SWORD is a protocol for depositing content into repositories. It is a lightweight profile of the Atom Publishing Protocol that defines a set of mandatory and optional parameters for repository deposit. The SWORD protocol has been implemented in several repositories including DSpace, EPrints, IntraLibrary and Fedora. It also has several Java client implementations. SWORD aims to provide a standard way for content to be deposited into repositories from a variety of sources through a simple web service interface.
