최근 정보의 디지털화가 보편화되면서, 웹상에서 전자자원의 이용을 원하는 이용자들의 증가와 함께 전자자원이 이를 생성한 개인(또는 기업 등)의 소유물(자산), 즉 라이선스라는 개념이 부각되고 있다. 이용자의 전자자원의 접근과 이용은 라이선스 계약 조건 범위 내에서 허용되어야 하므로 전자자원의 라이선스와 관련한 데이터요소들의 개발 및 이를 통한 체계적 관리가 필요하다. 따라서, 본 논문에서는 이와 같이 전자자원의 라이선스 계약을 용이하게 하기위해 전자자원을 효율적으로 관리할 수 있는 전자자원 라이선스 관련 표준 메타데이터를 설정하고, 타 메타데이터와의 교환과 통합을 위한 기본정보를 제공하는 Information Model을 설계하였다.

A need for sharing the R&D information at a national level regardless of the ministry in charge of it is being aroused. However, this information is being managed by different institutes under different ministries without a standard identifier which makes it difficult to manage the information such as to look up duplicate projects. A URN-based identifier is required for the integrated management and utilization of the national R&D information. In this paper, the concept of the identification metadata for applying the identification system and the status of the information management by each institute will be the subject for discussion. Based on this, the elements required for issuing a unique identification number and identifier to the national R&D projects will be suggested in this paper.

Video documents which have audio-visual and other semantics information have complex relationship among media. While user requests for topic retrieval or specific region retrieval increase, it is difficult to meet these requests with the existing design methodology, In order to support the systematic management and the various retrieval capabilities of video document, we must formulate structural and systematic model on metadata using semantics and structural informations which are abstracted automaticallv or manuallv. This paper suggests generic metadata model with which we analyze the characteristics of video document, supports various query types and serves as a generic framework for video applications, we propose the generic integrated management model(GIMM)for generic metadata,, design video documents management system(VDMS) and implement it using GIMM.

Big data analysis refers the ability to store, manage and analyze collected data from an existing database management tool. Meta-analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. We conducted a meta-analysis and review of between external factors on perceived value in e-commerce researches. This study focused a total of 11 research papers that established causal relationships between external factors on perceived value in e-commerce published in Korea academic journals during 2000 and 2016. Based on these findings, several theoretical and practical implications were suggested and discussed with the difference from previous researches.

디지털 정보환경 하에서는 이용자가 정보를 찾아오기 기다리기 보다는 이용자를 찾아가 수요를 창출하고, 이용자의 취향에 맞춘 정보제공이 필요하다. 본 연구에서는 연구장비정보의 효율적인 정보제공을 위해 푸시(push)와 풀(pull) 서비스를 통합한 맞춤정보 서비스 모델을 제시하고, RSS(Really Simple Syndication) 2.0과 Dublin Core Metadata Element Set 1.1을 참고하여 연구장비정보의 RSS-XML 메타데이터를 설계한 후, 풀(pull) 형태의 선택적 정보제공(SDI)시스템을 구현하여 이를 적용하였다.

Recently enterprises introduce EAI systems and legacy business which already obtained for data integration among legacy systems. EAI systems in cooperative transaction environment can be expected efficient retrieval as sharing and integrating. However existing legacy systems have to introduce particular EAI solution because it is difficult to adjust standard technology to EAI due to be managed independently without considering interoperability. For solving these problems we use metadata registry using data integration. Various types, semantic specification data heterogeneity and heterogeneity of systems, however, are occurred. Therefore retrieval system based on XMDR(extended Meta-Data Registry) for data interoperability in the web environment are proposed in this paper.

A biological data acquisition based on web has emerged as a powerful tool for allowing scientists to interactively view entries form different databases, and to navigate from one database to another molecular-biology database links. In this paper, the biological conceptual model is constructed hybrid biological data model to represent interesting entities in the data sources to applying navigation rule property for each biological data source based on four biological data integrating layers to control biological data. When some user's requests for application service are occurred, we can get the data from database and data source via web service. In this paper, we propose a query processing model and execution structure based on integrating data layers that can search information on biological data sources.

In this paper, we present the system that user can search and manage data using united interface and user can define search field dynamically. The feature of this system is that it is possible to manage multiple polymorphic meta information first. Second, there is a database integration bus that can support easy integration between the various systems. Third, it is possible to set the search item for each user which can customize polymorphism data for each user. The system studied in this paper is expected to be capable of managing big data, which is currently well received in the field of ICT. In addition, it will be possible to effectively manage multi-species polymorphic data in various fields in the future and to easily integrate between systems having various environments.

The output and usage rate of audio-visual materials have sharply increased as the information industry advances and diverse archives became available. However, the awareness of the audio-visual archives are more of a separate record with collateral value. The organizations that hold these materials have very weak system of the various areas such as the categories and archiving methods. Moreover, the management system varies among the organizations, so the users face difficulty retrieving and utilizing the audio-visual materials. Thus, this study examined the feasibility of the synchronized management of audio-visual archives by comparing the descriptive elements of the audio-visual archives in internal key agencies. The study thereby examines the feasibility of the metadata element of the organizations and that of synchronized management to propose the effect of the use of management, retrieval and service of efficient AV materials. The study also proposes the improvement of descriptive element of metadata.
