DSpace and other digital repositories present unique challenges for preservation. They are typically driven by programming languages and don't fall into the usual folder/subfolder/file data structure. Materials can be difficult to extract, so individually-tailored approaches must be used. Both Georgia Tech and Rice belong to the Metaarchive cooperative, a group of schools and museums which have formed a private LOCKSS network (PLN) to do digital preservation. Both schools use DSpace for their digital repositories. For various reasons, the LOCKSS software does not easily harvest materials out of DSpace. Both schools were able to overcome these issues and deposit materials into the Metaarchive network. By collaborating and working through the cooperative, each school came up with a different approach.
