BioMed Central is using its experience as an open access publisher to provide a hosted repository service, Open Repository, that is built on top of DSpace. The goal of Open Repository is to allows organizations to operate a robust, flexible and customizable digital respository service, based on an industry standard platform, without needing a large investment in IT infrastructure and staffing. To make Open Repository possible, BioMed Central has modified Dspace code to allow for efficient hosting of multiple repositories on a single server - we plan to contribute these changes back to the DSpace project. We are also extending DSpace with modules offering extra functionality for Open Repository users, including enhanced access statistics, automatic population of repositories with open access articles, and dynamic rendering of structured XML articles.
