The current challenges associated with the preservation of electroacoustic music in its various forms are inextricably linked to the evolution of digital technologies. This evolution not only affects electroacoustic composition, but also compositions for acoustic instruments created with music notation programs, and perhaps most significantly, recorded music. The InterPARES project (International Research on Permanent Authentic Records in Electronic Systems) was founded in 1998 by an international group of researchers representing universities, national archives, and industry representatives from fifteen countries. The stated aim of the project is to ?formulate principles and criteria for the development of international, national and organizational policies, strategies, and standards for the long-term preservation of authentic electronic records.? While the project is multi-disciplinary in its approach, the field of electroacoustic music has been identified as one in which the issues of media obsolescence and intellectual property are particular relevant, and as such, has been made the focus of the Canadian research team. One goal of the research is the population of a digital records typology which will address a variety of methods of music representation, both technically and philosophically. It is hypothesized that appropriate strategies will entail modeling digital music documents as part of an functional system described by the theory of diplomatics. By conducting several case studies of both public and private musical organizations, the InterPARES project hopes to develop strategies for the long-term maintenance of digital musical records, and to adapt these strategies for use in other related disciplines.
