  • The Industrial Metadata Registry(IMR) for standardizing industrial information metadata was implemented and four drafts of metadata sets were developed based on the ISO/IEC 11179. The IMR consists of four individual metadata registries characterized by subject category. Accordingly, the system includes the integrated administration module, and the divisions administration module. The users of the system are divided into committee members and general users. The system has been developed with Oracle 9i and Java JSP over Linux operating system. The system will support the procedure for data sharing and exchanging among users and organizations and improve the availability and manageability of data and provide the standardization of data across the industry.

  • To build the consistency among different metadata systems and to increase the interoperability of that systems even among different domains, naming rules and glossaries for the data elements are necessary. This study provides discussion of naming and identification of the data element concept, data element, conceptual domain, value domain, and its meta model. This study also describes example naming conventions based on ontology derived from the combination with object, properties, and representation of data elements. The naming principles and rules described in this study use I-R analysis, DC metadata set, and SHOE 1.0 as an example of the scientific documents. This study would be a guideline to build the naming rules of metadata based on ontology in various domains.

  • This study proposed a method to redesign the search system by extracting the class, property, and code values of value domain from the key elements of the MDR system that conforms to the ISO/IEC 11179 standard. To implement this, an operating system conforming to the standard is required. Therefore, this study targeted the MDR system of the Korea Information and Communication Technology Association. As a result, it was confirmed that the redesigned MDR system can easily search and utilize specific metadata without understanding the conceptual domain, metadata element concept, metadata element, and value domain proposed in the standard.

  • 특정 도메인의 정보시스템간에 정보를 공유하기 위해서, 정보 시스템들은 도메인별로 사용되는 메타데이터를 각기 정의하여 사용하기 때문에 각각의 정보 시스템간의 정보 공유시 메타데이터의 이질성 문제가 발생되지 않는다. 그러나, 메타데이터의 불일치 문제는 이기종 도메인간에 정보를 공유할때 발생된다. 본 논문에서는 메타데이터를 이용하여 구축된 정보시스템 간의 상호운용성을 증진하기 위하여 메타데이터의 의미적 유사성 측정 방법을 제안한다. 이를 위하여 메타데이터 레지스트리(MDR)에 정의되어 있는 메타데이터에 대한 개념 모델을 정의하고. 개념모델의 인스턴스간에 의미유사성을 측정하는 방법을 제안한다. 제안한 방법을 사용한 결과 도메인이 다른 정보시스템간에 점보공유를 위한 의미적으로 유사한 최적의 메타데이터를 선택할 수 있다.

  • I designed the game UCI identification metadata to enable the game industry to provide copyright protection of game content, the efficiency of the management and distribution. This was mapped with existing UCI metadata which is composed of 9 elements that are applied to international standards for interoperability. I redefined 3 elements and added 3 more elements for reflecting the characteristics of the game. So it is composed of 12 elements in total. The result is verified by the general user survey and expert interviews. And I will develope the game UCI identification metadata management system with the results of study to be utilized by game agencies.

  • The information about eBook cannot be added automatically to library catalog because the eBook Service Provider does not provide enough eBook metadata. Therefore, this paper was developed the eBook library's metadata in order to maintain the compatibility and interoperability analyzed the eBook service provider's metadata, KS X 6100 metadata, Dublin Core, MARC, and TEI Header, and extracted common meradata elements from them. We defined these common metadata elements as a core element and added other elements that uniquely describe eBook characteristics as a detailed adn additional elements for eBook metadata.

  • Record management metadata schema should have robust structure to represent not only elements innate in records itself but also management elements for the life cycle of records according to business activities. To realize these requirement, Information model for record domain is needed and also Metadata framework supporting semantic refinement and data element specialization required in record management business or applications are required. This study analyse main principles and characteristics of metadata scheme, and then suggested a novel method to develope schema systematically and effectively. This study propose information model and set of core data elements of records management based on ISO 15489 and 230381, and show how to implement the record management framework.

  • Metadata is well recognized as one of the foundational factors in archiving and long-term preservation of digital resources. There are several metadata standards for records management, archives and preservation, e.g. ISAD(G), EAD, AGRkMs, PREMIS, and OAIS. Consideration is important in selecting appropriate metadata standards in order to design metadata schema that meet the requirements of a particular archival system. Interoperability of metadata with other systems should be considered in schema design. In our previous research, we have presented a feature analysis of metadata standards by identifying the primary resource lifecycle stages where each standard is applied. We have clarified that any single metadata standard cannot cover the whole records lifecycle for archiving and preservation. Through this feature analysis, we analyzed the features of metadata in the whole records lifecycle, and we clarified the relationships between the metadata standards and the stages of the lifecycle. In the previous study, more detailed analysis was left for future study. This paper proposes to analyze the metadata schemas from the viewpoint of tasks performed in the lifecycle. Metadata schemas are primarily defined to describe properties of a resource in accordance with the purposes of description, e.g. finding aids, records management, preservation and so forth. In other words, the metadata standards are resource- and purpose-centric, and the resource lifecycle is not explicitly reflected in the standards. There are no systematic methods for mapping between different metadata standards in accordance with the lifecycle. This paper proposes a method for mapping between metadata standards based on the tasks contained in the resource lifecycle. We first propose a Task Model to clarify tasks applied to resources in each stage of the lifecycle. This model is created as a task-centric model to identify features of metadata standards and to create mappings among elements of those standards. It is important to categorize the elements in order to limit the semantic scope of mapping among elements and decrease the number of combinations of elements for mapping. This paper proposes to use 5W1H (Who, What, Why, When, Where, How) model to categorize the elements. 5W1H categories are generally used for describing events, e.g. news articles. As performing a task on a resource causes an event and metadata elements are used in the event, we consider that the 5W1H categories are adequate to categorize the elements. By using these categories, we determine the features of every element of metadata standards which are AGLS, AGRkMS, PREMIS, EAD, OAIS and an attribute set extracted from DPC decision flow. Then, we perform the element mapping between the standards, and find the relationships between the standards. In this study, we defined a set of terms for each of 5W1H categories, which typically appear in the definition of an element, and used those terms to categorize the elements. For example, if the definition of an element includes the terms such as person and organization that mean a subject which contribute to create, modify a resource the element is categorized into the Who category. A single element can be categorized into one or more 5W1H categories. Thus, we categorized every element of the metadata standards using the 5W1H model, and then, we carried out mapping among the elements in each category. We conclude that the Task Model provides a new viewpoint for metadata schemas and is useful to help us understand the features of metadata standards for records management and archives. The 5W1H model, which is defined based on the Task Model, provides us a core set of categories to semantically classify metadata elements from the viewpoint of an event caused by a task.
