from the site:

Making digital documents available long-term is one of the still unsolved problems of our information society. With the increasing number of electronic publications, it is becoming critical that we reliably archive them. In the course of technological development, new digital file formats which are dependent on specific hardware and operating systems are continually being developed and used. Thus, older data are often not usable with current hardware and software. The kopal project is dedicated to finding a solution to this problem in the form of a cooperatively developed and operated long-term archive for digital data.

INTRODUCTION
The Technical Evaluation of Open Source Repositories report was
commissioned as part of the Open Access Repositories in New Zealand (OARINZ) project. OARINZ is being undertaken by a collaboration of Tertiary Institutions lead by the Christchurch Polytechnic Institute of Technology.

The project targets the three key recommendations from the National Library’s (2005) Institutional Repositories for the research sector report:

1. Establishment of a national network of Institutional Repositories
2. Support for individual institutional initiatives
3. Adoption of a “common road map”
   

Underpinning these objectives is the need to select best-of-breed Open Source Repository system/s for further enhancement and large-scale deployment across New Zealand.
