I've been getting increasingly concerned about what I see as a too-shallow view of sustainability in digital preservation. There's been a lot of lip service paid over the last few years to preservation, and I have certainly heard talks by grant-funding agencies in which they explained that they are now only funding grants which have sustainability written into the grant structure. Yet time and time again, I see soft money being awarded to projects for which the project administrators clearly have only the vaguest idea of what sustainability really means in a software environment.I don't see this as anyone's fault, mind you. Software developers and IT folks aren't used to thinking of software projects in terms of Permanence. In the traditional software world, the only way something is going to be around forever is if it's going to be used all that time -- for example, a financial application which is in constant use needs to be constantly up. But archival digital preservation has a very different sense of permanence. For us, permanence might mean that you build a digital archival collection once, don't touch its content again for 10 years, but can still discover all of its preserved content at the end of those 10 years.
Meanwhile, in Internet time, a project which has been around for two years is clearly well past its prime and ready to be retired.
Repository managers are putting all of this great work into the repository layer* of preservation: handles and DOIs, PRESERV and PRONOM, JHOVE and audit trails and the RLG checklist. But meanwhile, all of these collections of digital objects -- many of them funded by limited-duration soft money -- are running on operating systems which will need to be upgraded and patched as time passes, on hardware which will need to be upgraded and repaired as time passes, on networks which require maintenance. Software requires sustenance and maintenance, and no project which doesn't take into account that such maintenance requires skilled technical people in perpetuity can succeed as perpetual preservation. Real sustainability means commitment from and communication with the programmers and sysadmins. It requires the techies understand an archivist's notion of "permanence", and the librarians and archivists (and grant agencies) understand how that a computer needs more than electricity to keep running -- it needs regular care and feeding.
(This, by the way, is one of the reasons I'm so excited by the OTW Archive of One's Own and the Transformative Works and Cultures journal. The individuals responsible for the archive and the journal *do* have a real understanding of and commitment to permanence down to the hardware and network provider level. Admittedly, it's a volunteer-run, donation supported organization, so its sustainability is an open question. But it's a question the OTW Board is wholeheartedly investigating, because they understand its importance.)
*I'm somewhat tempted to make an archival model of preservation that follows the layered structue of the OSI model of network communication. Collection policy layer, Accession layer, Content layer, Descriptive Metadata layer, Preservation Metadata layer, Application Layer, Operating System layer, Hardware layer. Then you could make sure any new preservation project has all of those checkboxes ticked. Sort of an uber-simplification of the RLG Checklist, in a nice, nerd-friendly format.
