This paper proposes a method of generating XSLT scripts, which support the fast transformation of XML documents, given one-to-one matching relationships between leaf nodes of XML schemas. The proposed method consists of two steps: computing matchings between cardinality nodes and generating XSLT scripts. Matching relationships between cardinality nodes are computed by using Proposed lexical and structural similarities. Based on the cardinality node matching relationships, an XSLT script is generated. Experimental results show that the proposed method has generated XSLT scripts that support the faster transformation of XML documents, compared with previous works.

XML been using extensively by standard of data exchanging in the Internet is observed by a technology to replace existent document creation language of HTML etc. Biggest characteristic of this XML is that logic information and physical information that express style of document that do that express structural substance of document were detached. Hereupon, W3C advised XSL that oner style function of form similar to HTML for XML's style and data conversion. Also, XSL's conversion function offers function that change XML document to other data format, and can describe style information through conversion of various document format. But, a XML document conversion technology that use XSLT know-how in domestic is unprepared real condition, and necessity about solution that can edit XSLT document efficiently is putting. This paper does XML document so that conversion and output are available in various document format. And offered research of XSLT document editing system that can edit and create XSLT document efficiently under WYSIWYG environment.

XML(extensible Markup Language) of W3C(World Wide Web Consortium) that is used the standard core technology of data exchange on the current Internet is an independent data type of usable at the all platforms. Especially, it can handle rapidly because of the integration of each other data types that is exchanged. Between each application and system that built at an enterprise in the past. However, W3C had notice to use XSLT(extensible Stylesheet Language Transformation) that is document transformable standard to descript expression information in XML documents because documents of XML only have a logical structure information. It is designed for XML that is developed for data exchange on the internet. Moreover, it is proposed to process and to change as other data type for expression XML documents for user. This thesis design and implement XSLT document editing system transformable as a un data type as a HTML data type applying XSLT at XML and developed the system. It can edit XSLT document that descript expression information in XML document that is used for data editing in the WYSIWYG environment.

XML은 텍스트를 기반으로 하는 데이터 표현의 표준이다. 하지만, 이진 데이터 저장 방식에 비해 파일에 크기가 커서 자원을 적게 사용하는 편재형 컴퓨팅 환경에 적용하기 어려운 단점을 가진다. EXI는 XML의 형태는 그대로 유지하면서 파일의 크기를 줄이는 이진 XML 의 W3C 표준이다. 한 응용에서 사용하고 있는 XML 을 다른 응용에서 재사용하기 위해서는 변환이 필요하고, 일반적인 XML 문서의 변환에는 XSLT가 이용된다. 하지만, XSLT는 텍스트를 기반으로 하고 있어 EXI 포맷에 바로 적용할 수 없다. 본 논문은 자원을 적게 사용하는 편재형 컴퓨팅 환경에서 EXI 포맷 XML 문서의 재사용성을 높이기 위해 서로 다른 응용의 EXI 포맷 XML 문서의 변환 방법을 제안한다. 그리고, 다양한 응용환경 중 EXI 포맷의 XHTML 문서를 EXI 포맷의 VoiceXML로 변환하는 시스템을 보인다. 이는 자원이 적은 편재형 컴퓨팅 환경에서 EXI 포맷 XML 문서의 재사용성을 높이고 EXI 포맷 XML 활용에 기여할 수 있다.

XML 문서를 변환하는 목적은 하나의 어플리케이션에서 사용되는 XML 문서가 다른 어플리케이션에서 재 사용될 경우, 사용자에게 동일한 정보를 제공하는데 있다. 문서를 변환하기 위해서는 변환 규칙을 정의해야 한다. 변환 규칙을 생성하기 위해서는 엘리먼트의 정보를 분석하여야 하는데 한 가지 방법으로는 엘리먼트의 정보를 분석하기 어렵다. 그러므로 본 논문은 변환 규칙을 생성하기 위한 엘리먼트 분석으로 다수의 방법을 사용할 수 있는 XSLT 편집기를 제안한다. 본 시스템은 XML의 구조적 특성인 엘리먼트의 포함 관계와 플러그인 방식으로 유사 엘리먼트를 분석하여 사용자에게 제공하는 방법을 보인다. XML의 엘리먼트 구조는 엘리먼트가 표현하고 있는 정보간의 구조와 동일한 구조로 포함되어 있다. 또한, 플러그인 방식 포함할 수 있는 모듈로는 문법적 특성을 이용한 방법을 포함하거나. semantic web의 정보를 이용하는 방법을 추가할 수 있다 또한 기존의 XSLT 처리기를 내장하고 있어 XSLT 문서를 변환 XML에 적용하여 피 변환 XML 문서를 생성할 수 있다. 제안하는 시스템은 기존의 사용자가 사용 패턴을 분석하여 엘리먼트를 분석하고 변환 규칙을 기술하는 방법과 달리 유사한 엘리먼트에 대한 정보를 사용자에게 제공하는 장점이 있다.

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

As computer-related technologies have been developed, legacy design systems have not been appropriate for new computing environment. Therefore, it is necessary that most of them are either modified or newly developed. However, this requires quite much amount of cost and time. This paper presents a method of extending legacy design system without modification using XML and XSLT. In order to apply the developed method, a good example of legacy design systems, AGMA gear rating system has been extended so as to be suitable for the distributed computing environment. An XML document for AGMA gear rating process is defined. It is transformed to the form of the input document of AGMA gear rating system by XSLT processor according to the transformation rules defined in the AGMA gear rating XSLT document. After that, AGMA gear rating system reads this input document and generates an output document in the server. These operations are automatically executed by the external legacy system controller without user interactions. Using these operations, AGMA gear rating web service has been developed based on SOAP and WSDL to provide the functions of legacy AGMA gear rating system through the distributed network. Any system or user can implement AGMA gear rating process independently to the platform type, without making it for oneself, by simply referring the AGMA gear rating web service via Internet.

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.
