웹 자원을 효율적으로 관리하기 위해서 메타데이타(metadata)의 활용이 증가하고 있으며, 이 활용 분야 중 웹사이트 관리를 위한 응용들은 표준화되지 않아서 상호호환성의 문제를 가지고 있다. 따라서 본 논문에서는 메타데이타의 표준화와 상호운영을 목적으로 하는 RDF(Resources Description Framework)를 이용하여 웹사이트 관리를 위한 메타데이타 생성 시스템을 제안한다. 제안된 시스템은 웹사이트를 기관 도메인별로 자동 분류하고, 정보를 구조적 형식으로 기술하여 효율적인 검색 환경을 제시할 수 있다. 이를 위해 더블린 코어를 기반으로 한 메타데이타 모델 및 RDF 메타데이타를 자동 생생하기 위한 사상 규칙과 알고리즘을 제시하고 시스템을 구현한다.

이 논문에서는 ISO/IEC JTC 1/SC 32/WG 2에서 개발한 메타데이터 관리 표준에 대한 검증 및 활용성 향상 방안을 제안한다. 메타데이터는 데이터의 데이터라고 정의하며 데이터를 표현하기 위한 다양한 데이터를 의미한다. 메타데이터는 데이터에 대한 해석 및 처리를 보다 용이하게 하기 위한 정보로서, 데이터에 대한 정확한 이해를 통해 데이터 불일치 문제를 해결하기 위해 이용된다. ISO/IEC JTC 1/SC 32는 데이터 교환 및 관리를 위한 표준을 개발하며 특히 WG 2는 메타데이터 관리를 위한 다양한 표준을 개발한다. WG 2에서 다양한 많은 표준을 개발하였으나 검증 및 활용성 측면에서 몇 가지 한계를 지닌다. 따라서 이 논문에서는 WG 2에서 개발한 표준에 대한 검증 및 활용성 향상을 위한 방안에 대하여 서술한다.

The aim of this study was to analyze the research trends on the digital libraries in Korea. To achieve this objective, a total of 578 author-assigned English keywords were collected from the 272 major LIS journal articles published in Korea during last ten years-period, i.e., 2007-2016. The collected data were analyzed using NetMiner V.4 to discover their 'degree centrality' and 'betweenness centrality'. As the results, 'Academic Library', 'Reference Service', 'Public Library', 'E Resource', and 'E Book' showed the most frequently conducted research topics, and 'Academic Library', 'Reference Service', 'Information Behavior', and 'E Resource' were the most influencing research topics. Finally, 'Academic Library', 'Metadata', 'Information Behavior', 'E Resource', and 'Librarian' seemed the most widely intervening research topics in this research.

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.

There are many kinds of applications or software components to manage files in a local computer, but it is very difficult to organize personal documents in a consistent way and to search expected ones in a precise way. In this paper, we present our development of a document management and retrieval tool, which is named Ontalk. Our system provides a semi-automatic metadata generator and an ontology-based search engine for electronic documents. Ontalk can create and import various ontologies in RDFS or OWL for describing the metadata. Our system that is built upon.NET technology is easily communicated with or flexibly plugged into many different programs.

e-Transformation of an enterprise requires the collaboration of business processes to be suited to the business participants' purpose. To realize this collaboration, business processes should be implemented as components and the system developers could be able to reuse the components for their specific purpose. The first step of this collaboration is the discovery of exact components for business processes. A dilemma, however, is the fact that there are thousands or even millions of business processes which vary from one enterprise to another. Moreover, business processes could be decomposed into multiple levels of semantics and classified into several process areas. In general, discovery of exact business processes requires understanding of widely adopted classification schemes such as CBPC, OAGIS, or SCOR. To cope with this obstacle, business process metadata should be defined and managed regardless of specific classification schemes to support effective discovery and reuse of business processes components. In this paper, a methodology to discover business process components published in different semantic levels is proposed. The proposed methodology represents the metadata of business process components as topic maps stored in a registry and utilizes the powerful features of topic maps for process discovery. TM4J, an open-source topic map engine, is modified to support concept matching and navigation. With the implemented tool, application system developers can discover and publish the business process components effectively.

In smartphone sensing which monitors various social phenomena of the individuals by using embedded sensors, managing metadata is one of the important issue to process large-scale data, improve the data quality, and share collected data. In this paper, we proposed a document clustering scheme for the large-scale metadata management architecture which is designed as a hybrid back-end consisting of a cluster head and member nodes to reduce the server-side overhead. we also verified that the proposed scheme is more efficient than the distance based clustering scheme in terms of the server-side overhead through simulation results.

최근, IT 기술의 발달로 다양한 스마트 디바이스 및 서비스 증가로 빅 데이터 시대가 도래되었다. 이에 빅 데이터를 저장하기 위한 많은 연구들이 진행되고 있지만 데이터 저장을 위한 측면에 중점을 두어 본질적인 서버 운용에 대한 연구가 도외시 되고 없다. 또한, 기존의 서버 운용은 장애 발생시 페일 오버나 리던던시를 통해 대용을 하고 있지만, 이러한 기법은 연속적인 장애 발생에 대한 대응이 불가하다. 본 논문에서는 빅 데이터를 저장하기 위한 DSV(Desktop Storage Virtualization) 환경에서 서버 장애를 효율적으로 대응하는 M2S2(Metadata Management for Server Sustainability)를 제안한다. M2S2는 독립적으로 분산된 데스크당의 성능, 거리, 저장된 데이터양을 기준으로 최적의 대체 서버가 수행된다. 또한, 대체 서버의 장애 발생시 하위 데스크탑 중에 최적의 대체 서버가 수행 반복됨으로써 지속적인 서버 운용이 가능하다.

Festival records are valuable social records, not only historically but also culturally. Even though festival records are worthy of preservation, many of them are not managed appropriately. In particular, photographs taken by the public are dispersed in various SNS services such as Facebook, Instagram, and Twitter. This study collected festival photographs, taken by the public, from these SNS services and built a participatory archive for Daegu. As such, this study identified and suggested a metadata set through the process of archiving festival photographs. In addition, this study proposed a model of the participatory archive for festival photographs. This model illustrated the institute's collection of festival photographs in the SNS services and the creation of the participatory archive.

In the Urban Regeneration Project, the scale becomes huge and the composition of participating organizations is complex. It is necessary to establish the master plan fast and effectively harmonize conflict options and interests in the early stage of the project. However, the master planner, who is tasked to establish the master plan, and the master planning team, are difficult to establish the master plan fast while effectively considering various and complex information related to regeneration. The Urban Regeneration Project is composed of various types of computer files like HWP, EXL, PDF, DWG and others. When the master plan is established, it is necessary to link the information items and physical files of urban generation in order to effectively save the files in storage for easy search and utilization. This study developed a prototype system to support participating subjects of the Urban Regeneration Projects. It will effectively utilize the information items in the physical computer files using information blocks and Metadata. The developed system provides the base to effectively manage large amount of documents in the early stage of the Urban Regeneration Project and make effective decision-making using the concept of data warehouse.
