소프트웨어 개발 프로세스 진행 중 산출 문서를 제작에 많은 시간적 비용이 필요하다. 또한 빈번한 데이터 또는 템플릿이 변경으로 수정 비용이 추가적으로 발생된다. 만일 개발 프로세스 과정에 PAL을 적용하여 자동 문서 생성이 가능하여 시간적 비용을 감소시킬 수 있다. 이를 위해, XML와 XSLT 기반의 PAL 엔진 설계 방법을 제안한다. 또한 표준 언어를 사용함으로써, 첫째로 시스템 관리자가 쉽게 문서 템플릿을 수정 가능하며, 둘째로 기존 시스템에 빠르게 적용 할 수 있다. 추가로 HTML 코드로 문서를 생성하여 일반 웹 브라우저에서 결과 문서 출력이 가능하다.

Recently, XML has been widely used as a standard for a data exchange, and there has emerged the tendency that the size of XML document becomes larger. The data transfer can cause problems due to the increase in traffic, especially when a massive data such as Data Warehouse is being collected and analyzed. Therefore, an XMDR wrapper can solve this problem since it analyzes the tree structures of XML Schema, regenerates XML Schema using the analyzed tree structures, and sends it to each station with an XMDR Query. XML documents which are returned as an outcome encode XML tags according to XML Schema, and send standardized messages. As the formalized XML documents decrease network traffic and comprise XML class information, they are efficient for extraction, conversion, and alignment of data. In addition, they are efficient for the conversion process through XSLT, too, as they have standardized forms. In this paper we profuse a method in which XML Schema and XMDR_Query sent to each station are generated through XMDR(extended Meta-Data Registry) and the generation of products and XML conversion occur in each station wrapper.

This paper proposes how to support various media on online conversational activity using XML(extensible Markup Language). The method converts media information into XML based messages and handles alike conventional text based messages. The XML based messages are unified to an XML document, and then a HTML document is generated using the XML and an XSLT documents in a server. A user in each client can play or present media through the hyperlink that is associated media information on the HTML document. The suggested method supports use of various media (text, image, audio, video, documents, etc) and efficient maintenance of font size, color, and style on messages according to extension and modification of XML tags. For application, this paper implemented the system to support media that has client and server architecture on online conversational activity. A user in each client inputs text or media based message using JAVA applet and servlet on the system, and conversational messages on every users' interfaces are automatically updated whenever a user inputs new message. Media on conversational messages are played or presented according to a user's click on hyperlink. Applications for the media presentation are as follows : distance learning, online game, collaboration, etc.

With the rapid development of internet technology, the number of internet users and the amount of multimedia information on the internet is ever increasing. Recently, the web sites, such as e-business sites and shopping mall sites, deal with lots of image information. As a result, it is required to support content- based image retrieval efficiently on such image data. This paper proposes an intelligent image retrieval system, which adopts XML, technology. To support object-based col)tent retrieval on product catalog images containing multiple objects, we describe a multi -level metadata structure which represents the local features, global features, and semantics of image data. To enable semantic-based and content-based retrieval on such image data, we design a XML-Schema for the proposed metadata and show how to represent such metadata using XML- documents. We also describe how to automatically transform the retrieval results into the forms suitable for the various user environments, such as web browser or mobile browser, using XSLT The proposed scheme can be easily implemented on any commercial platforms supporting XML technology. It can be utilized to enable efficient image metadata sharing between systems, and it will contribute in improving the retrieval correctness and the user's satisfaction on content-based e-catalog image retrieval.

소프트웨어 프로덕트 라인은 핵심 소프트웨어 자산의 개발을 위한 도메인 공학과 실제 소프트웨어 부품을 조립하여 구체적인 소프트웨어 시스템을 개발하는 응용 공학을 포함한다. 소프트웨어 프로덕트 라인 구축 시 가장 중요한 점은 특정 도메인에 존재하는 가변성(variability)을 지원할 수 있어야 한다는 것으로, 재사용자의 목적에 따라 효율적으로 소프트웨어를 맞춤 생산할 수 있는 컴포넌트 재구성성(reconfigurability)이 핵심 요소라 할 수 있다. 본 논문에서는 재사용자가 선택한 특성 구성을 바탕으로 계층 구조 조립 자동화를 통해 컴포넌트 코드를 자동 생성하는 도구를 구현하였다. 이를 위하여, 컴포넌트 패밀리의 특성 모델에서 표현되는 차이점에 따라 계층 구조의 각 컴포넌트들이 조립되도록 XSLT 스크립트를 사용하였다. 특성 모델과 XML/XSLT 기술을 이용하여 컴포넌트 코드 생성 시에 재구성성을 지원하고 재사용자의 요구에 맞는 컴포넌트 소스 코드를 자동 생성함으로써 소프트웨어 프로덕트 라인 개발 생산성을 향상시킨다.

Recently for software development productivity a lot of researches in the field of software engineering hove focuses on the component-based software product lines which allows the reuse of forger-granularity software components Its purpose is to develop the specific software application of quality more rapidly by instantiating and assembling the components populated in software product line assets The essential part to build the component-based software product lines is the quality of components, and one of the most important features determining the quality of components is 'reconfigurability' Component reconfigurability means the extent to which the reusers can change the functions and architecture of the component according to their context and environment. This paper proposes the component code generation technique which provides the reconfigurability at the time of code generation using The feature diagram and XML/XSLT technologies The approach of this paper allows the component reusers to get automatically their own component source code by providing only the values of variabilities represented in the feature diagram of the component family. The real world example, the code generation system for o list container family, shows the applicability of the feature model and XML related technologies in the area of the generative programming. Our approach should be basis to build the component based software product lines and extensible to support the larger graularity components.

In this paper, XML form generator is designed and implemented on the basis of e-business's DTD (Document Type Definition) document. Rapid evolving for internet services and information infrastructure give many impacts on the e-business, it need to make a new kinds of web-based or electronic-based document formats for e-business transaction trading. In current situations, there are many kinds of document formats on conventional business documents for each companies. And, it has many problems on the aspects of the document reusability and cost to support interoperability between documents for the trading partners. To solve this interoperability of documents, the constructed XML form generator is changing XML form document into HTML (HyperText Markup Language) based web document by XSLT. And it also generates XML business message validating for e-Business DTD by user Inputs.

XPath는 XML 문서를 탐색하고 필요한 부분을 추출하는데 유용한 W3C 표준 프로그래밍 언어이다. XPath를 기반으로 XSLT, XQuery와 같은 표준 언어가 정의되어 널리 사용되고 있으며, DTD, XML Schema, RelaxNG와 같은 타입 언어를 이용하여 XML 문서를 효과적으로 명세할 수 있음에도 불구하고, XPath 기반 XML 처리 프로그램을 위한 타입 검사 기법은 미비하다. 본 논문에서는 XPath 기반 프로그램을 위한 새로운 양상논리 기반의 타입 추론 기법을 제안한다.

XML-based network management, which applies XML technologies to network management, has been proposed as an alternative to existing network management. The use of XML in network management offers many advantages. However, most existing network devices are already embedded with simple network management protocol (SNMP) agents and managed by SNMP managers. For integrated network management, we present the architectures of an XML-based manager, an XML-based agent, and an XML/SNMP gateway for legacy SNMP agents. We describe our experience of developing an XML-based network management system (XNMS), XML-based agent, and an XML/SNMP gateway. We also verify the effectiveness of our XML-based agent and XML/SNMP gateway through performance tests. Our experience with developing XNMS and XML-based agents can be used as a guideline for development of XML-based management systems that fully take advantage of the strengths of XML technologies.
