XML encryption is to provide confidentiality service, though not limited to, for web contents. XML encryption can be applied to entire data files as opaque objects, or more frequently to various parts of XML documents, supporting various encryption granularity. It is this characteristic that makes XML encryption a more efficient alternative for data confidentiality in various web applications than is possible with SSL/TLS, IPsec, PGP, or S/MIME. It is essential for successful deployment of XML encryption to achieve interoperability among the products implementing this technology, which requires the products to implement the XML encryption standards correctly. Conformance testing is to test if products implement the relevant standard correctly. In this paper we present a conformance testing method for XML encryption products and implement it. We will first look at XML encryption standards developed by W3C, and extract test criteria. Then we propose a testing method in which the encryption capability and the decryption capability of a product are tested separately. The proposed methody is actually implemented as a GUI-based testing tool and some test results are presented.

Web services (WS) present a new promising software technology, which provides application-to-application interaction. They are built on the top of existing web protocol and based on open XML standards. Web services are described using WSDL, and the UDDI is a integration directory provide registry of Web Services descriptions. WSDL provides information of Web Services but it is getting more and more important to know more than those provided by WSDL. From WSDL we can not get the information like usage of WS, performance of WS, complexity of WS, usability of WS with other web service. In this paper, we proposed a new method for Web Services so called Public Web Services Analyzer (PWSA). This technique is based on analyzing various public UDDI registries in order to get various kinds of statistics of web services. Those statistics will be used by both web services developers and consumers for finding them suitable services for their needs. PWSA guarantees that it can provide enough information to find right web services for both Web Services Consumers and Web Service Developers.

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.

It is difficult that we collect only target documents from the Innumerable Web documents. One of solution to the problem is that we select target documents on the Web site which services many documents of target domain. In this paper, we will propose an intelligent crawling method collecting needed documents based on URL pattern script defined by XML. Proposed crawling method will efficiently apply to the sites which service structuralized information of a piece with database. In this paper, we collected 50 thousand Web documents using our crawling method.

We introduce about XBRL, eXtensible Business Reporting Language, which is widely accepted as the international standard language for business financial reporting. XBRL is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It provides major benefits in the preparation, analysis and communication of business information. It offers cost savings, greater efficiency and improved accuracy and reliability to all those involved in supplying or using financial data. XBRL is a kind of XML application based on the open Internet technologies. We propose a framework for enterprise information supply chain using XBRL Web services. A Web service is defined as a software system based on XML and designed to support interoperable machine-to-machine interaction over a network by the W3C. Web services are frequently just application programming interfaces (API) that can be accessed over a network, such as the internet and executed on a remote system hosting the requested services. An XBRL Web service-based enterprise information supply chain enables for companies to implement seamless information supply chains from businesses to financial institutions, to supervisory authorities, and to other stake holders for real time information access. And thereby it is expected to contribute to the increase in the value of companies due to the enhanced visibility and transparency of accounting and management.

A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. These systems may then interact with the Web service in a manner prescribed by its definition, using XML based such as SOAP, WSDL, UDDI messages conveyed by Internet protocols. Especially, UDDI is the Web Services Registry enabling to register and search Web Services, that takes charge of providing infrastructure for Web Services. However, the existing UDDI has a few problems that searching process is very simple and it cannot provide information of Web Services quality and quality-based retrieval. Therefore, this study suggest the Web Services quality description model that evaluates the Web Services quality.

In this paper, we investigate a problem with an e-learning system for e-business environments and introduce the solving method of the problem. To be more accurate, existing Web-hosted and ASP (Application Service Provider)-oriented service model is difficult to cooperate and integrate among the different kinds of systems. So we have produced sharable and reusable learning object, they have extracted a principle from pedagogical designs for units of reuse. We call LIO (Learning Item Object). This modeling makes use of a constructing for XML Web Services. So to speak, units of reuse from pedagogical designs are test tutorial, resource, case example, simulation, problem, test, discovery and discussion and then map introduction, fact, try, quiz, test, link-more, tell-more LIO learning object. These typed LIOs are stored in metadata along with the information for a content location. Each one of LIOs is designed with components and exposed in an interface for XML Web services. These services are module applications, which are used a standard SOAP (Simple Object Access Protocol) and locate any computer over Internet and publish, find and bind to services. This guarantees the interoperation and integration of the different kinds of systems. As a result, the problem of e-learning systems for e-business environments was resolved and then the power of understanding about learning objects based on pedagogical design was increased for learner and instruction designers. And organizations of education hope for particular decreased costs in constructing e-learning systems.

This paper implemented system that run Canonical XML and SOAP messages algorithm. So, can change to more elaborate regular document. Thus, interoperable with other application that takes W3C recommendation. Also, use in several system that physical identify is required when it exchange XML and SOAP messages for web service interoperability. Moreover, Adding the transformation ability between universal encoding scheme and EUC-KR that is internal encoding scheme should be Canonical XML and SOAP messages algorithm that is suited to internal circumstances, and this should be a foundation technique of international interoperability confirmedness.

현재 ebXML로 대변되는 XML 기반의 e-비즈니스 프레임워크 표준에 대한 관심은 세계 최고 수준의 초고속 통신 인프라에 힘입어 그 어느 때 보다 높은 상황이다. 이는 ebXML이 기존의 비즈니스 형태를 획기적으로 변화시켜 비즈니스에 대한 공간 및 시간의 제약을 극복하고 최소의 비용으로 최대의 효율을 낼 수 있는 차세대 전자상거래 프레임워크로 기대되기 때문일 것이다. 국내의 각종 IT 분야에서 보안 요소가 부가적인 요구 사항이 아닌 핵심 개발 요소라는 인식이 확대되어 가는 과정에서 e-비즈니스 프레임워크의 보안에 대한 연구가 미진한 것은 균형있는 프레임워크 발전에 있어 걸림돌이 될 것이다. 본 논문에서는 ebXML 프레임워크 및 최근 급 부상하고 있는 차세대 비즈니스 프레임워크인 웹 서비스(Web Service)에 적용될 수 있는 XML 기반의 보안 기술을 분석하고 ebXML 프레임워크 내에서 수행 가능한 비즈니스 프로세스 모델을 선택go 구체적인 시나리오를 실행하므로서 각각의 XML 보안 기술이 어떻게 보안 요구를 만족하도록 구성될 수 있는지를 설계하였다.
