The new environment for records managements requires the revolutionary transition from paper-record management to electric-record management. Capturing contents, contexts, and structure informations of the electric records to preserve the evidentiality, authenticity, and reliability is the outstanding issue. The recordkeeping metadata has been placed at the center of the current issue. This study focused on the establishment of the structures of recordkeeping metadata for current and semi-current stages in the life cycle of records. The reason concentrated on current and semi-current stages is that the authenticity of the record is concerned as the evidence of the business processes. Current and semi-current stages are where the records is able to be produced, captured and managed in the business context. The metadata can be collected and preserved with authenticity. This study explained the relations between entities concerned with producing records and proposed the metadata elements by establishing data model.

Metadata is data that explains attributes and features to the data as structured data. Among them, video metadata refers to data extracted from information constituting the video for accurate content-based search. Recently, as the number of users using video content increases, the number of OTT providers is also increasing, and the role of metadata is becoming more important for OTT providers to recommend a large amount of video content to individual users or to search appropriately. In this paper, a study was conducted on a method of automatically extracting metadata for mood attributes through sound effects of images. In order to classify the sound effect of the video and generate metadata about the attributes of the mood, I would like to propose a method of establishing a terminology dictionary for the mood and extracting information through supervised learning.

A great number of geological research data have been produced by individually conducted researchers and then personally stored in domestic universities and research institutes. However, it is difficult to share data with other researchers owing to low and limited accessibility. The purpose of this study is to systematically establish metadata for inaccessible data, to manage them collectively and to provide opportunities for utilizing the data to those who require efficient research methods. Approximately 1,000 geological specimens (900 rocks and fossils, 100 thin sections) were gathered, along with their metadata such as high-resolution photographs, classification, name, owner, address, and geographical coordinates of the sample site, to establish their features. Additionally, 3D modeling data for 100 rocks and fossils were generated. On the basis of this study, it is possible for researchers to access and share crucial geological data that have a high potential to be lost and have been neglected in restricted spaces; by avoiding the wasted time, energy, and costs caused by repetitive collection of data, researchers may perform effective research and achieve qualified and competitive research results. Moreover, vulnerable and important geological data in the field can be protected from damage caused by indiscriminate, repetitive collection of specimens that have previously been secured. Through the establishment of additional metadata concerning the diversity of rocks, fossils, and thin sections kept at other universities and research institutes, much more data can be recognized, leading to advanced research results. Furthermore, specialized comparison and analysis of basic mineralogy and petrology knowledge are anticipated, based on the use of the metadata.

In this research, we intended to discover all types of information related to international research cooperation, collect information by each type, and build a database. To this end, we initially developed metadata, discussed with metadata experts to develop metadata in the primary phase, and conducted a survey on the experts related to international research cooperation. Furthermore, we collected and entered data in the meta field for each type of information source, and verified the meta field through processes such as the existence of actual data for each meta field, among others. The types of database designed in this research are the international research cooperation information source database, international research cooperation project database, international research cooperation expert database, international research cooperation institution database, international organization database, and other database, and as a result of validating of the field by entering the data by conducting the survey, the survey results and the data entry rate by field demonstrated such a high rate of consistency. However, only the international organization data field was confirmed to have approximately 25% of the field having the data entry rate of less than 10% despite the high rate of significance rated by the users.

Nowadays, the demand of the output analyzed from the grid data have been sharply increased as the remote sensing technologies and GIS related industry have been developed. Therefore, a metadata access system which fits the requirements of the users should be developed for better managing and utilizing gridded data. In this background, this study defined a common application schema through the analysis of the metadata built by numerous institutes based on the draft metadata standards. The draft metadata standards has been proposed from the study supported by ETRI at 2003 which mainly concentrated on establishing the standards of distributing metadata for the grid data. Also, XML based integrated system was developed to access metadata maintained by SaTReC as well as SIMC to facilitate more convenient data access for the grid data users. The results of the pilot system developed from this study can be expected to contribute to build more efficient and enlarged integrated access system of metadata for grid data.

NGIS projects have been widely proceeded by the central and municipal governments, and the higher cost for proceeding the NGIS projects emphasizes the importance of the data sharing among related agencies. For supporting data sharing, effective data generation, and management. 'THE GUIDELINE FOR MANAGING AND DOCUMENTING GEOGRAPHIC INFORMATION CATALOGUES' has been established and enforced since the year 2002. Although metadata for distributing geographic information through the NGIS distribution network has already been installed, this needs to be complimented to maximize the data utilization. Based on such requirements, a draft standard of the national metadata which is compliant with the ISO 19115 has been proposed from this study. All components of the metadata for distributing geographic information have been included and related metadata items for the management purpose have been derived from domestic and foreign studies. Based on this, draft national metadata standards comprised of 13 sections have been made. The metadata standards from this study could contribute to building basic standards to access and to utilize geographic information in various application field. This would also be fundamental base for activating GIS in public and private sectors.

In this paper, we introduce a big data platform and a metadata management technique for fishery science R & D information. The big data platform collects and integrates various types of fisheries science R & D information and suggests how to build it in the form of a data lake. In addition to existing data collected and accumulated in the field of fisheries science, we also propose to build a big data platform that supports diverse analysis by collecting unstructured big data such as satellite image data, research reports, and research data. Next, by collecting and managing metadata during data extraction, preprocessing and storage, systematic management of fisheries science big data is possible. By establishing metadata in a standard form along with the construction of a big data platform, it is meaningful to suggest a systematic and continuous big data management method throughout the data lifecycle such as data collection, storage, utilization and distribution.

This study aims at designing standard metadata that can be incorporated for advanced utilization of damage prediction maps, and thereby constructing the standard meta-information management prototype system on the basis of the proposed design. Based on the ISO/TC 211 19115 international standard, which is considered as the most widely used standard (as per the results of a domestic and foreign metadata standard survey), the designing process for the standard metadata was established and the metadata was categorized into nine classes. Additionally, based on the output of the standard metadata design process, a standard meta-information management prototype system, capable of checking and downloading meta-property information, was constructed using the JAVASCRIPT language. By incorporating the obtained results, it is possible to maintain the quality of the constructed damage prediction map by establishing a standardized damage prediction map database. Furthermore, disaster response can be actuated through the provision and management of data for effective operation of the proposed damage prediction system.
