Unsupervised creation of small world networks for the preservation of digital objects

The prevailing model for digital preservation is that archives should be similar to a “fortress”: a large, protective infrastructure built to defend a relatively small collection of data from attack by external forces. Such projects are a luxury, suitable only for limited collections of known importance and requiring significant institutional commitment for sustainability. In previous research, we have shown the web infrastructure (i.e., search engine caches, web archives) refreshes and migrates web content in bulk as side-effects of their user-services, and these results can be mined as a useful, but passive preservation service. Our current research involves a number of questions resulting from removing the implicit assumption that web-based data objects must passively await curatorial services: What if data objects were not tethered to repositories? What are the implications if the content were actively seeking out and injecting itself into the web infrastructure (i.e., searc...
