The goal of next generation digital broadcasting is offering the interaction among consumers and providers as well as variety services. One of the important factors for this new broadcasting environment keeps the interoperability among providers and consumers since the environment is distributed. Therefore a standard metadata for digital broadcasting is required and TV-Anytime metadata is one of the metadata standards for digital broadcasting. The terminal nodes of TV-Anytime metadata are defined by using MPEG-7 metadata. MPEG-7 metadata is standard metadata for describing multimedia content. Therefore, if we use the MPEG-7 metadata for describing broadcasting content can offer multimedia search services like content-based search by the extension of metadata. The efficient management system for these metadata is important for offering the services with high Duality on real broadcasting environment TV-Anytime metadata and MPEG-7 metadata are technically defined using a single XML schema, so its instances are XML data. Currently, a lot of systemsfor managing XML data are proposed in many researchers and we can expect to adapt these systems for managing broadcasting metadata. But the methods used in these systems are not specific methods for managing broadcasting metadata because of methods for general-purpose. In this paper, we find the properties of broadcasting metadata and develop an efficient metadata management system that is based on the found properties. Since our systemis implemented on real broadcasting environment, we expect that the system is most efficient and suitable. Also our system is interoperable since we use XQuery as query language for querying broadcasting metadata.

XML(Extensible Markup Language) is an emerging standard for data representation and exchange in e-commerce and internet-based information. However, to realize this potential, it is necessary to be able to extract structured data from XML documents and store it in a database, as well as to generate XML documents from data extracted from a database. Although many DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS and platform-independent XML middleware as well. In this paper we describe such a XML2RDB middleware, that solves the following problems . generating relational schema from XML DTDs for storage of XML documents, importing data from XML documents into relational tables, creating XML documents according to a XMLQL(XML Query Language) from data extracted from a database.

As XML has become and emerging standard for information exchange on the World Wide Web it has gained attention in database communities of extract information from XML seen as a database model. Data in XML can be mapped to semistructured dta model based on edge-labeled graph and queries can be processed against it Here we propose new query optimization techniques using DTDs(Document Type Definitions) which have the schema information about XML data. Our techniques reduce traditional index techniques Also, as they preserve source database structure, they can process many kinds of complex queries. we implemented our techniques and provided preliminary performance results.

XML is becoming a de facto standard for exchanging data in Internet data processing environments due to the inherent characteristics such as hierarchical self-describing structures. Nowadays the number of 3D VE(Virtural Environment) available on the internet is constantly increasing, most of them focused low-level geometric data that lack any semantic information. VRML is composed of simple science graph. X3D is constructed based on XML and has many advantage. However, previous researches can not apply various advantage of XML. This work proposes an alternate approach for association semantic information to X3D VE based on XML. These information use navigation to VE. Moreover, we study extraction method of sematic information to XML document. In this work, we study saving techniques for navigation processing.

SOAP is a protocol used for information exchange in distributed computing environment and SOAP defines mechanisms for message transferring between distributed system and remote procedure call/response process. This SOAP is able to be used independently on hardware platforms and operating systems and program languages because it uses only a text-based XML for protocol. Therefore ebXML that is a standard for E-Commerce adopts SOAP for message exchange. In this paper, we implement XML Hub System using SOAP and apply on the system e-Procurement. By this XML Hub System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

POS system that become that is supply net administration and computerization fetters of customer management that become point in distribution network constructed database and use XML-Encryption that is certificate techniques of PKI and standard of security for security that is XML's shortcoming and design distributed processing POS system using XML for data integration by introduction of Ubiquitous concept. This POS system has four advantages. First, high portability Second, efficiency of data transmission. Third, improvement of data process speed. Fourth, security of data.

The purpose of this study is to develop the standards for construction documents. The standards will facilitate efficient exchange and sharing of construction documents among the participants such as owners, designers, constructors and other related parts throughout construction work process. For this reason, this study is intended to define the requirements for establishing XML-based electronic document standardization system, and to prepare the plan for developing XML electronic document in a consistent way.

본 논문은 XSD(XML Schema Definition)기반의 XML 문서를 웹, 엑셀 환경에서 다양한 관점으로 볼 수 있도록 템플릿 서비스를 제공하기 위한 시스템이다. 템플릿 서비스는 데이터스킨 서버에서 스킨을 통하여 서비스되며, XML 문서를 다양한 문서로 변환할 수 있도록 한다. 예로 XML 문서를 HTML로 변경하는 경우 XSLT(Extensible Style Language Transformation) 를 사용할 수 있고, 엑셀 문서로 변환할 경우 엑셀 템플릿을 만들어 스킨으로 제공할 수 있다. 스킨은 다양한 방법으로 구현될 수 있으며, XML 문서에서 사용자가 원하는 문서로 만들기 위한 미들웨어 역할을 한다. 사용자는 데이터스킨 변환 서버에 접속하여 가지고 있는 XML 정보들을 차트, 그래프, 수식 등으로 쉽게 변환할 수 있을 뿐만 아니라 OWC(Office Web Component)로 쉽고 빠르게 문서를 변환 할 수 있도록 한다.

Since e-Book has various advantages of hyper-link, multimedia function, dual-direction, etc, users can access to the system easily by touch method. XML has been established as the document standard of e-Book. For XML has hyperlink, style function, and structure it is suitable for knowledge delivery and expression. In this paper, we developed the Seoul's 1000 years time-capsule cultural contents into e-Book forms that can guide tourists. We also implemented the time capsule guidance system based on the e-Book of the user center through the modification process of the generated XML code using the e-Book solution.

Recently, Not only PC environment but also movile environment using XML for translating data. But the mobile delevopment is more limited but need highler security than PC environment Because there is some important service such as mobile banking. In this paper, We development the system to encrypt and decrypt the XML data in order to protect data, And the system is observing the recommendation of the XML Encryption Syntax and Processing by W3C. When encrypting the data, We use the entryption algorithm DES, Triple-DES, AES, SEED and RSA. and consideration of the mobile environment Last, We test the system at WIPI environment.
