XML is being used to describe components and applications in a vendor and language neutral. Therefore it already has a role in distributed system. XML is also being used as a data interchange format between components and applications in loosely coupled large-scale application. Until now, policy is described for specific applications and devices. Its use has been very limited. In current network management system, we can only invoke predefined operations and actions using policy-based network management. The main motivation for the recent interests in policy-based networks is to support dynamic adaptability of behavior by changing policy without recoding or stopping system. For these reasons we present the use of the XML for describing the policy and PIB(Policy Information Base) in COPS-PR. It improves flexibility and interoperability among heterogeneous network systems. It also can add new functionality into network components. In this paper, we propose a dynamically extensible network management architecture using XML-based PIB.

최근 IT분야의 보안 분야와 함께 생체인식 분야는 급성장하였으며 국내외에서 생체인식 소프트웨어에 대한 시험 인증 수요가 증대되고 있으나 생체인식 소프트웨어에 대한 품질을 평가할 수 있는 방법에 대한 연구는 미흡한 실정이다. 생체인식 소프트웨어의 품질시험과 평가를 위한 기준으로 평가모듈(Evaluation Module)이 도출되어야 하며, 평가모듈을 효율적으로 공유하거나 교환하기 위해 XML를 이용할 수 있다. 또한, 생체인식 소프트웨어의 인증과정과 관련된 문서들은 다양한 스타일로 구성되어 있으며 평가대상에 따라 관련문서들의 스타일도 변경되어야 한다. 본 논문에서 XML 기반 평가모듈에 XSL(eXtensible Stylesheet Language)을 이용하여 여러 스타일 시트로 적용할 수 있도록 XSL 스타일 편집기를 설계하였다.

네트워크상에서 멀티미디어 컨텐츠(디지털 아이템)를 다양한 전송 매체(인터넷, 방송 무선전화 등)를 통해 전달하고, 서로 다른 기능의 단말기(PDA, PC, TV, Phone 등)를 통해 디지털 아이템을 소비하는데 있어 상호호환성(Interoperability)을 제공하기 위해 디지털 아이템의 생성, 전달, 소비 단계에 이르기까지 디지털 아이템의 규격을 제정하고자 MPEG-21(멀티미디어 프레임워크)이라는 이름의 국제 표준화 작업이 진행 중이다[1]. 본 논문에서는 MPEG-21의 디지털 아이템 선언 언어인 DIDL(Digital Item Declaration Language)을 이용하여 컨텍스트 디지털 아이템(XDI: conteXt Digital Item)을 XML 문서형태로 생성하고, 이를 컨텐츠 디지털 아이템(CDI: Content Digital Item)의 종류(영화, 음악, 도서, 게임 등)에 구애받지 않고 웹 브라우저를 통해 소비할 수 있는 디지털 아이템 브라우저를 구현하였다. 디지털 아이템의 다양한 형태에 적절히 대응하기 위해 XSLT(XML Stylesheet Language Transform)를 이용하여 디지털 아이템 정보를 표현하고 웹 브라우저를 통해 소비자의 환경에 적합한 디지털 아이템을 소비 및 이용할 수 있는 어플리케이션을 제공하는 환경에 대한 연구 결과를 제시한다.

As computer-related technologies have been developed, legacy design systems have not been appropriate far new computing environment. It is necessary that most of them are either modified or newly developed. However, these activities require quite much amount of cost and time. This paper presents a method of extending legacy design systems to the internet without any modification using XML and XSLT. We have been extended legacy systems in the two viewpoints. First, an XML document has been defined to present the input information of a legacy system which is executed on the consol environment - MS DOS, for example. Also, an XSLT document has been generated to transform an XML document to the input document of the legacy system An XML document is transformed to the input document by XSLT processor according to the transformation rules defined in the XSLT document. This technique to generate input documents is independent to the platform type and facilitates to link legacy systems to other systems. Second, a legacy system controller has been made to control a legacy system and developed a web service to extend it and its controller. The legacy system controller operates it automatically. The web service provides its functions to other systems via internet. We have applied the developed methodologies to the legacy gear design system 조ich calculates AGMA gear rating md made AGMA gem rating web service.

