I am able to announce that the draft 
1.0 specification of the BookServer OPDS Catalog is available for 
review at http://code.google.com/p/openpub/wiki/CatalogSpecDraft.

We are soliciting feedback and comments on this version 1.0 draft.

Please submit 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 Tuesday, 17 August 
2010.

Version 0.9 the OPDS Catalog specification was published on 25 May 
2010: http://opds-spec.org/specs/opds-catalog-0-9.

What are OPDS Catalogs?

OPDS stands for "Open Publication Distribution System".  OPDS 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.

Today, OPDS Catalogs power many existing, in-production software 
systems and distribution between ebook reading systems, publishers, 
and distributors. Feedbooks, for example, already 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 OPDS Catalogs as the specification has evolved toward 1.0.

OPDS Catalogs are the first component in the Internet Archive’s 
BookServer Project (http://www.archive.org/bookserver).  BookServer 
was prominently discussed in the recent COSLA report on ebook 
strategies for public libraries 
(http://www.cosla.org/documents/COSLA2270_Report_Final1.pdf).
