PREMIS는 OAIS의 개념적 프레임워크의 한계를 넘어 보존 실무에 적용할 수 있도록 개발되었지만, 각 메타데이터 요소들을 실제 데이터와 어떻게 연결시킬 것인지에 대한 사례와 지침이 명확하지 않아 디지털 아카이브에서 실제 보존 메타데이터를 설계하거나 구현하는데 어려움이 있다. 이에 본 연구는 다양한 디지털 아카이브의 환경에서 디지털 자원을 관리하고 보존의 목적으로 활용되고 있는 PREMIS 3.0 기반의 보존 메타데이터 실제 사례들을 조사하고 보존 메타데이터 구현 및 설계를 위한 시사점을 도출하고자 하였다. 분석 결과를 토대로 PREMIS의 응용프로파일 지침에 따라 디지털 아카이브의 보존 메타데이터 설계 시 고려할 수 있는 보존 메타데이터 요소들을 제안하였다.
The development of the Preservation Metadata: Implementation Strategies (PREMIS) aims to preserve practices beyond the limits of the Open Archival Information System (OAIS) conceptual framework; however, the examples and guidelines on connecting each metadata element to the actual data are unclear, making the design of preservation metadata in real digital archives difficult. Hence, this study investigates actual PREMIS 3.0-based preservation metadata management cases, preserves digital resources in various digital archive environments, and derives implications for the implementation and design of preservation metadata. Based on the analysis, the study proposes preservation metadata elements that can be considered when designing preservation metadata for digital archives according to PREMIS 3.0 application profile guidelines.
Digital resources are widely used in our modern society. However, we are facing fundamental problems to maintain and preserve digital resources over time. Several standard methods for preserving digital resources have been developed and are in use. It is widely recognized that metadata is one of the most important components for digital archiving and preservation. There are many metadata standards for archiving and preservation of digital resources, where each standard has its own feature in accordance with its primary application. This means that each schema has to be appropriately selected and tailored in accordance with a particular application. And, in some cases, those schemas are combined in a larger frame work and container metadata such as the DCMI application framework and METS. There are many metadata standards for archives of digital resources. We used the following metadata standards in this study for the feature analysis me metadata standards - AGLS Metadata which is defined to improve search of both digital resources and non-digital resources, ISAD(G) which is a commonly used standard for archives, EAD which is well used for digital archives, OAIS which defines a metadata framework for preserving digital objects, and PREMIS which is designed primarily for preservation of digital resources. In addition, we extracted attributes from the decision tree defined for digital preservation process by Digital Preservation Coalition (DPC) and compared the set of attributes with these metadata standards. This paper shows the features of these metadata standards obtained through the feature analysis based on the records lifecycle model. The features are shown in a single frame work which makes it easy to relate the tasks in the lifecycle to metadata elements of these standards. As a result of the detailed analysis of the metadata elements, we clarified the features of the standards from the viewpoint of relationships between the elements and the lifecycle stages. Mapping between metadata schemas is often required in the long-term preservation process because different schemes are used in the records lifecycle. Therefore, it is crucial to build a unified framework to enhance interoperability of these schemes. This study presents a basis for the interoperability of different metadata schemas used in digital archiving and preservation.
