From the document's Introduction: The Open Publication Distribution System (OPDS) Catalog format is a syndication format for electronic publications based on Atom [RFC4287] and HTTP [RFC2616]. OPDS Catalogs enable available electronic publications to be: * discovered, using optional search or a range of optional browsing techniques * acquired, using direct downloads, lending, or vending An OPDS Catalog is a set of one or more Atom Feeds, which are themselves listings of Atom Entries. The Atom Feeds that make up all OPDS Catalogs can be divided into two groups: Navigation Feeds, which create a hierarchy for browsing, and Acquisition Feeds, which list available electronic publications. Each Atom Entry in an Acquisition Feed includes basic metadata about the publication, the publication's format, and how the publication can be acquired. These included Atom Entries may be minimal subsets of the complete metadata, with a link to a more extensive, standalone representation URI (see the Section Listing Acquisition Feeds for more). YACS (Yet Another Catalog Specification), but I do see how it could be helpful. -- Eric Morgan
