Charles Beagrie has released Keeping Research Data Safe 2: The Identification of Long-lived Digital Datasets for the Purposes of Cost Analysis: Project Plan.
Here's an excerpt from the project home page:
The Keeping Research Data Safe 2 project commenced on 31 March 2009 and will complete in December 2009. The project will identify and analyse sources of long-lived data and develop longitudinal data on associated preservation costs and benefits. We believe these outcomes will be critical to developing preservation costing tools and cost benefit analyses for justifying and sustaining major investments in repositories and data curation.
