Introduction & Motivation
The Reference Model for an Open Archival Information System (OAIS) is an influential standard in the digital preservation domain. It contains an information model, which lays out some basic ideas about digital information, how it is encoded, interpreted and packaged. It also contains a functional model, which lays out the main functional components that should be present in a digital preservation system.
The CASPAR Project is currently designing and implementing software components for a distributed infrastructure to support digital preservation. The starting point for the design of these components is the OAIS reference model, and in particular, the OAIS information model.
This note captures some initial thoughts on the OAIS information model, working towards answers to the following questions:
- Does the OAIS Information Model make sense?
- Can it be used as the basis for designing software components, within a UML model-driven software engineering process?
