Dspace (via Swannie) is an open source platform that helps institutions archive, manage and distribute “digital works” over the long term. It appears to be a variant on the idea of a content management system, but with a heavy emphasis on academic works and multiple formats. The system is implemented in Java (with a JSP front end) and uses a PostgreSQL for the metadata (based on Dublin Core) and relataional information. The assets can be stored in a variety of ways (filesystems, WebDAV, database BLOBS are all mentioned) via an abstraction layer known as a “bitstream”. The system was developed by MIT and HP and has gone live for use by MIT’s academic departments. Interesting stuff.
