Nowadays, XML has been favored by many companies internally and externally as a means of sharing and distributing data, due to its open-architectural structure. XML-GL, a graphical query language for document has the advantage of containing both structuring and defining of itself. By incorporating UML an XML document can become object-oriented and can be represented by graphical means. This paper proposes a XML-GL query modeling solution by using UML class diagrams. In order for the modeled objects to be properly restricted, the Object Constraint Language has been defined. This process converts XML documents into Object-Oriented data and combined with UML class diagrams, searches for XML documents can be increased.

The importance of EDI has been so emphasized that we need exchange/maintain electronic documents effectively, and convert them to other formats. The traditional EDI, however, is facing on the limitation of growth because of its high expense, and the closeness of information sharing. The EDIs of next generation, like open EDI, object-oriented EDI, and Internet EDI, have appeared to solve these problems. Finally, XML/EDI, which is very effective to solve these kinds of problems, is now replacing the traditional EDI and the HTML in Internet and, is influencing on e-Business. So, we are going to suggest a solution which uses XML/EDI as a substitute for the traditional one. First, we analyzed the problems of the traditional EDI system and organized the structure of XML/EDI system, Next, we developed the prototype of Internet bookstore to show the effectiveness and strength of XML/EDI over the traditional EDI.

Recently, by the interest of geographical information and the utilization field of geographical information diversifying. Various GIS(Geographic Information System) was built to manage geographical information efficiently. However, because of interoperability between geographic information system, OGC(Open Geospatial Consortium) standardized GML(Geography Markup Language) of the XML(eXtensible Markup Language) foundation in which an interoperability writes possible geographical information data. GML national standard is applied to various application fields at present, and the use is confirmed. In this paper, GML 3.2.1 encoding standard specification follows requirements of OGC recommendation, we designed GML document editing system using XML standard technology, and generated interoperability GML data.

◈ EDI ▶ 고비용이 요구되므로 주로 대기업에서 활용 ▶ 중소하청업체는 대기업 시스템에 통합된 모형 ◈ XML ▶ 전자 거래의 새로운 데이터 교환의 수단으로 등장 ▶ More open, more loosely-coupled more object- or component-oriented ▶ "EDI is dead"를 표방 ▶ 비즈니스 및 기술적 측면을 고려하지 알은 성급한 판단 ◈ EDI를 쉽게 포기하지 못하는 이유 ▶ EDI는 실제 비즈니스에 많이 이용되고 검증된 부분이 많음 ▶ EDI를 위한 그 동안의 많은 투자비용 ▶ XML을 이용한 비즈니스 메시지 설계 및 의미의 표준화가 이루어지지 않음(중략)

For efficient and precise searches in the Web environment, resources should be coded in a structured way. HTML does not cover semantic structure because of its fixed tagging. XML, which has emerged as an alternative standard markuplanguage, uses custom tags that allow structural searching. Therefore, this study aims to compare XML with HTML in terms of their characteristics and retrieval functions. In order to test retrieval functions of XML- and HTML-based systems, we constructed an experimental XML-based system. The XML-based system has several advantages over the HTML system. However, some improvements are needed to make the XML system more comprehensive and effective. First, XML document search engines with user-friendly interfaces are needed. Second, popular Web browsers such as Explorer and Communicator need to support XML 1.0 specification completely. Third, Open DTD format, which will allow information retrieval systems to retrieve documents and compress them into one single format, is also needed to control Web documents more efficiently.

Since XML (eXtensible Markup Language) was highlighted as an information interchange format, there is an increasing demand for incorporating XML with databases. Most of the approaches are focused on RDB (Relational Databases) because of legacy systems. But these approaches depend on the database system. Countless researches are being focused on DTD (Document Type Definition). However XML Schema is more comprehensive and efficient in many perspectives. We propose a meta-model for XML Schema that is independent of the database. There are three processes to build our meta-model: DOM (Document Object Model) tree analysis, object modeling and storing object into a fixed DB schema using model mapping approach. We propose four mapping rules for object modeling, which conform to the ODMG (Object Data Management Group) 3.0 standard. We expect that the model will be especially useful in building XML-based e-business applications.

e-book is digital contents using IT technology instead of paper. It is carried in Internet and displayed wish Viewer of PC, PDA or terminal. The Open eBook specification is to provide a specification for representing the content of electronic books to these viewers. The specification is based on HTML and XML, the same core languages that define the World Wide Web, and is designed to allow publishers and authors to deliver their material in a single format. In this paper, we design and implement the viewer that can support OEB(Open eBook) standard. Viewer is composed parser part and display part. In audition, we add some functions - the book shelf, the bookmark and the dictionary - for convenience of readers.

최근 지리 정보 시스템(GIS)이 전 국가적으로 대중화되면서 지리 정보가 다양한 분야와 다양한 서버 환경에서 사용되고 있다. 따라서, 이렇게 다양해진 지리 정보를 효율적으로 사용하기 위해선 지리 정보 시스템의 상호운용성은 필수적이다. 이를 지원하기 위해서 OGC(Open GIS Consortium)에서는 상호운용성에 대한 표준 명세인 OpenGIS(Open Geodata Interoperability Specification)를 제시하였으며, 또한 이를 웹 환경에서 검증하고 활용하기 위해 웹 매핑 테스트 베드에서 여러 가지 시도를 하고 있다 이러한 시도 중 하나로 웹 환경의 이질적인 지리 정보를 공통적으로 표현하기 위해 지리정보를 구조화된 문서인 XML(eXtensible markup Language)로 인코딩하는 GML(Geography Markup Language) 명세를 제시하였다. 본 논문에서는 다양한 환경에서 지리 정보를 표현하기 위한 GML 2.0 명세와 GML 2.0 에서 사용하고 있는 XML 스키마 명세를 분석하였다. 또한, 이를 토대로 사용자들이 GML 2.0 문서를 쉽게 생성, 디스플레이, 편집할 수 있도록 함은 물론 기존의 공간 데이타베이스 시스템의 지리 정보를 GML 2.0 문서로 변환하고, 반대로 GML 2.0 문서를 공간 데이타베이스로의 변환을 쉽게 할 수 있는 GML문서 관리 시스템을 설계 및 구현하였다.

The OpenGIS Consortium has proposed a new web-mapping technology to support interoperability in web GIS environment by developing the specifications of MapServer and GML. In this environment, the MapServer transforms legacy spatial data into GML data, and clients display them on standard web browsers. This web-mapping testbed proposes methods for discovering, accessing, integrating and displaying GIS information except processing of spatial operations which are essential services in GIS environment. This paper proposes the method for executing spatial operations on GML data which are overlays of different map layers in legacy data servers. To support spatial operations on GML data in web GIS environment, this paper designs and implements GDOM based on the W3C's DOM Specifications and OGC's Simple Features Specifications. This paper shows the specifications and implementation of GDOM and the process of spatial operations in web-mapping testbed environment.

The macro-parametric approach, which is a method of CAD model exchange, has recently been proposed. CAD models can be exchanged in the form of a macro file, which is a sequence of modeling commands. As an event-driven commands set, the standard macro file can transfer design intents such as parameters, features and constraints. Moreover it is suitable for the network environment because the standard macro commands are open, explicit, and the data size is small. This paper introduces the concept of the macro-parametric method and proposes its representation using XML technology. Representing the macro-parametric data using XML allows managing vast amount of dynamic contents, Web-enabled distributed applications, and inherent characteristic of structure and validation.
