  • One of the main issues in developing a digital library is how to implement an open digital library which can be interoperable, and diverse concepts, technology and protocols have been introduced to deal with this issue. In this study, it is analysed in terms of 'metadata interoperability', and based on the analysis, 5 basic component technologies are defined as follows: application profiles, modeling, implementation, resource discovery, portal service. Therefore it explains concepts of those core features, characteristics, cases in point, standardization and technical trends.

  • Computer simulation models are in general quite complex and time-consuming to run, and therefore, a simpler meta-model is usually constructed for further analysis. In this paper, JANUS, a war-game simulator, is used to describe a certain tank combat situation. Then, second-order response surface and artificial neural network meta-models are developed using the data from eight different experimental designs. Relative performances of the developed meta-models are compared in terms of the mean squared error of prediction. Computational results indicate that, for the given problem, the second-order response surface meta-model generally performs better than the neural network, and the orthogonal array-based Latin hypercube design(LHD) or LHD using maximin distance criterion may be recommended.

  • 클래스정보에 대한 속성의 추출 및 분류에서 주로 추출된 클래스의 정보가 단지 원시코드의 코멘트에서 추출되었기 때문에 클래스에 대한 정확한 기능 및 용도에 대한 Document가 부족하여 실제로 이용자가 최적의 부분을 추출하기가 어려웠다. 이러한 것들을 향상시키기 위하여 본 연구에서는 객체에 대한 클래스뿐만 아니라 패턴모델의 설계에서도 객체지향모델링 방법을 이용하여 메타모델과 메타데이터를 설계하였다. 그리고 XMI 메타모델로 정의된 디자인패턴의 세부적인 클래스의 메타데이터의 생성에 중점을 두었으며, 마크업언어로 XML-스키마 형식을 이용하여 심플타입(simple type)과 콤플렉스타입(complex type)으로 분류하였다. 그 결과 메타데이터 엘리먼트 단위영역별로 마크업언어를 생성하여 소프트웨어 설계에서 효과적인 재사용을 할 수 있었다.

  • Recently, the scope of user interface is increasing the relative importance in software development dramatically. As a result, there are various relative technologies like as SWING, MFC, Web 2.0, and etc. However, most current software developments are progressed in separate development process with user interface part and business part respectively. This causes the problems, like as a difficulty in the integration process, an development period's delay, and a poor reusability for the constructed models. That is, the extendability and reusability of the created models is being decreased because UI modeling is not systematic and hierarchical, and the consistent integration technique between UI modeling and business modeling does not supported. To solve these problems, this paper proposes an unified and systematic UI modeling process based on UML, using the hierarchical metamodel according to the abstraction levels of development phase. We suggest an UI metamodel, which contains a hierarchy by layering the modeling elements in PIM and PSM based on maturity degree of the development. An hierarchical modeling process combined UI modeling and business modeling is built by applying the UI and business metamodel in terms of three modeling phases(concept/specification/concrete). The effectiveness of the modeling process is shown by applying the proposed process into an Internet Shopping Mall System. Through the exploratory results, the hierarchical UI metamodel and process can produce systematic and layered UI models. This can improve the quality and reusability of models.

  • MDA(The Model Driven Architecture)는 모델을 기반으로 시스템을 개발하는 방법이다. 현재 MDA에서 제안하는 대표적인 모델링은 PIM, PSM으로 두 종류의 모델링 영역이 필요하지만, 적용 플랫폼에 따라 다양한 PSM이 필요하므로 모델링 영역이 확장된다. 또 MDA가 발전하면서 PIM과 PSM이 상대적인 개념임을 인식하면서 모델링 영역은 더욱 더 늘어날 예정이다. 다양한 모델은 다이어 그램으로 표현되고 이를 지원하기 위해 메타 편집 기능이 필요하다. 본 논문에서는 MBA 환경에 필요한 다양한 모델을 표현하기 위해 다이어그램을 생성하는 방법을 기술한다.

  • Record management metadata schema should have robust structure to represent not only elements innate in records itself but also management elements for the life cycle of records according to business activities. To realize these requirement, Information model for record domain is needed and also Metadata framework supporting semantic refinement and data element specialization required in record management business or applications are required. This study analyse main principles and characteristics of metadata scheme, and then suggested a novel method to develope schema systematically and effectively. This study propose information model and set of core data elements of records management based on ISO 15489 and 230381, and show how to implement the record management framework.

  • As business environment and complex work conditions are rapidly changing, large financial institutions are doing research on various fields to build a system that will efficiently and accurately process the production and modification of financial information and minimize the error in data-processing. In this paper, we have built a metadata system that, among various research areas, gives stability, accuracy and convenience in financial data modelling, analyze its effect and when adapting new models, provide mapping information from existing model to efficiently connect models and databases. If we manage modelling and standard data through this metadata system, the data standardization and database can process the model modification work in an unitary system and consistent high quality data model can be maintained and managed when data modification occurs.
