In this paper, we propose a strategy for the automated and scheduled maintenance of a digital library collection. Existing systems require the user either to add new data manually to a collection, or to have programming knowledge in order to use existing application programming interfaces (APIs) in order to automate scheduled collection updates. We incorporate a scheduling module into the Greenstone digital library software, which allows the user to set up scheduled and automated building of a collection at periodic intervals. This module interacts with the task scheduler on the host platform, such as Linux, Windows and Mac OS X, thereby making it a simple yet powerful tool for scheduled collection maintenance.
