SCAPE has released "A Risk Analysis of File Formats for Preservation Planning."
Here's an excerpt:
This paper presents an approach for automatic estimation of preservation risk for file formats. The main contribution of this work is a definition of the risk factors with associated severity level and its automatic computation. Our goal is to apply a solid knowledge base automatically extracted from linked open data repositories as the basis of the risk analysis system for digital preservation. This method is meant to facilitate decision making with regard to preservation of digital content in libraries and archives.
