Archives are an essential part of our societal memory. The use of Information Technology (IT) in archival context has pointed out the need of preserving digital information. There is a need of methods and techniques for preservation activities and the development of supporting tools. Archival Information Systems are a special kind of information systems. The development of Archival Information Systems has to be non-ad hoc implementation based upon archival and long-term preservation thinking. The paper A Foundation for Archival Information Systems Development (Quisbert, Hagerfors, 2006) proposes a thinking framework based upon the Records Continuum Model and the OAIS Reference Model. In this paper, a Computational Independent Model for an Archive Information System (AIS), based upon mentioned framework, is proposed. The Model Driven Architecture, proposed by the Object Management Group, has been chosen as an example for the creation of this model.The Centre for Long-term Digital Preservation (CLDP) connected to the Luleå University of Technology (LTU) in Sweden, is an R&D division working with digital preservation issues. The intention of the proposed model is to be the fundament for developing a prototype for an AIS, at this centre. Empirical contribution to this model has been given by archivists, by experimental student projects at the LTU, and systems developers at the CLDP. Later, a complete software implementation base upon the proposed framework should support long-term preservation of digital information by reflecting important characteristics of the Continuum Model and the OAIS Reference Model.
