Number 3: Preservation Requirements in a Deposit System
Written by: R.J. van Diessen
The initial DIAS release only provides basic functionality for preserving and rendering the stored digital objects for the long term. One of the primary responsibilities of the LTP Study is to define the functional requirements of the Preservation Subsustem, which is scheduled for development later. This report identifies requirements of the DIAS Preservation Subsystem so as to provide the services and functions for monitoring the technical environment associated with the digital objects stored in DIAS.
The Preservation Subsystem can be summarized by the following three objectives:
- Identifying digital objects that are in danger of becoming inaccessible because of changes in technology.
- Implementing the activities associated with technical preservation.
- Supplying the requisite technical metadata in order to generate/validate the environments needed during digital object delivery.
