In the electronic records environment, along with discussions on ways to digitize analog records, it is important to prepare preservation strategies for each type of records produced and received electronically. In the same context, there is a need for discussion on applying a preservation format selection system with the goal of long-term preservation of data sets and audio-visual type electronic records other than document types. Audiovisual records must apply preservation strategies appropriate to the characteristics of each medium, such as images, audio, and video. This study establishes unique standards for selecting a preservation format for audio-visual electronic records through analysis of Significant Properties based on literature review, composed audio-type preservation format suitability evaluation items, and proposed a recommended format based on the results of applying them.

For the long-term preservation of document-type electronic records, the National Archives of Korea has chosen PDF/A-1 as the preservation format named as the document file format, and established it as a public standard. The only option of selecting PDF/A-1 restricts the use of various electronic file formats that can or must be applied to actual works as IT advances and tasks change. Moreover, it is difficult to apply PDF/A-1 to other types of electronic records (administrative information datasets, audiovisual records, web records, etc.). Therefore, it is necessary to diversify the preservation formats of electronic records. We suggest a framework for selecting various preservation formats. Furthermore, we propose common criteria and evaluation methods frequently applied to all electronic records when selecting a preservation format, and introduce a methodology for deriving intrinsic criteria applied to each type of electronic records.

Based on the risk factor evaluation for the file format, this paper defines the procedures for presenting the long-term preservation plan for that format and the technical information registry necessary for building the system. This is a procedure to perform a risk assessment for the format, evaluate the risk, and select a long-term preservation strategy based on the information registered in the registry and information on the external signature and internal signature of the electronic record. We also reviewed the criteria for selecting appropriate long-term preservation strategies in the process and provided the criteria for adopting each detailed strategy of migration and emulation, which are long-term preservation strategies. And we implemented this process as a long-term preservation decision support system. This system can be used to provide guidelines for the maintenance, management, service and long-term preservation of information resources of electronic records in public institutions such as National Archives of Korea and Libraries.

As the use of information has emerged as the core of national competitiveness, major developed countries and the Korean government have realized the importance of data. They have pursued technical research and standard establishment for long-term preservation and continuously strived for systematic management and preservation of data. However, although various types of data are specified for the purpose of record management in the law, there is no specific method on how to collect, manage and preserve them, except standard electronic documents. In particular, management and preservation of huge datasets from the administrative information system have been strongly demanded above all. Any guidelines for datasets do not have been properly provided. After the framework for selecting preservation format must be prepared, the system can be supplemented and built. The framework considering the characteristics of the dataset should be specified more concretely, and empirical verification of the conversion and restoration for the dataset preservation format derived according to the selection criteria is necessary. Therefore, this study intends to propose a method for long-term preservation through empirical verification of the preservation format after deriving an evaluation the framework for the preservation format selection criteria considering the characteristics of the dataset.

This study acknowledges that prevailing regulation concerning for the long-term preservation of electronic records focus mainly on document types, neglecting the preservation of electronic records from various administrative information systems. With the growing interest in data management in the era of big data, it is imperative to establish clear standards for the long-term preservation of datasets. The choice of preservation format for electronic records is based on the specific standards for each type of electronic record. These standards are formulated according to the significant properties relevant to the electronic record type. This study aims to identify the significant properties of electronic records of each record type, before creating specific preservation format selection criteria for these record types. To achieve this, we reviewed and analyzed R&D studies by the National Archives of Korea and the NARA in the United States. As a result of the research, 9 significant properties were identified for database-type entities, and 7 significant properties were identified for structured data-type entities.

It is defined in the internal standard of the NAK namely a NAK/G8-1:2013(v.1.) such as TIFF, PNG, PDF/A, JPEG 2000 as a Long-Term Preservation Master File for internal Standardization of Paper Archives in the Central Archives of Korea. This study reviewed the possibility that JPEG format could be a standard as a Long-Term Preservation Master File for internal Standardization of Paper Archives in the Central Archives of Korea. I pointed to the unique characteristics of JPEG file format and analysed and compared with TIFF format that is a representative master file. Through this study, I suggested that JPEG format also should be additionally included in the standard, as a master file, because it meets a qualification and functional requirements of master file and can guarantee the authenticity, reliability, integrity and usability. The meaning of this study is that JPEG format, be added to master file standard, can set up a environment that has lots of benefit in the domain of usability, compatibility to user as well as the authenticity, reliability, integrity.

The purpose of this study is to analyze the current state of long-term preservation policy for electronic records in Korea and to present future tasks. Although the current electronic record long-term preservation policy is not clearly codified, it can be said to consist of technical elements such as digital signature, hash, preservation format, and long-term preservation package. Each technological element was considered in order, and the limitations of the current policy and technology in the changing digital environment were analyzed and alternatives were presented.

Appropriate strategies are needed to ensure long-term preservation of various types of electronic records. For proper preservation of electronic records, it is necessary of decision-making processes for risk assessment, notification and implementation of conservation measures. To do this, the task of assessing various risk factors that impede the long-term preservation and utilization of electronic records should be done first. In this study, since electronic records are mostly stored in file form, risk assessment for electronic records of file type is performed. The risk factors required for the risk assessment of the file format are derived, and the algorithms are developed to devise a calculation method of the weighting factor and the risk factor index for evaluating the risk based on the proposed risk factors. In addition, the proposed methods are applied to the file formats used in Korea and risk assessment is performed and the results are analyzed.

Along with the changing computing environment, the production of public documents is moving to G-Cloud and On-nara System, which are re-engineered on G-Cloud. In this process, it is predicted that the Open Document Format (ODF) will replace the proprietary document format, HWP, and will become widely used in the near future. To preserve digital records produced in ODF, this study reviewed the current long-term preservation strategies and identified considerations for new formats. For ODF source files, it is suggested to eliminate the conversion to PDF/A-1 and preserve the documents in the extended ODF with added metadata of records management. Moreover, ODF is presented as an alternative format for preserving proprietary formats. Finally, this study reviewed the current long-term preservation format, i.e., NEO, and suggests a zipped BagIt package, which has an ISO 21320 specification.

Unlike paper records, accessing electronic records needs to be supported by specific combination of hardware and software. The electronic records have longer life span than the storage media, hardware, software and the formats that were used for the production of such records. Because the quality of electronic record can become deteriorated as time goes on, we need to have appropriate mechanisms to secure the long-term preservation and access to the digital information at a certain point in the future. Based on this reality, this study proposes the functions and the development method of the format registry, which efficiently supports the preservation strategy such as migration and emulation, collecting and managing technical information elements. These elements consist of the foundation of the long-term preservation of the electronic records.