Last days, various kinds of applications and system were individually introduced into specific groups or enterprises by different objective without considering interoperability among those. However, the environment for data processing is changing rapidly in these days. And now the necessity is growing to integrate and couple applications and system in the process dimension for more flexible and quicker data processing on these application programs and system. When integrating these application programs or system, an integration based on XML is recommended as it is one of good methods which will the additional cost and satisfy the requirements of the integration. This is because the XML is not only device-independent data type which can be used any platform, but also it uses XSLT, the document conversion standard established by W3C, which allows easy data conversion from one to another type on occasion of demands. This paper studies a design and implementation of system to convert XML structure. This system shows the structure of source- side providing data and destination-side processing data with using XML schema that defines structural information of a XML document. And this system defines the structure relationship of desired form as mapping structural information and data. This system creates the XSLT document that defines conversion rule between two structures based information which is defined. The XSLT document which is created as described above will convert data to be appropriate to the structure of the destination- side. By implementing this system, it is able to apply a document into various kinds of structure without considering specific system or platform and it is able to construct XSLT document to which meaning of desired form can be given. This paper aims to offer a process conversion between documents and to improve interoperability and scalability, so that we can contribute to build XML document processing environment

An electric vehicle (EV) not only receives electric power from the electric vehicle supply equipment (EVSE), but it also exchanges the information regarding charging process with the power gird through the EVSE. However, the EV and EVSE communicate using the ISO/IEC 15118 standard while the EVSE and power grid communicate using the IEC 61850 standard. Therefore, the EVSE should support both the ISO/IEC 15118 and IEC 61850 standards, and provide a data mapping function between the two communication protocols so that the EV and power grid, which support different protocols, can communicate with each other throughout the charging process. In this paper, we propose a mapping method of the EVSE, which converts the ISO/IEC 15118 data to IEC 61850 and vice versa, based on the XML schema of each protocol. The proposed method converts the data using the XSL (eXtensible Stylesheet Language) method, which defines the data mapping between two XML schemas. Our approach is more flexible and easier to maintain against changes in charging scenarios and the standards than other existing approaches such as one-to-one data mapping methods.

웹 기반의 교육의 활성화로 이를 학습에 응용하기 위한 노력으로 GVA(Global Virtual Academy) 등과 같은 학습 보조 도구가 많이 발표하고 있는 설정이다. 대부분의 학습 보조 도구들은 각각의 특성들만 제시할 뿐 통합된 표준호가 되어 있지 않다. 최근 가상교육에서 학습기술이 상호운용성에 기반한 표준화의 일반적인 필요성을 인식하게 됨에 다라 가상교육의 국제표준을 소개하고 체계적으로 AICC(Aviation Industry CBT Committee), IMS Global Learning Consortium, ADL(Advanced Distributed Learning)을 중심으로 진행되어 오고 있다. 웹 기반의 교육을 통한 질의 응답의 학습방법을 고려한 도구가 없으므로 질의 응답 학습 도구(QALT)지원을 위한 표준화된 LTSA(Learning Technology Standard Architecture) 기반 시스템을 학습 객체에 대한 질의 응답과 개방형 단순 질의 응답 측면으로 구현한다. 그러므로 개방형 단순 질의 응답 측면을 구현하기 위해 학습 기술의 표준화로 제시되어 있는 LOM(Learning Object Metadata)을 통해 설계 자체를 체계화하고 전체적으로 명세 작업을 가능하게 하여 일관성을 유지하는 정련화된 문서로 질의 응답할 수 있도록 한다. 또한, Web 상에서의 Network delivery와 DTD(Document Type Definition)와 Stylesheet를 사용자가 쉽게 수정 가능하며 다양한 Linking Type을 제공하므로 단순 질의 응답 문서의 형식을 XML로 한다
