XML은 메타언어로써 구조적인 문서를 생성할 수있게 하며 이러한 구조적인 문서는 내용 기반검색,질의등의 처리가 가능하다는 것이다. XML문서의 논리적 구조를 표현하는 방법은 사용자 정의 문서타입(DTD)과 XML Schema 의 두가지 방식이 있으며, XML Schema 는 사용자 정의문서타입(DTD)에 비해 다양한 데이터 타입, namespace, Open-ended 데이터 모델등을 지원하여 문서의 구조 정의를 훨씬 더 유연하고 명시적이게 하게 하는 장점이있다. 본 논문에서는 XML 문서 검색을 위해 XML Schemadp 기반하여 내용 검색과 구조 검색을 효율적으로 지원하는 인덱스 구조를 제안한다. 요소들의 정의에 따르면 계층관계를 표현하기위한 구조정보와 XML 문서 인스턴스에서 나타나는 각 요소들의 순서정보를 요소의 ID로 사용함으로써 임의의 요소를 효율적으로 접근할 수 있게 한다.

ebXML (Electronic Business using extensible Markup language), sponsored by UN/CEFACT and OASIS, is a modular suite of specifications that enables enterprises of any size and in any geographical location to conduct business over the Internet. Using ebXML, companies now have a standard method to exchange business messages, conduct trading relationships, communicate data In common terms and define and resistor business processes. It is the mission of ebXML that provides an open XML-based infrastructure enabling the global use of electronic business information in an interoperable, secure and consistent manner by all parties for creating a single e1ectronic electronic market. This paper briefly overviews the concept of core component, context, assembly rule and context rule. Then, It designs by standard specifications of ebXML core component commonly used in an industry and among industries, and assembles business messages by using XML schema. Therefore, it suggests the mechanism which effectively exchanges business messages among the trading partners. This paper designs core component by using only three business messages of retail industry : orders, dispatch report, sales report.

ebXML is a global electronic business standard that is sponsored by UN/CEFACT and OASIS. ebXML is an open XML-based infrastructure enabling the global use of electronic business information in an interoperable, secure and consistent manner by all parties. ebXML Registry provides a stable store where the business information submitted by partners is made persistent and a set of registry services that enable clients of the Registry to access them. These services are tied to the structures defined in ebXML Registry Information Model(ebRIM), so we need a way to process them according to underlying database systems. In this paper, we present the result of developing the ebXML Registry Server based on Relational Database Systems.

The advance of computer, network, and Internet technology enables the control systems to process the massive data in the distributed computing environments. To implement and maintain the software in distributed environment, the component-based methodology is widely used. This paper proposes the middleware architecture for the distributed computer control system. With the proposed middleware services, it is relatively easy to maintain compatibility between products and to implement a portable control application. To achieve the compatibility between heterogeneous systems, the proposed architecture provides the communication protocols based on the XML with lightweight event-based service.

As the increasing interest about geographical information, such researches and applied fields become wide. OGC(Open GIS Consortium) developed GML(Geography Markup Language) which is adopted XML(extensible Markup Language) in GIS field. In various applied field, GML is used and studied continuously. This paper try to find out the meaningful rules using Apriori algorithm from GML documents, one of the data mining techniques which is studied based on existing XML documents There are two ways to find out the rules. One is the way that find out the related rules as extracting the content in GML documents, the other find out the related rules based on used tags and attributes. This paper describes searching the rules through two ways and shows the system adopted two ways.

With the energy paradigm shift from supply side management to demand side management, many researches have been done on demand side resource management and demand response. At the same time, Obix, BacNet-WS and OPC-UA are popularly used in buildings and industry energy management system. However, it is not easy to interchange the data and information among the systems cause a variety of protocols are used in buildings and factories. Therefore, in this paper, we are proposing an open business platform not only to integrate and manage the demand resources using various protocols and standards, but also to allow to plug-ins a new business service on top of the platform.

Big data, an important element of the 4th industrial revolution, is actively opening public data in public institutions and local governments. In the public data portal, everyone can conveniently search for data and check related data, but only those in ICT-related fields are using public data. Although data held by public institutions is open to citizens, it is difficult for anyone to easily utilize public data to develop applications. In this paper, data provided in open API format from public data portals has XML and JSON formats. In this study, we are a method of modularizing public data in XML format into a part that can be easily developed by linking it to a GUI interface. Based on the necessary public data, we propose a way to easily develop mobile programs and promote the use of public data.

The proportion of attacks via office documents is increasing in recent incidents. Although the security of office applications has been strengthened gradually, the attacks through the office documents are still effective due to the sophisticated use of social engineering techniques and advanced attack techniques. In this paper, we propose a method for detecting malicious OOXML(Office Open XML) documents and a framework for detection. To do this, malicious files used in the attack and benign files were collected from the malicious code repository and the search engine. By analyzing the malicious code types of collected files, we identified six "suspicious object" elements that are meaningful in determining whether they are malicious in a document. In addition, we implemented an OOXML document-based malware detection framework based on the detection method to classify the collected files and found that 98.45% of malicious filesets were detected.

Q+-reader, an E-Book reader system for XML based contents is introduced. The system is developed for the embedded platform, called Q+, which targets for the digital home electronics systems. The system supports XML contents and CSS based styling as described in Open e-Book standard. The system renders the e-book contents for users, so the contents are secured for a proper use. This will found an essential part of business infra for electronic books with copyright protection. The system was developed in Java language to be used in various platforms, and has an open architecture to be reusable for other standards as well.
