The OAI(Open Archives Initiative) is an evolving protocol and philosophy regarding interoperability for digital libraries. This protocol has its roots in an effort to enhance access to digital libraries as a means of increasing the availability of scholarship communication. Thus, this research outlines the history of the OAI protocol, the basic model of SP(service provider)/DP(data provider), and the prerequisites to implement the OAI protocol. Viewed in this light, this paper also describes the experiences of KERIS project of SP/DP model and lists the differences between prerequisites and KERIS case.

Many contents produced and provided as development of information technology on the internet. Especially discussion that collecting and storing of digital information resources, is expanded as growing dependence on academic information of research workers. Open Access is a new paradigm of information distribution that is opposite concept of high price distribution academic information. It is an OAI system that is intended to collect and automate open access data in good order. This paper constructs stOAI based on OAI that is a science and technology information providing system. This system provides international academic journal free of charge that collect and store through OAI protocol in OA(Open Access) of yesKISTI(science and technology information portal service). Also, It provides automate and centralize science technology information, that KISTI has, to external institution as a standard type.

최근까지 개발되어 사용되고 있는 대부분의 P2P 파일 검색 및 공유 시스템들은 파일 이름과 확장자를 이용한 단순 키워드 검색 방식을 취하고 있다. 점점 기술이 발전되고 많은 정보가 쏟아져 나오면서 많은 자료 중에서 필요한 정보를 빠르고 쉽게 찾을 수 있는 능력이 필요하게 되었다. 또한 단순히 파일 검색을 떠나 컨텐츠를 공유하고 배포하는 경우 파일의 이름만을 가지고는 파일의 역할과 내용을 알 수 없어 파일에 대한 정보를 담는 메타데이터에 관한 연구와 그 중요성이 증가하고 있는 상황이다. 본 논문에서는 P2P 파일 공유 및 검색 시스템에서 검색의 정확성과 효율성을 높일 수 있도록 메타데이터를 이용한 파일 검색 시스템을 제안한다. 이를 위해 메타데이터로 자료의 검색이 가능한 OAI 프로토콜을 이용하였고 제안한 시스템을 구현해 실험해보았다.

OAI는 간단한 프로토콜을 정의함으로써 디지털도서관 사이의 상호이용의 문제점을 해결하기 위해 제시된 프로토콜이다. OAI를 통해 디지털도서관사이의 상호이용을 가능하게 하기 위해, 디지털도서관이 가지고 있는 컨텐츠에 대한 메타데이터를 제공하기 위한 data provider와 이를 수집하여 유용한 서비스를 제공하기 위한 service provider라는 두개의 프레임웍이 필요하다. 본 논문에서는 OAI protocol을 따르는 많은 data provider들이 가지고 있는 정보들을 수집하고 수집된 정보를 통해 새로운 서비스를 제공하는 service provider의 기능을 설계 및 구현하였다.

This study examined the main concepts of SOA and Web Services, and conducted technical analysis of major Web Services protocols such as SOAP, REST, SRW/U, and OAI-PMH that realize SOA, and suggested examples of SOAP and REST based Web Services establishments in foreign and domestic libraries respectively. In addition, it introduced application examples of Library 2.0 using Web 2.0 technology in foreign and domestic libraries and suggested how to apply SOA based Web Services protocol in Library 2.0. Finally, it proposed how to put Library 2.0 into practice applying meta-searching system integrating library OPAC, online bookstores, web portal sites and library union catalogs using REST based Open API.

In current web-based systems, it is generally recognized that one way flow of information from providers to users can cause the static problem of document structure. Therefore, information update frequency and interaction between providers and users are quiet slow. Monopolized information can obstruct the free user's access and heterogeneous format and different protocols also make users difficult to retrieve and to collect information. To resolve these problems, in this study, we introduce the Web 2.0 to move toward the user's participation and share based on the social network and the OAI protocol to improve the free access and the interoperability on bibliographic information for Life Science and then design the bibliographic information network for life science. This network has four main functions such as: 1) Open Repository function that can make up user community for sharing and data exchange. Data such as article, seminar material, research note and research report are considered in design. 2) Open Collection function that can collect and store the metadata on distributed bibliographic information networks, 3) Open Access function that can manage the metadata in the open access environment, and 4) Administration function that can monitor the user activity and statistics and can inspect the registered data.

The purpose of the study is to implement the management model of the institutional repositories for the efficient distribution infrastructure of national knowledge focusing on the dCollection system which is operated by KERIS (service provider). In order to build the management model, the two steps were utilized. The first step is to investigate the checklists of repositories that are important factors for the successful repository implementation through literature review. On the other hand, the second one is to survey the current status of the sixteen domestic and foreign institutional repositories through interviews, surveys and email as well as the repository home pages and literature reviews. Through the two steps, the management model including six components such as content and librarian role was proposed. The proposed management model will be utilized to supply guides both to the universities which plan to build their institutional repositories and to the universities which try to promote the activities of their repositories.

웹 서비스는 표준화된 XML 메시지를 통하여 네트워크에 연결된 기계간에 상호작용 위하여 고안된 분산 컴퓨팅을 지원하는 기술이다. 일반적으로 웹 서비스를 구성하는 프로토콜 중 SOAP은 현재 웹 서비스의 메세징 프레임웍을 정의하는 프로토콜의 표준으로 사용되고 있지만 REST의 경우 전송방식이 개발에 용이하고 사용이 편리하여 앞으로 구축이 활발해질 전망이다. 또한 SRW/U, OAI-PMH는 웹 기반 정보검색을 표준화된 방식으로 수행하도록 규정하는 웹 서비스 프로토콜이다. 본 논문에서는 웹 서비스의 다양한 프로토콜에 대한 기술을 소개하고 이에 대한 비교 분석을 통하여 장단점을 살펴본다.
