The title of my presentation will be “Long-term Preservation of Digital Data: Current Issues and Challenges”.

Nowadays more and more information is stored in digital format. With the development of computer science and its related technologies, new hardware and software emerge every day. At the same time, old hardware and software become obsolete and the data on those computers become inaccessible. Therefore, the development of environments to preserve digital data for a long-term (such as 50 years) has become a critical issue. To this end, from the 1980’s, people have begun investigating the issue in order to create good approaches and methodologies for the long-term preservation of digital data. Recently, ISO has announced Open Archival Information System (OAIS) Reference Model as its standard ISO 14721, which provides a common conceptual framework for the environment, functional components, and information objects of a long-term preservation system. But, there are still many challenges in the data long-term preservation field, including storing vast heterogeneous digital data, designing affordable and reliable tools, and constructing full-fledged preservation architectures.

My presentation will focus the following issues:
