The purpose of this study is to present technical elements to improve the data utilization of the ISNI Korea Consortium, which is operated by the National Library of Korea, which is responsible for the registration of Korean names. The ISNI Korea Consortium aims to register various creation-related information in addition to bibliographic-related individual and organization name information. To this end, this study examines the ISNI Korea consortium, which is a data provider's consultative body, among other things, the metadata status of copyright organizations and the linked data specification of ISNI. As a result, data acquisition, refining, storage, identifier management, consortium metadata management, five in total, and RDF data management (repository) in terms of linked data, RDF data issuance, RDF data retrieval, RDF data inquiry, RDF data Eight technical elements, including download, ontology inquiry, standard term inquiry and mapping information management, were derived.

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.

RDF treats all resources independently, that's integrated description model for internet resources description, that provides the model to connect resources that related with the specific resources. This article performs theoretical review of RDF model and syntax specification and RDF schema specification that's a common rule of semanics, structure and syntax those provides search and access in the area of dispersed information environment of internet and Dublin Core that's description element for build metadata. And with this way it's materialized metadata design, schema, DTD of Dublin Core element for building RDF-based metadata that is XML application.

Recently, the semantic web stands out in the next generation web. To realize the semantic web, the metadata integration is required between different metadatas on the web for metadata management. Otherwise, the integrated structure is needed to accommodate all of semantic, syntax and structure. RDF is one of the core technology and is more efficient framework for technology and interchange of metadata in the web, In this paper, for metadata management, we designed and implemented the RDF authoring system which converts each of metadata into RDF and makes it easy to manipulate and manage the different metadatas. For this, we researched about the RDF creation using Dublin Core metadata, the conversion of XML document into RDF, the RDF expression by N-Triple form and the integration of WSDL and RDF, and implemented the system on the lava platform. Basically, users using this system can integrate and manage metadatas easily even if they are not expert.

시맨틱 데이터는 인간이 의도한 정보를 효과적으로 기계에게 전달하는 정보 양식이다. 그러나 시맨틱 정보를 웹 브라우저를 통해 CGI 코드로 처리하는 방식은 정보 시스템내의 정보구조와 이의 처리 코드가 고착되는 문제점을 안고 있었다. 이를 해결하기 위해 본 논문에서는 시맨틱 정보를 담는 RDF 술어를 기술하는 XML 스키마를 제안한다. 해당 스키마로 기술된 RDF 술어는 HTML 폼으로 자동으로 생성되며, 해당 폼에서 받아들인 데이터를 기반으로 대응되는 RDF 문서를 생성하는데 사용된다. 제안된 스키마를 이용함으로써, 정보 시스템 내에서 RDF 구조의 동적인 변경이 용이하며, 표준화된 방식의 RDF 데이터 입력이 가능해지는 효과를 얻게 된다.

In this paper, we propose an effective method to convert and construct the MEDLINE, the world's largest biomedical bibliographic database, into linked data. To do this, we first derive the appropriate RDF schema by analyzing the MEDLINE record structure in detail, and convert each record into a valid RDF file in the derived schema. We apply the dual batch registration method to streamline the subject URI duplication checking procedure when merging all RDF files in the converted record unit and storing it in a single RDF triple storage. By applying this method, the number of RDF triple storage accesses for the subject URI duplication is reduced from 26,597,850 to 2,400, compared with the sequential configuration of linked data in units of RDF files. Therefore, it is expected that the result of this study will provide an important opportunity to eliminate the inefficiency in converting large volume bibliographic record sets into linked data, and to secure promptness and timeliness.

The Basic Semantic Register(BSR) is and official ISO register designed for interoperability among eBusiness and EDI systems. The entities registered in the current BSR are not defined in a machine-understandable way, which renders automatic extraction of structural and relationship information from the register impossible. The purpose of this study is to offer a framework for designing an ontology that can provide semantic interoperability among BSR-based systems by defining data structures and relationships with RDF and OWL, similar meaning by the 'equivalentClass' construct in OWL, the hierachical relationships among classes by the 'subClassOf' construct in RDF schema, definition of any entities in BSR by the 'label' construct in RDF schema, specification of usage guidelines by the 'comment' construct in RDF schema, assignment of classes to BSU's by the 'domain' construct in RDF schema, specification of data types of BSU's by the 'range' construct in RDF schema. Hierarchical relationships among properties in BSR can be expressed using the 'subPropertyOf' in RDF schema. Progress in semantic interoperability can be expected among BSR-based systems through applications of semantic web technology suggested in this study.

RDF(Resource Description Framework)는 시맨틱 웹의 기초로서 웹 사용자에게 정보를 보다 정확하고 효율적으로 접근하는 표준이다. RDF 데이터를 효율적으로 저장하고 접근하는 필요성이 날로 증가하고 있다. RDF 데이터를 저장하고 검색하는 기본 저장 구조는 관계형 데이터베이스를 이용하는 것이다. 최근에는 RDF 데이터가 엄청나게 증가하고 있는 시점에 대용량 database의 질의(단순 조회)에 최적화된 칼럼-지향(column-oriented) 데이터베이스가 대안으로 제안되었다. 본 논문에서는 RDF 데이터의 저장 구조로서 관계형 데이터베이스와 칼럼-기반 데이터베이스를 비교분석 하고자 한다. Berlin SPARQL Benchmark 를 이용한 성능분석 결과 RDF data 의 저장 구조로서 칼럼-기반 데이터베이스의 효율성을 입증하였다.

The semantic web was proposed as the next generation web technology. In the environment of the semantic web, resources as well defined and related with each other semantically, the RDF supports this basic mechanism. To establish and develop the semantic web. the basic technologies related to RDF data must be pre-established. In this research, we develop methods for storing and querying RDF data using an XML database system. As using XML database, XML data and RDF data can be integrated and efficiently managed. We construct and evaluate a system applying the proposed method to store and search data, we compared the query processing performance on our system with that of an existing system. The experiment result show that our system processes queries more efficiently.
