Design and Implementation of Open Source Based Digital Preservation Experimental Platform (THDP)

Digital information is instable and easy to be lost. With the rapid development of information technology, the hardware and software used to read digital data become obsolescent soon, while a lot of information in these unreadable data is so valuable for businesses and professions that it is urgent to be preserved for long-term utilization (or "digital preservation"). Since 1980s, there have been a lot of related research projects. However, there is no sound platform to provide an experiment and verification environment for the research of Digital Preservation. By utilizing a series of open source software, this paper proposes a DSpace-based digital preservation experimental platform - THDP, which follows OAIS reference model. This paper also suggests several new functions like Automatic Obsolescence Management System.
