“…From this theoretical foundation, concrete metrics began to be developed for digital preservation activities (Beagrie et al, 2002;Ambacher et al, 2007), culminating in the Audit and Certification of Trusted Digital Repositories, which was codified as an international standard in 2012 (ISO 16363, 2012). Responding to and complementing this standard, library literature has outlined strategies for drafting digital preservation plans and policies (Strodl, et al, 2007;Bishoff, 2010;Mannheimer, et al, 2014); developing repositories for digital preservation (Cramer and Kott, 2010;Elstrøm and Junge, 2014); examining library digital preservation practices (Oehlerts and Liu, 2013); establishing and implementing preservation metadata (Lavoie and Gartner, 2013), and building and evaluating preservationaware digital storage systems (Baker, et al, 2006;Rosenthal, 2010;Han, 2015). Large-scale education and advocacy efforts have also emerged in the library community, including the Library-of-Congress-led National Digital Information Infrastructure and Preservation Program 1 in the United States and the Open Preservation Foundation (formerly Planets Project) in Europe.…”
