openpub - Project Hosting on Google Code. an application of the Atom Syndication Format intended to enable content creators and distributors to distribute digital books via a simple catalog format. The mechanism through which compatible Reading Systems access the distributed catalog has three components: eBook content, XML catalog metadata, and an HTTP transport for the catalog. OPDS-compatible Reading Systems must support IDPF EPUB, and may optionally support additional formats.
SWORD is a lightweight protocol for depositing content from one location to another. It stands for Simple Web-service Offering Repository Deposit and is a profile of the Atom Publishing Protocol (known as APP or ATOMPUB). SWORD has been funded by the Joint Information Systems Committee to develop the SWORD profile and a number of demonstration implementations. The SWORD vision is 'lowering the barriers to deposit', principally for depositing content (any content!) into repositories, but potentially for depositing into any system which wants to receive content from remote sources.
