The objective of digital preservation is to ensure that digital information survives in usable form for as long as it is wanted That is to ensure long-term access to digitally stored information. The preservation of digital objects involves a variety of challenges, including policy questions, institutional roles, legal and rights issues, metadata, and technical strategies. In this paper, I introduce the definition of digital object life-cycle of digital object and related archiving workflow which are basic concepts of digital archiving. Also I focus on the aspects of current techniques used in digital information preservation including technology preservation, emulation, refreshing, migration, encapsulation.

University libraries have developed digital information resources for digital services and have tried to preserve valuable digital information. Because digital preservation raises challenges of a fundamentally different nature which we added to the problems to preserving traditional format materials, it is necessary that preserving digital resources must be discussed and researched actively. This study conducts risk management for exploring preserving technologies and assessing tools. It is found that most university libraries have used format conversion frequently and do not use the emulation technology. It is also found that medium refreshing has the lowest risk probability and isk impact, but information migration and emulation technology have the highest in the risk probability and in the risk impact individually and the absence of full-time professional staff causes high risk.

The construction of preservation metadata is a prerequisite for the preservation of digital information. In the current approaches to digital archiving, however, there is no metadata structure optimized to describe preserved digital objects. This research proposed metadata packages that can support the description of digital objects from the perspective of the core processes of digital archiving. The proposed metadata packages consist of 4 wrapper elements and 25 sub-elements. They can provide detailed descriptions required to preserve digital objects in accordance with the core processes of digital archiving. Therefore, the proposed metadata package can be applied to digital archiving as a better approach to the description of digital objects compared to the approaches to information package.

The purpose of this study is to investigate the transformation of archival appraisal theories in the digital environment. It is clear that the archival appraisal in the degital information technology era, characterized by the mass production of data type records on the information infrastructure will be fundamentally different from before. As the meaning of selecting in appraisal will be reduced, the existing archival appraisal theories need to be reviewed again. We can expect the decentralization of appraising centered on the national archives, considering the social proliferation of digital information technology. Meanwhile, expertise in archival appraisal will also be changed to a new professional acceptance model for digital technology. Digital technology will give us opportunities for a paradigm shift that may be difficult to understand with existing thinking of archival appraisal.

현재의 고도 디지털 정보화 사회에서는 많은 자료들이 디지털로 생산, 관리, 이용, 보존되고 있으며 이들의 안전한 장기보존은 역사의 연속성 측면에서 매우 중요한 문제이다. 공공기관, 민간기업 등 대규모 조직에서는 조직의 연속성을 보장하기 위해 이런 디지털자료의 보관을 위해 많은 노력을 기울이고 있으나 개인의 디지털 자료는 영속성 있게 보관하기가 매우 어렵다. 이 논문에서는 개인이 소유한 디지털 유산도 안전하게 장기보존될 수 있어야 한다는 필요성을 제시하고 이를 위해 필요한 정책적, 기술적 방안들에 대해 검토해 보고자 한다.

Digital preservation becomes, nowadays, one of the important business process in the academic libraries. This study is to investigate the librarians' perception on digital preservation requirements and to analyze the business practices of the digital preservation and digital preservation level in the 102 academic libraries. In results, it is found that the digital preservation specialists in academic libraries have almost same perception on basic policies and direction. Also, the study finds that the important function of digital preservation is to secure authenticity and integrity; policy and expertise are the most important key components for digital preservation; the most frequently reported barriers to preservation are the lack of willingness and funding problems; most librarians want to learn and train how to establish preservation planning and policy. In general, most librarian think that the level of digital preservation in the academic libraries is insufficiency. Therefore the academic libraries should establish the relevant digital preservation policy and business workflows and to develop capacity of digital preservation.

In this study, description elements of National Archives of Korea(NAK) and National Assembly Archives(NAA) were collected and analysed based on PDI(Preservation Description Information) of OAIS Reference Model(ISO 14721). As for NAK, records management guideline published in 2009 and metadata standards published in 2007 were analysed. As for NAA, Records management manual published in 2009 and metadata applied in national assembly records management system were analysed with group interviews. As a result, improved metadata details and sub-elements were suggested based on OAIS PDI concepts and Calanag's and Russell's research.

Assuring that the integrity of digital contents is reliably maintained is an important component of long-term digital preservation. The purpose of this study was to examine and analysis the best practices of digital preservation policy and provide the basis theory for establishing a preservation policy for maintaining the integrity of digital contents. In order to achieve the purpose of the study, we examined the digital archiving practices for maintaining the integrity of digital contents. Especially, we focused on the storage media and file formats, the media and format conversion, disaster prevention and recovery, management and handling, inspection and monitoring, and security policies.

Information modeling that is broadly applied in digital archiving process privides conceptual process that can be used to guide the creation of descriptions for the objects of preservation. However, it has faced with the limitations on substantially applying to the creation of preservation metadata records. This research proposes the concept of Resource Cluster in order to address these problems and efficiently describe the objects of preservation during digital archiving process. It also constructed Preservation Description Framework (PDF) based on RDF in order to substantially manifest preservation descriptions. This framework combines the structure of OAIS Reference Model and Functional Requirements for Bibliographic Records (FRBR) and can be an alternative approach to the creation of preservation metadata in more efficient and effective ways.

This study endeavors to delineate the essential components of digital preservation policies requisite for data repositories. Drawing from an examination of digital preservation policies from data repositories accredited by CoreTrustSeal in 2023, this study unveils the pivotal components intrinsic to a digital preservation policy framework, subsequently elucidating the content each component encompasses. The proffered framework is anticipated to serve as a foundational reference for institutions aiming to craft their digital preservation policies, transcending the confines of those solely pursuing CoreTrustSeal certification, to encompass both domestic and international institutions irrespective of their intent to seek CoreTrustSeal certification.
