This module discusses SWORD clients, which allow users to deposit items into repositories through a graphical interface rather than directly interacting with XML files. There are three types of clients: machine-to-machine for automated deposits, general clients that can deposit to any repository, and specific clients tailored for a particular use. Examples of clients include demo clients, the Facebook deposit tool, and Word add-ins. Creating custom clients is made easier by available code libraries for languages like PHP and Java. The module aims to help understand the need for and variety of SWORD clients.
