XML (extensible Markup Language) is selected and published as a representative standard of electronic documents by W3C (World Wide Web Consortium). The structured information can be created and also transferred in XML documents. By utilizing XML, you can express the meaningful information unit as a structure comparing existed file typed information. With structured information, you can also manage retrieve, and reposit documents. According to the above facts, in this paper, it is the purpose to design and implement XML documents repository system to reposit and retrieve using structured information of XML documents. As a model it was designed to be stored by element unit which is the basic unit of documents and was also designed to retrieve the stored XML information by structured unit. It was, especially, designed to manage and reposit the structure of various documents effectively through creating schema as to DTD(Document Type Definition) and instance.

XML will be used in lots of areas in the Web environment as a method of information exchange, We have to use dat'abases to manipulate lots of XML documents efficiently, When we use database to manipulate XML, not only type of database but also its interface is important We develop a system using relational database, object-oriented database and wrapper to store XML data, of which interfaces are XML-View, ODMG C++ binding, OQL and DOM, We discuss pros and cons of each method by the implementation of the system, and propose an efficient manipulation method of XNIL documents.

As wireless network was developed and Capability of Wireless Phone was increased, M-Commerce was activates In Wireless network environment. User Authentication and Security in E-Commerce Environment is very important, so Authentication Technology, such as WPKI and Hermes System, XML Digital Signature in Wire Network is studying. But if authentication systems was implemented heterogeneous, WPKI is difficult to implement the system, it's not interoperate with authentication system on wire internet, not support XML digital Signature. Hermes system also not interoperate with XML digital signature system. So our paper designed System that can interoperate among digital signature systems and XML document to apply XML digital signature technology on wire network to wireless network, and then implemented system that can XML digital signature to use Java Card.

The XML has been becoming a basis of the related application and industry standards with proliferation of electronic transactions on the web, and the standardization on XML Signature, which can be applied to the digital contents including XML objects from one or more sources, is in the progress through a joint effort of W3C(World Wide Web Consortium) and IETF(Internet Engineering Task Force). Along with this trend, the development of products implementing XML Signature has been growing, and the XML Signature products are required to implement the relevant standards correctly to guarantee the interoperability among different XML Signature products. In this paper, we propose a conformance testing method for testing the XML Signature products, which includes a testing procedure and test cases. The test cases were obtained through analysis of XML Signature standards. Finally we describe the design and uses of our XML Signature conformance testing tools which implements our testing method.

급변하는 기업환경에 적응하고 경쟁력을 강화하기 위하여 정보 통신기술을 활용하여 업무처리 시간 및 비용을 절감하고, 품질을 향상시키기 위한 대안으로 EDI 시스템이 출현하였으며, 그중 다양한 문서구조 표현이 가능한 XML을 활용한 XML/EDI 가 급속하게 확산되고 있다. EDI 시스템에서는 보안 서비스를 제공되고 있으며, 그 중 전자서명은 중요한 비중을 차지하고 있다. XML을 이용한 전자서명 기법이 W3C에서 제안되어 표준호가 진행되고 있으며 이는 EDI 시스템에서 유용하게 이용 가능한 기술이다. 본 논문에서는 XML 전자서명을 XML/EDI에 적용하여 시스템을 설계하였다.

In this paper, we will introduce a design of key recovery based on XML can be used in B2B environment. XML Digital Signature and XML Encryption that are defied recently as standards by W3C(World Wide Web Consortium) are deployed to sign/verify or encrypt/decrypt documents for electronic commerce and keys to store/load at/from key recovery server. The result of signature or encryption is always an XML document and all messages used in this key recovery system are also XML documents. It enables to adapt transparently this key recovery system to legacy XML applications and electronic commerce platforms based on XML. And its method for key recovery is key escrow. One of the characteristics of this key recovery is that one enterprise can recover keys of some documents for electronic commerce from external key recovery system in other enterprises related with them and also recover keys from owns.

XML is normalized text form that is designed to transmit structured document in web as that propose in W3C (World Wide Web Consortium) in 1996. Function that this can overcome HTML's limit that use in existing in Internet and user define new tag to HTML by way to solve SGML's complexity added. There is many efforts to use storing this XML document in RDBMS but to relation style DB because XML document is tree structure structurally data SQL and perfect disaster caused by things that is language to ask a question accomplish XQuery that so it is W3C's XML standard query appear. After store XML informations including space information to RDBMS in this paper, Spatial XQuery through converter that is Sqatial XQuery2SQL through Spatial operator, Spatial function SQL of by Sqatial XQuery2SQL conversion algorithm that draw information in RDBMS after change embody wish to.

VoiceXML is a standard dialog mark-up language for the neat generation voice applications. The current VoiceXML 1.0 specification is silent on who place outbound calls for push-based voice applications. The push-barred voice applications become very important in modern information systems such as CRM. In this paper, we design and implement an extended VoiceXML platform that supports both inbound and outbound voice information services. We also extend the VoiceXML DTD so as to be able to inbound/outbound fax based on Call Control Requirements of W3C.

This article is a study on methods of digitalization for older oriental books using XML (extensible Markup Language) proposed as a standard for Web documents by W3C in 1996. In this paper, to digitalize older books, 1 designed the XML DTD(Document Type Definition) for general older oriental books and input the texts of the older books on the basis of the XML DTD, examined the problems and limitations in light of the technical level these days, and established the model of the system for using XML files of older oriental books at a national level in the future.

XML은 W3C에서 제안된 웹 상에서 데이터를 표현하고 교환하는 표준이다. XML 문서를 관계형 데이터베이스나 객체지향 데이터베이스에 바로 저장하기에는 적합하지 못하기 때문에, XML문서에서 DTD를 이용하여 관계형 데이터베이스 스키마를 추출하고, 저장하는 방법에 대한 연구가 활발히 진행되고 있다. 그러나 DTD는 타입이 제한되어있고, 확장의 어려움이 있기 때문에 XML 스키마를 이용하여 DTD의 단점을 보완하고, 관계형 데이터 베이스 스키마를 추출하여 저장할 수 있게 되었다. 본 논문에서는 XML 스키마를 관계형 스키마로 변환하는 기법을 제안하고 구현 결과를 보인다. 제안된 방법은 XML 스키마를 이용하므로, 타입의 확장성 및 유연성 등을 제공할 수 있다.
