A New Technical Approach for Preservation of Your Mission Data

摘要

The Open Archival Information System (OAIS) Reference Model is a standard from CCSDS that has achieved broad adoption, driving digital preservation processes in archives around the world. The OAIS Interoperability Framework (OAIS-IF) is a new initiative from the same CCSDS group that promises to add system interoperability to the OAIS processes. This paper describes the technical direction of OAIS-IF and the innovative usage of model-based engineering in developing the standard. The general problem statement for digital preservation is that as technology and software evolve, historic data sets become inaccessible unless the rigor of the OAIS reference model is used in the preservation process. When the OAIS-IF is as widely accepted as the OAIS Reference Model, then it will enhance the integrity of the digital preservation process as well as improving access to archives and enabling cross-discipline research resulting from the broader access. The more specific problem statement for spaceflight missions is that space agencies pay lip service to preservation of science data, but most do not preserve the "lower priority" engineering data and program/project data that would be valuable to future mission planners. This problem is discussed further in the paper, and an invitation is issued to the IAC audience to join the OAIS-IF development effort to ensure that the Interoperability Framework meets the needs of their missions.
