This paper intends to suggest a XML-based secure E-Procurement system using Unified Modeling Language(UML), as an application system for domestic automobile industry. Applying UML methodology, which is Component-based Development (CBD), we analyzed the workflow on procurement operation of automobile industry and implemented a prototype of efficient E-Procurement system for automobile industry, by developing XML/EDI and XML signature. Also, on this paper, object-oriented CBD is employed to minimize the risk of life cycle and reuse software as mentioned to limitation of information engineering methodology. It enables the interoperability with ERP (Enterprise Resource Planning) as corporate legacy system. This system proposes a solution to apply analysis and design of workflow, component development, interoperability with corporate information system, and XML signature for integrity and authentication of electronic documents in other system so far.

XLink is XML Linking Language that defines links between XML documents or XML elements. It uses XML syntax to create structures that can describe links similar to the simple unidirectional hyperlinks of HTML, as well as more sophisticated links. There exist several relationships between resources that linked by XLink. Without supports from XML Repository for these relationship management, there is a huge overhead related to the management of relationships during both application development and maintenance, since the relationships need to be hard-coded directly into the application program itself. In this paper, we propose an XLink supporting system in object repository. We describe the design and implementation of this system on top of XDOM(persistent DOMlink XML repository). To support XLink, our system offers referential relationship semantics, extended link and the expansion of DOM tree for XLink.

XBRL is an XML-based language, actively used for diverse business reporting applications including financial reporting. It can be flexibly applied to each application by defining concepts and their relationships existing within the application. In these business reporting processes, it is very important for senders and receivers to validate the consistency and completeness of reporting contents in the syntatic and semantic levels. The basic method is to directly represent and validate the semantic constraints using application program codes. However, the method makes it difficult to represent, change, share semantic constraints. While XML constraint languages for XML documents such as XSLT and Schemantron support explicit representation and sharing of semantic constraints, they are limited in the efficiency and effectiveness of representing XBRL semantic constraints. This paper reviews XBRL formula, actively being discussed recently for standardization, and discusses the representation capability and limitations through a case analysis, which applies XBRL formula to business documents in the area of financial reporting.

As XML is more proliferate as a data type between internet programs, automatic generation methods of user input form interfaces get more attention. Recently, generating user interfaces for web application or web service clients become very popular. In this paper, we study the method of automatic generation for XForms-based user interface codes based on XML structure definitions in DTD. With the repetitive edit action model, we present a formal generation method of Input form codes and the overall user interface pages. For the generated code is using XForms as a target language, the result is clear and efficient with the MVC structure. Also, we have developed XFormsGen system which implements the proposed method over the Orbeon presentation server.

Compared with the desktop, the MIDP on J2ME has many limitations on memory capacity, screen size, networking ability and processing speed. In addition, screens vary with device providers in size, and service platforms vary with mobile service providers. These factors require additional functions to server and cause overheads of the server. On this paper, we propose the wav to reduce overheads of the server and to overcome disadvantages of the J2ME clients, with the server that provides the service of data in XML document type and the client on MIDP that is developed including the kXML parser.

Recently, in various fields XML has been become a standard for information exchange in internet. Therefore, the researches on data modeling for storing and fetching the XML documents have been made actively. However, existing researches have weak points that they can support neither versioning nor fast fetching of documents while changing documents in dynamic environments. In this paper, we propose four kinds of hybrid data modeling schemes that combine fragmentation model and nonfragmentation model. Our data modeling schemes are suitable to dynamic environments. We also present guidelines that our hybrid data modeling schemes can be used for various applications. We shaw through various experiments that our hybrid schemes partially outperforms the existing modeling schemes in terms of insertion time, storage space and retrieval time.

IMO developed e-navigation implementation plan which is a new paradigm of vessel safety navigation using harmonized information technology. S-100 standard for electronic navigational chart is also adopted as one of e-navigation strategies. In S-100 framework, not only geographic features of electronic chart but every safety related objects can be expressed by UML so that can be provided by web services. This paper research to test S-100 web service for casualty information. It is processed by modeling with UML, converting XML document by XML schema. Finally, the XML data is represented by web-based application.

다양한 응용 분야에서 점차 증가하고 있는 XML 문서를 효과적으로 저장하고 검색하는 방법에 대한 연구가 많이 이루어지고 있다. XML 문서의 정보를 데이터베이스에 저장하는 방법으로 분할 저장 방식과 비분할 저장 방식이 있는데, 본 논문에서는 두 가지 방법의 중간자적인 형태를 취함으로써 문서의 구조적인 정보를 효과적으로 표현하고, 검색 결과 재구성 시에 발생하는 오버헤드를 제거할 수 있는 시스템에 대해서 설명하도록 한다. 복잡한 계층 구조의 XML 문서를 서비스의 목적에 따라서 중요하다고 판단되는 단편노드의 단위로 구분하고 단편노드 안에 존재하는 세부 엘리먼트 및 속성에 대해서 별칭을 사용하는 검색 필드를 미리 구성해 놓음으로써, XML 문서의 구조적 특성을 명확하게 알지 못하거나 질의어 작성에 익숙하지 못한 사용자에게 보다 사용하기 편리한 XML 문서 검색 서비스를 제공할 수 있다.

대부분의 전자상거래 시스템이 유선 인터넷과 HTML(Hypertext Markup Language)을 기반으로 하고 있다. 그러나, 무선 단말기의 대량 보급으로 무선 인터넷이 인터넷의 새로운 패러다임을 주도하고 있으며, 효율적인 전자상거래를 위하여 HTML기반의 시스템이 XML(eXtended Markup Language) 기반으로 대치되는 과정에 있다. 무선 인터넷은 이동전화나 PDA(Personal Digital Assistant) 등 소형 무선 단말기 상에서 인터넷을 이용할 수 있도록 해주는 프로토콜의 총칭으로 정의되는 WAP(Wireless Application Protocol)과 같은 규약을 이용하여 다양한 서비스를 시간 및 공간의 제약을 받지 않고 무선 장치를 통하여 제공한다. 그리고, XML은 정보나 자료를 처리하는 데 있어 공통의 표준을 적용시킬 수 있고, 이 기종 응용프로그램간의 상호 작용을 중대시키고, 조직간에 정보 공유를 향상시킬 수 있다. 본 논문에서는 이러한 WAP과 XML의 장점을 결합한 전자상거래 시스템을 소개한다. 제안된 시스템은 WAP을 이용하여 무선뿐만 아니라 유선으로 실시간 정보 공유를 가능하게 하였고, 기존 시스템에서의 데이터베이스 시스템을 XML데이터로 대체시킴으로 인하여 데이터 저장을 위한 시공간의 비용을 절감시켰다. 뿐만 아니라 XML데이터의 사용으로 메타데이터를 생성 및 가공할 수 있는 방법을 구현하였다.
