  • In this paper, we introduce a novel Climate & Environment Database System (CEDS). The CEDS is developed by the National Institute of Meteorological Sciences (NIMS) to provide easy and efficient user interfaces and storage management of climate model data, so improves work efficiency. In uploading the data/files, the CEDS provides an option to automatically operate the international standard data conversion (CMORization) and the quality assurance (QA) processes for submission of CMIP6 variable data. This option increases the system performance, removes the user mistakes, and increases the level of reliability as it eliminates user operation for the CMORization and QA processes. The uploaded raw files are saved in a NAS storage and the Cassandra database stores the metadata that will be used for efficient data access and storage management. The Metadata is automatically generated when uploading a file, or by the user inputs. With the Metadata, the CEDS supports effective storage management by categorizing data/files. This effective storage management allows easy and fast data access with a higher level of data reliability when requesting with the simple search words by a novice. Moreover, the CEDS supports parallel and distributed computing for increasing overall system performance and balancing the load. This supports the high level of availability as multiple users can use it at the same time with fast system-response. Additionally, it deduplicates redundant data and reduces storage space.

  • It has lately been recognized that the sharing and exchanging of the research results information is the critical factor to improve the research productivity. So many institutions are planning or developing the information systems which provide the research information services for researcher. But it has very difficulty in integrating the research resources information due to the dispersion and heterogeneity in data sources, and semantic and structural difference in describing data. We propose the semantic web based methodology and conceptual framework for raising the interoperability of metadata about research results information, which will support the integration of the distributed research data for information services in the end. Finally we proposed the conceptual architecture of research information service system which shows the main components, the functional requirements, and the principal and design direction at implementing the system.

  • Geospatial interoperability has been pursued by propagating international standards and OGC standards. The NGIC, GeoConnection and other catalogue services are reviewed with aspect to metadata and search functions. Detailed metadata could be driven to users after finding what they want to have. Criteria for search were not fully overlapped with metadata, as simple and typical searches are prevailing. OGC catalogue service standards were made but catalogue services in Korea have been implemented in their own ways, not fully compliance-tested. Different domain technologies have been developed regardless of geospatial service, the relationship and integration methods between catalogue services and other core technologies are reviewed in the form of a pair table. Other issues in geospatial service were discussed in the level of raising issues.

  • Forest type map is a main forest thematic map which shows forest type, age class, diameter class and density. This map has been used as a base data in various fields such as forest policy decision-making, land suitability assessment and eco map production etc. But the existing map had many kinds of errors and no metadata because there was no standard for digital map production. On this study, we developed standard for digital forest type map production consisting of 33 unit processes including DB schema design, mapping process, quality control and metadata input process. Based on this standard, country-wide digital forest type map can be produced with consistent quality and standard metadata.

  • The purpose of this study is to design textbook metadata as a basic task for building a textbook database. To this end, reading textbooks were defined as a category of textbooks, and a metadata development methodology was established through previous research. In order to ensure that bibliographically essential elements are not omitted, the catalog description elements of institutions that collect, accumulate, and service textbooks such as the National Library of Korea were investigated. The elements of Dublin Core, MODS, and KEM were mapped to derive elements suitable for describing textbooks. Finally, a set of textbook metadata elements consisting of 14 elements in three categories - bibliography, context, and textbook characteristics were presented by adding publication type, genre, and curriculum period elements. The 14 elements are titles, authors, publications, formats, identification sign, languages, locations, subject names, annotation, genres, table of contents, subjects, curriculum period, and curriculum information. In this study, we contributed to this field by discussing how to organize textbook resources with national knowledge resources, and in future studies, we proposed to evaluate usability by applying metadata elements to actual textbooks and revise and supplement them according to the evaluation results.

  • Managing electronic medical record is very difficult, because the currently electronic medical system is not designed standard that is uniform and proper. In this paper, in order to overcome this situation, we propose meta-data for the management of the electronic medical record as a single system. To this end, we first analyzed the research on electronic medical records and related standards. Second, we, on the basis of the analysis result, abstracted electronic medical record and entities related on electronic medical, and we designed an entity-relationship model. And finally, we have to complete the meta-data through the setting attributes in this entity-relationship model. Through this study, it was possible that we can complete metadata highly expressive medical records, and suggest an alternative for problem of current medical records systems.

  • SQL/MDR is a metadata registry query language used to consistently exchange and share the data between distributed metadata registries. It is an extension of the international SQL and is familiar to most database builders and administrators. It provides many advantages such as simplicity of query language, ease of use, an independent description for distributed querying, low cost for adding new systems, simplicity of exchanging mechanism, and so on. The goal of this paper is to evaluate and show its merits quantitatively. To achieve this goal, we define simulation models to compare with an existing approach and then describe the evaluation results. In the quantitative evaluation results, the good points of SQL/MDR can be identified and known.

  • The share of the internet has grown significantly in terms of usage and level of influence. Among the internet media, OhmyNews is considered a alternative media representing Korea's independent internet news, and a typical example displaying characteristics of the internet news. The processing step can be divided as five stage, with recorded information and applicable technical element extractable from each stage. In this thesis paper, we have analyzed domestic and overseas metadata standard examples to devise metadata design plans. Items to be focused when redesigning metadata based on domestic and foreign case studies are as follows: First, user access should be convenient; second, connection with related information should be considered; third, accumulation of production, management, usage, storage, and action history should be considered; and fourth, the design should allow higher utilization of contents. In depth researches over internet media are already being carried out in external academic disciplines including the media information studies, information and communication studies, and communications studies. We expect that it will also be necessary to consider such researches over the internet media for mass media record management research going forward.
