Abstract

As web 2.0 becomes one of the important architecture styles, more web applications adopt single page structure instead of multiple web pages and navigations between pages. A single page web application client, called a mashup client in this paper, interfaces more than one services and allows users to navigate in the page. A mashup client page includes complicated functions and has to handle various styles of services and user requirements, and therefore is usually developed manually. In this paper, we propose a model driven code generation approach for in-page navigations. We propose a page model and view navigation design approach, applying REST service architecture patterns. Then, we consider type conditions for each view to have service calls or navigation controls. Also, we developed an XForms page code generation system to demonstrate the efficiency of the proposed method. The developed system generates mashup client pages including navigation controls between services and views. This system can generate ready to use codes from service specifications, so this can help to reduce the development overhead. Moreover, our approach is based on formal model and navigation patterns so the generated result code is simple and easy to understand, and includes only the necessary controls. Therefore, the proposed approach can be more effective for the case of a large number of services.

웹 2.0의 확산과 함께 기존의 페이지 간 이동 대신 하나의 페이지에서 여러 개의 웹서비스를 인터페이스하는 웹페이지가 많이 사용되고 있다. 이러한 클라이언트 페이지를 매시업 클라이언트라고 부르는데, 이들은 복잡하고 다양한 기능을 지원하는 제어부를 포함한다. 본 논문에서는 이동 제어의 모델 기반의 코드 생성 방법을 제시한다. 먼저 REST 서비스 패턴을 클라이언트 페이지의 뷰와 뷰 이동에 적용하는 방법을 제안하고, 각 뷰로부터 서비스 메소드 호출이나 뷰 이동이 가능한 타입 조건을 제시한다. 또한 제안된 방법을 적용하여 XForms 페이지의 코드를 자동생성하는 프로토타입 시스템을 개발하였다. 이동 설계 방법을 적용한 매시업 클라이언트 페이지 생성 시스템을 구현하였다. 개발된 자동 생성 시스템은 개발자의 관여 없이 이동 제어 기능을 포함한 클라이언트 페이지의 코드를 생성하며, 체계적인 모델과 이동 패턴에 기반하여 생성된 결과 코드가 이해하기 쉽고 간단하다. 또한 사용자가 필요한 컨트롤만을 포함하여 서비스의 개수가 많아지는 경우에도 적용할 수 있다.
