This paper provides updated information on the Open Archival Information System Interoperability Framework (OAIS-IF) project. The purpose of the OAIS-IF project, developed by the Consultative Committee for Space Data Systems (CCSDS) Data Archive Interoperability (DAI) working group (WG), is to provide interoperability between archive users (producers and consumers of archive data) and the archives, as well as archive-to-archive interoperability. It will first provide background on the CCSDS, the DAI team, and the OAIS Reference Model (RM). It will then introduce the concept of an OAIS-IF; a suite of standards that will support the OAIS and add capabilities for interoperability between users and all archives that comply with the OAIS-IF standards. Interoperability was at the core of the OAIS-IF requirements from the outset. However, (since the presentation at SpaceOps 2018) the team has revamped the data architecture of the OAIS-IF, providing greater modularity, greater capabilities for cross-discipline research, and support for non-OAIS archives. That is the focus of this manuscript. This will benefit space mission archives, other long-term preservation archives, and any other archives that choose to implement OAIS-IF. We also discuss the application of usability to achieve interoperability. The technical concept is based on adapters at both the user location and the archive location that will provide access to all OAIS-IF compliant systems. A user will require only one set of adapters to access archives of many disciplines. And an archive will require only one set of adapters to serve users of many disciplines. There are “generic” and “specific” adapters on both the user side and archive side. The generic adapter provides basic functions which can serve many users and many archives. The specific adapter on the user or archive side performs functions specific to the archive if needed. The result is software reusability for the generic adapters, reducing development burden. This will provide a capability for interoperability between the many users and archives that will eventually subscribe to these standards. Ubiquitous acceptance of the OAIS-IF, if comparable to the acceptance of the original OAIS RM standard, will enhance cross-discipline and long-term accessibility and usability, leading to improved digital preservation capabilities within our archive systems and missions. Missions become more valuable when information is created, captured, and stored in archives for future reference.

摘要

This paper provides updated information on the Open Archival Information System Interoperability Framework (OAIS-IF) project. The purpose of the OAIS-IF project, developed by the Consultative Committee for Space Data Systems (CCSDS) Data Archive Interoperability (DAI) working group (WG), is to provide interoperability between archive users (producers and consumers of archive data) and the archives, as well as archive-to-archive interoperability. It will first provide background on the CCSDS, the DAI team, and the OAIS Reference Model (RM). It will then introduce the concept of an OAIS-IF; a suite of standards that will support the OAIS and add capabilities for interoperability between users and all archives that comply with the OAIS-IF standards. Interoperability was at the core of the OAIS-IF requirements from the outset. However, (since the presentation at SpaceOps 2018) the team has revamped the data architecture of the OAIS-IF, providing greater modularity, greater capabilities for cross-discipline research, and support for non-OAIS archives. That is the focus of this manuscript. This will benefit space mission archives, other long-term preservation archives, and any other archives that choose to implement OAIS-IF. We also discuss the application of usability to achieve interoperability. The technical concept is based on adapters at both the user location and the archive location that will provide access to all OAIS-IF compliant systems. A user will require only one set of adapters to access archives of many disciplines. And an archive will require only one set of adapters to serve users of many disciplines. There are “generic” and “specific” adapters on both the user side and archive side. The generic adapter provides basic functions which can serve many users and many archives. The specific adapter on the user or archive side performs functions specific to the archive if needed. The result is software reusability for the generic adapters, reducing development burden. This will provide a capability for interoperability between the many users and archives that will eventually subscribe to these standards. Ubiquitous acceptance of the OAIS-IF, if comparable to the acceptance of the original OAIS RM standard, will enhance cross-discipline and long-term accessibility and usability, leading to improved digital preservation capabilities within our archive systems and missions.
