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.

본 논문에서는 XML 문서간의 자동 변환을 위한 효율적인 XSLT 스크립트를 생성하는 알고리즘을 제안한다. 제안된 방법은 XML DTD를 구성하는 단말 노드간의 일대일 대응관계가 주어져 있다는 가정 하에 XSLT 스크립트를 생성하는데 중점을 둔다. 제안된 알고리즘은 상향식과 하향식의 복합적인 접근 방식을 적용한다. 먼저 중간 노드간의 대응관계를 상향식으로 생성하며 하향식 깊이 우선 탐색을 적용하여 XSLT 스크립트를 생성한다. 실험결과, 제안된 방법은 기존 연구와 비교하여 XML 문서를 보다 빠르게 변환하는 XSLT 스크립트를 생성하였다.

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.

An EVSE and the EV exchange XML formatted communication messages with each other, whose structure is described by the V2G CI schema in the ISO/IEC 15118 international standard, and the EVSE and the power grid exchange messages based on SCL file with each other, whose structure is described by SCL schema in the IEC 61850 international standard. Because XML files can be restructured by XSLT, V2G messages can be transformed to/from SCL files using XSLT. In this study, the two schemas are analyzed and compared in order for the restructuring of the two differently structured XML instances. As a result, two XSL scripts can be produced for the transformation between XML files conforming ISO/IEC 15118 V2G CI schema and IEC 61850 SCL schema respectively to avoid manual data mapping which can happen in every application development cases.

Recently a lot of researches on the component-based software product lines and on applying generative programming into software product lines are being performed actively. This paper proposes an automatic component reconfiguration tool that could be applied in constructing the component-based software product lines. Our tool accepts the reuser's requirement via a feature model which is the main result of the domain engineering, and makes the feature configuration from this requirement. Then it generates the source code of the reconfigured component according to this feature configuration. To accomplish this process, the component family in our tool should have the architecture of GenVoca that is one of the most influential generative programming approaches. In addition, XSLT scripts provide the code templates for implementation elements which are the ingredients of the target component. Taking the ‘Bank Account' component family as our example, we showed that our component reconfiguration tool produced automatically the component source code that the reuser wants to create. The result of this paper would be applied extensively for creasing the productivity of building the software product lines.

Software product-lines is the software development paradigm to attain the rapid development of quality applications by customizing the reconfigurable components and composing them based on predefined software architectures. Recently various methodologies for the component-based product lines are proposed, but these don't provide the specific implementation techniques of the components in terms of variability resolution mechanism. In other hand, the several approaches to implement the component supporting the variabilities resolution are developed, but these don't define the systematic analysis and design method considering the variabilities from the initial phase. This paper proposes the integration of PLUS, the one of product line methodologies extending UML modeling, and component code generation technique in order to increase the efficiency of producing the specific product in the software product lines. In this paper, the component has the hierarchical architecture consisting of the implementation elements, and each implementation elements are implemented as XSLT scripts. The codes of the components are generated from the feature selection. Using the microwave oven product lines as case study, the development process for the reconfigurable components supporting the automatic variability resolution is described.
