The AIMS Project has released AIMS Born-Digital Collections: An Inter-Institutional Model for Stewardship.
Here's an excerpt:
The AIMS project evolved around a common need among the project partners — and most libraries and archives — to identify a methodology or continuous framework for stewarding born-digital archival materials. These materials have been slowly accumulating in archival backlogs for years but are rapidly growing as more contemporary collections are accessioned. . . .
Into this climate, the AIMS partners proposed an inter-institutional framework for stewarding born-digital content. The AIMS partners realized that they could not solve all problems associated with born-digital materials but decided to focus their attention on professional practice defined by archival principles and by the current state of collections at the partner institutions.
In developing the AIMS Framework, the project would apply a practitioner-based research approach by developing a model based on real case studies of collections at each institution. Applying our theories would confirm or challenge the initial framework which could then be used as a model around which to build individual workflows and processes within each partner's organization.
