  • The major purpose of this study was to design a external metadata which fit domestic demands of the digital maps. For designing a standard external metadata reflecting the current trends of the international organizations on standardization, a prelimenary study was made mainly concentrating on the analysis of the standards of the developed countries. For better assessing domestic needs, all the metadata related material of the National Geography Institute were collected and classified based on the NGI's workflow. The external metadata draft was made considering the results from the analysis of the existing NGI material and the draft was also cited some major cores from the ISO standards. Continuous efforts should be made in the future to update the metadata draft based on the opinions from domestic users and the technical trends of the international organizations on standardization.

  • To solve of complex problems for access and management data stored in the very large spatial database system that need to constructed metadata for the physical and logical elements concerned with spatial and non-spatial data sets. Also, in the underground water management system which managed with spatial and non-spatial elements, need to spatial features metadata system based on feature-based. We, in this paper, proposed metadata model for the feature-based underground water management system using underground water meta-information inputted on the DXF formatted tile-based geological maps. Additional, we modeled metadata level of feature and data set and presented standard specification of underground water metadata.

  • Recently, the publishing community now recognizes the importance of metadata in customers' buying decisions. As a result, they are more interested in effective metadata creation and quality maintenance, as well as standardization of exchanging system in the supply chain. As the library community also investigates the economic effectiveness of creating metadata, they try to find the best model for simplifying metadata creation by using sources close to the original. This study analyzes metadata work flow which had same source but be used in different fields by their own type and standard. It also discusses the same issues about each section and possibility about interoperation. Finally this paper tries to find an effective creation and distribution model of book metadata which can be used in domestic publishing and the library community.

  • Digital Broadcasting serves a variety of broadcasting services for satisfying the requirement of customers. One of main factors for new broadcasting environment is interoperability between providers and consumers. For this interoperability, metadata standards are proposed for the digital broadcasting and TV-Anytime metadata is one of these standards. On the one hand, there are some researches for efficiently managing the broadcasting metadata on Set-Top Box. This paper proposes the metadata management system for efficiently managing the broadcasting metadata based on the STB which is low-cost and low-setting. Our system consists of a storage engine to store the metadata and an XQuery engine to search the stored metadata and uses special index for storing and searching. We expect that our system will keep the interoperability amongst a variety of applications for broadcasting because we adopts the XQuery for searching the metadata and the XQuery is a standard language for searching XML data.

  • The National Science and Technology Standard Classification System is established and operated for the purpose of efficiently managing science and technology related information, manpower, and R&D projects. The revision cycle for the classification system is five years, and 2022 is the first year of the next revision procedures. The main purpose of the next revision is to turn the third level categories into the keywords in the current classification system. It is to solve the problems about not reflecting the latest terms, and the difficulty in linking with the relevant other classifications caused by the rigid structure of the current classification system. In this study, the method was proposed by changing the existing classification system into the term management system as to improve the quality and usability of keywords related with the current third level categories. For this method, SKOS, the international standard terminology management system, and ISO/IEC 11179 standards were offered as basic models. In addition, the related metadata standards used in overseas scientific and technological glossaries were investigated, and compared with the current National Science and Technology Standard Classification System. And then essential metadata elements from the terminology management as point of view was derived. As a result, 11 standard metadata elements that can be immediately modified and applied in the current system were recommended, and five elements that can be applied after the revision of the classification system were offered.

  • Standardization work for the ocean data produced by a variety of national oceanographic research projects was conducted in order to establish a national ocean data sharing system. For this work, we first prepared standard proposals for the national research ocean data by reviewing and analyzing of existing international and domestic ocean-data standards. The proposed standards were reviewed and revised by experts in the field of oceanography and academic societies for documentation. The 125-page technical report on the standards of 25 data items was prepared as an output of this research work, which is available free of charge for the public and interested parties. This paper explains the proposed standards of metadata and codes regarding the common properties of all the oceanographic data items. Especially, the standards for the metadata, codes and data formats of 4 physical data items were described in detail. In order to be adopted as the national standards for ocean data, however, the standards suggested here require further development and/or modification based on additional reviews of and ample feedbacks from the relevant academic and technical communities.

  • Earthquakes and volcanic information can vary in type and extent, from raw data to processed data. In order to be able to analyzed and modeled, information needs to be opened in any formats and provided with metadata from the Korea Meteorological Agency and related data production organizations. We propose the metadata and data registry related to volcanic disasters in a form that can be used in conjunction with the Korea Meteorological Administration system that manages earthquake and volcanic data in Korea. The standard registry refers to a virtual system that checks the standards developed for over 20 years in the field of geographic information and receives information registration to grasp the location of geographical features. It is not only data from natural disasters such as earthquakes and volcanoes, but also national environmental survey results, and the cooperation system with other organizations dealing with national land information is also important, so a registry that creates and operates standards is necessary. Therefore, creating and operating the standard registry is necessary and expected to contribute to academic openness and data-driven policy.

  • Inundation Maps are used to predict potential areas of flooding through the signs of past flooding and flood inundation analysis for flooding expected in the future, and this has led to the development of various forms of disaster-related services by governments. However, each institution has its own individual scenarios for making maps for spatial expression. Therefore, the type of spatial information is not standardized and has many forms and structures. In this study, we attempted to design the metadata that would allow Inundation Map information to be shared and used in various fields. The international standard, ISO 19115, and the domestic standards, KS X ISO 19115, TTAS.IS - 19115 and TTAS.KO - 10.0139/R1 of TTA, were used in the design to derive an appropriate standard for comparative analysis by dividing into maintenance, constraints, metadata, spatial reference system, identification, and distribution. It is expected that inundation maps will be easier to utilize and distribute among institutions and private companies by systematically collecting and managing them through the metadata design based vector space information standard developed in this study.
