  • The description of preserved resources is one of the requirements in digital preservation. The description is generally created in the format of metadata records, and those records are combined to generate information packages to support the process of digital preservation. However, current strategies or models of digital preservation may not generate information packages in efficient ways. To overcome these problems, this research proposed an internal structure of information packages in digital preservation. In order to construct the internal structure, this research analyzed existing metadata standards and cataloging rules such as Dublin Core, MARC, and FRBR to extract the core elements of resource description. The extracted elements were categorized according to their semantics and functions, which resulted in three categories of core elements. These categories and core elements were manifested by using RDF syntax in order to be substantially applied to combine metadata records in digital preservation. Although the internal structure is not intended to create metadata records, it is expected to provide an alternative approach to enable combining existing metadata records in the context of digital preservation in a more flexible way.

  • This research designed and proposed metadata elements for the long-term preservation of digital research outcomes collected and managed in electronic file form. Metadata structure of both domestic and foreign agencies that manage research outcomes and CERIF and PREMIS-preserved preservation metadata were referred to design the metadata elements. The metadata design was divided into research information, bibliographic information and archival information. Research information is divided into project, name and institution, and composed of eight top-level elements and 29 sub-level elements. Bibliographic information is composed of 13 top-level elements as the source of research reports. Archival information is composed of 18 top-level elements and 62 sub-level elements as the elements for context, structure, contents and management process of the electronic records.

  • The following research questions are examined in this paper. What hinders quality metadata generation and metadata interoperability? What kind of semantic representation technique can be utilized in order to enhance metadata quality and semantic interoperability? This paper suggests a way of handling semantic ambiguity for metadata generation. The conceptual graph is utilized to disambiguate semantic ambiguities caused by isolation of a metadata element and its corresponding definition from the relevant context. The mechanism introduced in this paper has the potential to alleviate issues dealing with inconsistent metadata application and interoperability across digital collections.

  • Metadata is data about data that is used to mange data itself. As applications based on DBMS are increased, it is suggested that metadata model and metadata interchange model to manage metadata in DBMS. but metadata which is in the form of XML (eXtensible Markup Language) document is generally stored into RDBMS. Therefore In this paper, as for the method to store metadata of RDBMS into OODBMS, we design metadata model, metadata interchange model and implement new repository system. The metadata of RDBMS is translated into in the form of XML Document and integrated into XML Data Server on OODBMS, eXcelon and executes retrieval metadata information about RDBMS by XQL(XML Query Language). So It is possible to searchm edit a metadata. The metadata of XML documents stored in eXcelon is easily made to be printed in web browser by applying a XSL (extensible StyleSheets Language). So we can have a detail information about property of metadata in DBMS.

  • Recently many organizations have attempted to build hypermedia systems to expand their working areas to internet-based virtual work places. It is thus important to manage corporate hypermedia documents effectively. Metadata play a critical role for managing these documents. This paper identifies metadata roles and components to build its schema. Furthermore a meta-information system HyDoMiS(Hyperdocument Meta-information System) is proposed by the use of this metadata schema. HyDoMiS performs three functions; metadata management search and reporting The metadata management function is concerned with workflow document and database. The system is more likely to help implement and maintsain hypermedia information system effectively.

  • OMG's Common Warehouse Metamodel is now a single data warehouse metadata standard. Interchange of metadata between data warehousing tools and metadata repositories made easy and convenient by using CWM. In this paper, we present the origin, importance and architecture of CWM, and offer an application case.

  • This study aims to investigate a framework for linkage of national research performance evaluation and research information service from the perspective of metadata representation and exchange. Based on results of the functional requirements for metadata of national research performance evaluation are derived, this study suggests strategies for the application of international metadata standards. Also, this study presents an method to implement the metadata of research performance evaluation based on OAI-ORE, which is an international standard that can reuse and exchange the research information on web architecture.

  • The 'National Research Data Platform' and the 'Bio Research Data Platform' were recently built and each is actively creating an ecosystem. It is built independently based on other metadata standards, which may cause future interoperability issues. The purpose of this study is to propose a basis for metadata interoperability between the two platforms. To this end, the metadata standards of each platform were analyzed, crosswork targets were selected and mapped, and the suitability of the mapped elements was verified through experts in the bio field. And more appropriate mapping elements were recommended to derive metadata elements for datasets and files. Through this, it was possible to confirm the possibility that the metadata of each platform could be semantically linked and the basis for securing interoperability.

  • It is important to develop standard metadata to give more plentiful information about the forest cover type map and to promote distribution by National Geographic Information Clearinghouse. In this study metadata for the forest cover type map was designed based on TTAS.IS-19115 and it consisted of 10 packages and 50 elements. Also metadata editor was developed to implement metadata with standard schema and metadata viewer to service more user friendly interface. This work was about the first standard metadata for forest GIS data. So it would be a useful reference to develop metadata for other digital map concerning forest.

  • In this paper, we introduce a computing resource standard metadata schema design plan for registering, retrieving, and managing computing resources used for research data analysis and utilization in the Korea Research Data Commons(KRDC). KRDC is a joint utilization system of research data and computing resources to maximize the sharing and utilization of research data. Computing resources refer to all resources in the computing environment, such as analysis infrastructure and analysis software, necessary to analyze and utilize research data used in the entire research process. The standard metadata schema for KRDC computing resource management is designed by considering common attributes for computing resource management and other attributes according to each computing resource feature. The standard metadata schema for computing resource management consists of a computing resource metadata schema and a computing resource provider metadata schema. In addition, the metadata schema of computing resources and providers was designed as a service schema and a system schema group according to their characteristics. The standard metadata schema designed in this paper is used for computing resource registration, retrieval, management, and workflow services for computing resource providers and computing resource users through the KRDC web service, and is designed in a scalable form for various computing resource links.
