Usually, design method to use UML by Object-Oriented Modelling is used much. But, generation of Metadata that use UML is not easy by difference of expression about detailed functions that Is Involved language and this in environment that differ. In this paper that solution method use XML Metadata Interchange Format(XMI) for standardization and normalization of Pattern and Class. And, for design of Metamodel select frequency A many 4 element of use among XMI Metamodel and create Metadata. Design DB repository for created Metadata storing and add pattern and Information about each class composition and use query and did so that reusability and extension of Metadata nay be easy.

With increasing amounts of information on the web and needs to access accurately them, it is very important to standardize metadata and to store and manage system. The RDF(Rdsource Description Framework) is a framework for representing exchanging, and reusing metadata. And, it can be processing uniformly the standardized metadata, because it uses XML(eXtensible Markup Language) syntax. The RDF schema provides a basic type system for use RDF models. In this paper, we propose rules and an algorithm to convert the RDF schema into an UML(Unified Modeling Language) class diagram and formal models to represent an object-oriented schema for the RDF schema. The proposed rules and algorithm are useful for natural mapping and the object modeling of RDF schema can be easily converted into the object-oriented schema, and the formal models supports an efficient environment for retrieving and processing object-oriented documents.

For increasing needs about web-based XML applications, there has been a lot of studies about WIDL, CDF and OSD that are related to XML. Especially, the OSD format describes software packages and their inter-dependencies that is widely used in a CDF file, IT uses different forms for representing relationships among software pakages, because there has not been proposed a method of object modeling about it until now. In this paper, we propose a modeling method for the OSD and CDF documents using UML relationships. It is a part of the project to merge XML, applications and convert thd OCD and CDF documents into an IML class diagram to generate OODB sheme. We can esily not only visualuze implementation and dependency relationships among software packages but also understand and transform logical structure of XML documents using modeling functions.

SOAP presents a protocol to realize efficient call of each components. It is based on XML and HTTP communications and existed on the network system. In this paper, An example of the system is given through XML web service and components which are consist of .net structure. We built a Knowledge Management System which shows various uses of components. A pattern is proposed to create objects though reuse of existing components.

최근 인터넷상에서 DTD 기반의 XML 문서가 문서의 교환의 목적으로 사용되어 B2B 상에서 XML 문서의 사용이 증가하고 있다. 그러나 DTD는 데이터 타입이 제한적이고 사용자가 원하는 형태를 정의하여 사용할 수 없기 때문에 좀더 유연하고, 재사용이 가능한 스키마를 B2B 상에서 표준으로 이용을 하게 되었다. 스키마는 객체 지향적이기 때문에 새로운 타입을 선언 시 기존의 데이터와 타입을 이용하여 확장 또는 제한을 하여 재사용성이 뛰어나다. 그러나 기존의 스키마 자동 생성기는 사용자가 바라는 최적화 코드가 아니고, 스키마의 장점인 모듈화가 전혀 되어 있지 않아, 재사용을 할 수가 없다. 따라서 본 논문에서는 기존 자동 생성기의 단점을 극복하여 문서를 XML 스키마로 변환할 때 모듈화가 되고, 재사용이 가능한 코드를 만들 수 있도록 자동 변환기를 설계하며, 기존의 변환기가 사용자 시점에서 사용하기가 어렵고, 복잡한 인터페이스를 가지고 있기 때문에 이를 사용하기 쉽게 단순화하고 DTB와 스키마를 다양한 외양으로 볼 수 있는 스타일(Style) 에디터를 첨가하여 변환기를 구성한다.

컴포넌트 소프트웨어의 주된 목적은 소프트웨어 개발에 있어서 재사용을 증가시키고 개발자간의 협동과 협조를 증가시키기 위한 것이다. 이러한 컴포넌트 기습이 가져야 할 가장 중요한 특징으로는 상호운용성이 있다. 이러한 상 운용성을 위해 분산 컴포넌트의 다양한 서비스들을 뵐 환경의 사용자들이 사용할 수 있게 하기 위해서, 웹 기반에서의 XML을 이용하였고, 현재 웹 기반의 환경에서 여러 가지 웹 기술들이 사용되고 있으므로, 이들 기술들을 사용하여 비교할 만한 가치가 있다. 따라서 본 논문에서는 분산 객체 패러다임중 하나인 CORBA의 컴포넌트들과 웹 환경의 사용자들의 상호운용성을 위해 CORBA와 XML의 연동을 위한 응용 웹 서버의 구조를 제안하고, 옹용 웹 서버 구조의 성능 분석을 한다.

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.

Software development creates many product that class components, Class Diagram, form, object, and design pattern. So this Paper suggests Index/XML Sequence Relation information system for product abstraction and classification, the system of design product Sequence Relation abstraction which can store, reuse design patterns in the meta modeling database with pattern Relation information. This is Index/XML Sequence Relation system which can easily change various relation information of product for product abstraction and classification. This system designed to extract and classify design pattern efficiently and then functional indexing, sequence base indexing for standard pattern, code indexing to change pattern into code and grouping by Index-ID code, and its role information can apply by structural extraction and design pattern indexing process. and it has managed various products, class item, diagram, forms, components and design pattern.

In this paper, we suggest a method for dynamic generation of SMIL documents by user profiles on the web. Generated multimedia documents are based on the SMIL (Synchronized Multimedia Integration Language) that are recommended by the W3C. The method generates automatically XSLT documents according to user profiles. SMIL documents are produced on real-time by integration of the XSLT documents and the XML documents that are made already. Most of conventional web-based documents are based on the HTML that is difficult to support reusability of documents are relation among multimedia abject. However, the suggested method is based on the XML, and so it supports reusability of documents and produces efficiently various SMIL-based multimedia documents. Application for the suggested method are as follows; Electronic commerce, tele-lecture, a web-based document editing, etc.

The UML(Unified Modeling Language) Class Diagram which is a part of structure of UML is fit for Object Modeling, and more recently, as the appearance of UXF(UML eXchange Format) UML Class Diagram by itself, can be exchanged in many other different system document. So this paper suggest the conversion system from UML Class Diagram to XML DTD. As this we can easily transformation and saving the UML Class Diagram that is the standard of Modeling Language to XML document which is so reusable. Also it can give a flexible method for the representation to the logical structure of document in various way because of converting XML DTD.
