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.

At present Content Management Systems (CMS) with various and diverse web contents have been in wide applications. But, for CMS of each enterprise has its own metadata which is very different from others, it causes the serious problem of web contents repetition. Also, it's a difficult technology to support protecting copyright of web contents which are in separated CMSs. Therefore, in this paper, we solved the problem of contents repetition through metadata integration between mutually heterogeneous CMSs. We also propose the technology of web contents authentication code for avoiding contents repetition and applying digital rights protection by supporting safe ship in vast quantity of contents.

The study designs and implements a KORMARC/EAD integrated system for the Myongji Digital Library Collections. The purpose of this paper is to design the metadata to Myongji Korean History Collections to provide digital information of high quality to clients, and to develop and implement a model for managing digital library collections. In order to test the model and the quality of the derived metadata, we built a metadata management system, which is connected to the existing KORMARC system. The system consists of two modules- a retrieval and an input module. While in the retrieve mode, one can retrieve KORMARC records of books and archival items, with links to modified EAD files for archival items or to image files for books, in the input mode, one can type two types of data such as a catalog data and an inventory data. Finally, we evaluated the proposed system via mail questionnaires, and propose three suggestions to make this system a much more comprehensive and effective system.

The purpose of this paper is to introduce and discuss a newly-constructed metadata database system that facilitates the retrieval of faculty syllabi available on the Internet. This gateway system aims to provide users with one-stop access to syllabi posted by the faculty of the institutes of post-secondary education from all around the world. Several elements of the Dublin Core (DC) and other supplementary elements were used for cataloging the syllabi. The conceptual schema of all the selected elements of the syllabi was developed following the entity-relationship model. The metadata of the syllabi was then stored in a relational database system. Various searching and browsing interfaces were implemented to facilitate effective retrieval. The prototype, named as Gateway to Faculty Syllabi (GFS), is available at http:/Ais.skku.ac.kr/gfs/.

Metadata standardization of resources, having a heterogeneous metadata structure for each presidential archive and presidential library and museum is preferentially required for utilizing and sharing presidential records. An integrated operation model of metadata to manage various types of presidential records is then needed. The purpose of this study is to create a design principle of integrated metadata, and to suggest relationships and attributes of metadata, needed for developing integrated metadata operation system on presidential records. The design principle includes "creation of relationship among presidential records", "design of each entity, applicable multiple entity data model", "design to describe various types of presidential records", "design to reflect lifelong management on records of holding institutes", and "designing hybrid metadata for long term preservation". Metadata element set consists of elements for common attributes with all types of presidential records for a unique attribute for a specific presidential record and for reference information among different records related to the production of presidential records.

This paper suggests metadata as an effective search tool suitable for moving images on the web. Dublin Core, a leading metagata sceme of web resources, and MPEG-7, a coming international standard developed by MPEG, are used to construct a hybrid metadata scheme. RDF is selected as a framework for a matadata description and Moving Image Core was developed as a RDF schema. Finally, RDF/XML encoded metadata of moving images are retrieved throuth web-based database system using ASP technology.

지형공간 정보 시스템의 상호운용성 및 메타데이터에 관한 관련 연구의 대부분은 모델의 개발과 표준 사양의 정의, 데이터 포맷의 표준화 등에 초점이 맞추어져 있으며 시스템 상호 운용성을 고려한 메타데이터 관리 시스템의 구체적인 설계와 구현에 대한 연구는 상대적으로 아직적은 비중을 차지하고 있다. 이 논문에서는 지금까지의 지형공간정보에 대한 메타데이터와 관련된 기술 표준화 동향을 수용하며 이기종 분산환경에서 지형공간정보의 상호운용성을 지원하기 위한 메타데이터 관리 시스템을 통합메타데이터 저장소의 형태로 구현하기 위한 방법을 제시한다. 또한 설계된 메타데이터 관리자의 시스템 구성요소들의 기능 명세를 세부적으로 정의하여 상호운용성을 제공하는 메타데이터의 관리방법으로써의 통합메타데이터저장소 시스템과 관리자의 기능을 제시하도록 한다.

Data warehouse (DW) is important for analytical processing. Metadata is a key to its architecture. This paper proposes an architecture that consists of seven components. To illustrate data warehouse environment (DWE), this Paper proposes taxonomies having four flows. on the basis or the taxonomies and metadata, this paper proposes a methodology for building the data warehouse and metadata simultaneously. This integrated development methodology (IDM) consists of seven phases: (i) preparatory phase, (ii) requirement analysis phase, (iii) data warehouse development phase, (iv) operational data store development phase, (v) data mart development phase, (vi) metastore development phase, and (vii) maintenance phase. A metastore system is Proposed to help develop metadata interactively. An illustrative example is investigated to demonstrate the usefulness of IDM.

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.
