- In terms of DSpace as a sustainabile, supporting application stack for the Research Exchange service, I found one article, "The DSpace Open Source Digital Asset Management System" to be extremely relevant. It's remarkable to read the story of the development of the DSpace community and to juxtapose that with the list of production DSpace instances and the range of local DSpace software development projects currently underway.
- One article that I re-read for this presentation is "Resource Harvesting within the OAI-PMH Framework" from D-Lib Magazine. This point, early in the article, illustrates the challenges of performing digital content harvesting using OAI-PMH:
Because Dublin Core records are typically created for provision of user services, in many cases a network location provided in dc.identifier is that of a page that provides a link to the resource—a so-called splash-page—not that of the resource itself. In these cases, issues that arise include determining
whether the dereferenced object is actually the resource or a proxy for it,and—if it is a proxy—trying to find the embedded link that leads to the actual resource.
This challenge exists with the DSpace software tool, as illustrated with this Research Exchange item. There is a URI for the item (the item page), but not for the individual bitstreams. - One current DSpace project is the California Digital Library's effort to build support for the Archival Resource Key (ARK) as a DSpace system identifier. This is intriguing because of my institution's work with the ARK scheme in the locally-hosted Northwest Digital Archives database. Read the ARK information and John Kunze's article to obtain info on the strengths of the ARK, which approaches digital sustainability as a matter of service.

sustainability and digital repositories
I'll be presenting tommorow morning at the WSU Sustainability Forum. Some points from my planned presentation:
