Abstract: Communicating with the Future: Challenges and Solutions in Digital Preservation Increasing amounts of information are being created and maintained in digital form. This includes objects from virtually every discipline and type, such as e.g. office documents and email communication, government records, simulations, scientific datasets, photos and videos, computer games and digital art, social networks and all kinds of applications in the form of software and hardware. Many of these objects need to be preserved and maintained accessible over long periods of time, be it out of legal requirements, because they form the basis of business models, because they constitute valuable cultural heritage, because we need them as evidence and proof of scientific experiments, or because of personal reasons and value. Yet, contrary to conventional objects, digital one are very fragile. While we can open and maybe be able to read a manuscript that is several hundred years old, trying to access a spreadsheet from the early eighties may turn out to be almost impossible. Digital objects may be stored on media for which no reading devices are available anymore. Even if we can read the bits from the data carrier, digital objects need specific programs to open and render them. These, in turn, need specific libraries and a suitable operating system, which in turn only runs on specific hardware with drivers for specific devices. If any of these is not available, a digital object is nothing but a series of 0's and 1's. Digital Preservation aims at maintaining digital objects accessible in an authentic form over long periods of time. This talk will review some of the core challenges in this endeavour and show potential solutions. It will touch on the OAIS reference model, an ISO standard for an open archival information system, and focus particularly on issues of preservation planning to achieve a trustable digital archive, pointing at numerous open research issues. Bio: Andreas Rauber is Associate Professor at the Department of Software Technology and Interactive Systems (ifs) at the Vienna University of Technology (TU-Wien). He furthermore is president of AARIT, the Austrian Association for Research in IT. He received his MSc and PhD in Computer Science from the Vienna University of Technology in 1997 and 2000, respectively. In 2001 he joined the National Research Council of Italy (CNR) in Pisa as an ERCIM Research Fellow, followed by an ERCIM Research position at the French National Institute for Research in Computer Science and Control (INRIA), at Rocquencourt, France, in 2002. From 2004-2008 he was also head of the iSpaces research group at the eCommerce Competence Center (ec3). In 1998 he received the ÖGAI Award of the Austrian Society for Artificial Intelligence (ÖGAI), and the Cor-Baayen Award of the European Research Consortium for Informatics and Mathematics (ERCIM) in 2002. He is a member of the Association for Computing Machinery (ACM), The Institute of Electrical and Electronics Engineers (IEEE), the Austrian Society for Artificial Intelligence (ÖGAI). He also serves on the board of the IEEE Technical Committee on Digital Libraries (TCDL). He is actively involved in several research projects in the field of Digital Libraries, focusing on the organization and exploration of large information spaces, as well as Web archiving and digital preservation.
