The purpose of this study is to reveal the context within which EAD was developed, to review the elements and the structure of EAD 1.0 version and to introduce EAD as new standard for encoded archival finding aids in Korea. Encoded Archival Description(EAD) has been developed in 1993 in order to facilitate exchange of ISAD(G) descriptive information. EAD is currently administered and maintained jointly by the Society of American Archivists and the United States Library of Congress. While development was initiated in the United Stares, international interest and contribution are increasing. EAD is a encoding standard designed specifically for marking up information contained in archival finding aids. From its inception, EAD was based on SGML, and, with the release of EAD version 1.0 in 1998, it is also compliant with XML in order to facilitate easier internet access to SGML-encoded finding aids. EAD is the first tool to preserve the multilevel and hierarchical description manifest in finding aids by providing structures in which to describe entire record collections and increasingly smaller subcomponents thereof such as series, subseries, folders, and even items. Archival institutions can form a EAD consortium and also create a union database of EAD finding aids for the geographically dispersed collections. The EAD DTD provides a flexible way for archives to convert finding aids that exist in paper form into electronic documents or to create new finding aids in electronic form.

As XML is widely used, many researches on the XML storage and query processing have been done. But, previous works on path query processing have mainly focused on the storage and retrieval methods for a large XML document or XML documents had a same DTD. Those researches did not efficiently process partial match queries on the differently-structured document set. To resolve the problem, we suggested a new index structure using relational table. The method constructs the $B^+$-tree index using backward label paths instead of forward label paths used in previous researches for storing path information and allows for finding the label paths that match the partial match queries efficiently using it when process the queries.

Geo-features play a key role in object-oriented or feature-based geo-processing system. So the strategy for how-to-model and how-to-manage the geo-features builds the main architecture of the entire system and also supports the efficiency and functionality of the system. Unlike the conventional 2D geo-processing system, geo-features in 3B GIS have lots to be considered to model regarding the efficient manipulation and analysis and visualization. When the system is running on the Web, it should also be considered that how to leverage the level of detail and the level of automation of modeling in addition to the support for client side data interoperability. We built a set of 3D geo-features, and each geo-feature contains a set of aspatial data and 3D geo-primitives. The 3D geo-primitives contain the fundamental modeling data such as the height of building and the burial depth of gas pipeline. We separated the additional modeling data on the geometry and appearance of the model from the fundamental modeling data to make the table in database more concise and to allow the users more freedom to represent the geo-object. To get the users to build and exchange their own data, we devised a file format called VGFF 2.0 which stands for Virtual GIS File Format. It is to describe the three dimensional geo-information in XML(eXtensible Markup Language). The DTD(Document Type Definition) of VGFF 2.0 is parsed using the DOM(Document Object Model). We also developed the authoring tools for. users can make their own 3D geo-features and model and save the data to VGFF 2.0 format. We are now expecting the VGFF 2.0 evolve to the 3D version of SVG(Scalable Vector Graphics) especially for 3D GIS on the Web.

Electronic document processing using EDl (Electronic Data Interchange) must exchange documents using VAN (Value Added Network). However. the use of exclusive software needs alteration of a new document and the use of VAN(Value Added Network) demands an exchange of document and high cost for maintenance. Due to these problems, the existing EDI (Electronic Data Interchange) is turning into Web-based EDI (Electronic Data Interchange). This paper suggests techniques that change EDI (Electronic Data Interchange) messages which exist in two relational databases into XML (extensible Markeup Language) using the JDBC bridge. Also this paper proposes a method that recovers schema using converted XML (extensible Markeup Language) file, and a method which inserts an original record into a declared table. This solves the limitation of an original method that have to use sane database management system and also overcomes the problem in certain circumstances where the EDI (Electronic Data Interchange) exchange does not work.

For using XML data in programming languages, there is a data binding method, which generates classes from XML type definitions. However, since existing binding frameworks for this method generate all classes for element definitions, the number of generated classes becomes large and the complexity of the overall application system gets high. In this research, we propose an inline binding method for selecting necessary classes from element definitions. In the proposed method, classes are created only for elements with repetitions and recursions, and they include fields for values of terminal elements. We introduce a generation algorithm for binding classes and the marshaling methods for recovering the omitted paths. We develop IBinder system to validate the proposed method and compare the generated codes with the ones of existing systems. As a result, we carl show that the number of generated classes decrease substantially compared to other systems.

XML/EDI is different from traditional EDI because it offers the framework necessary for electronic commerce and extends the scope of the traditional EDI which focuses on data transfer. Since existing EDI services are moved to Internet platform and again to Web platform, users can use EDI in the integrated environment without inconvenience of using different EDI softwares, which have their own configurations. This paper describes the overall design and implementation of a Web-based XML/EDI system that is a core component for the electronic commerce. The constructed XML/EDI system in this paper is comprised of document generation module, document storage module, document search module, document management module, template document management module and e-mail transmission module. Requirements and design goal of XML/EDI system are introduced, detailed functionalities of modules and design facts are described and execution and execution procedures of the implemented system are explained.

Mobile codes such as Java, Java-Script, ActiveX, and Script code are loaded into a client system first and then run without any notice to the client user. Executing code by this mechanism may cause various security problems such as flowing out system information, deleting or modifying files, and exhausting system resources. In this paper we propose an integrated authentication system to establish the uniform security countermeasure on various mobile codes. The system helps to solve to problems mentioned above. An integrated authentication system allows to load into an interpreter using ACL (Access Control List) which sets up an access authority to the executable contents and communicates with an interpreter using client/server model.

In order to represent a play script using XML, a DTD has been defined and used on the web. However, it is not easy to make XML scripts using text editors for a writer who is not familiar with XML. Moreover, editors do not help actor/actresses use XML scripts for practicing plays. In this research, we develop a syntax-directed XML editor designed for writing XML scripts easily. Also, we implement a system that help actor/actresses practice plays together with multi-clients. Play events are synchronized by a time server synchronizing clocks of participants. We have evaluated the performance of various event implementation techniques through experiments and have used an appropriate technique for synchronizing play events. By using the system, a play writer can easily make an XML script and actor/actresses practice the play using the script.

Web is greatly contributing in providing a variety of information. Especially, as media for the purpose of development and education of human resources, the role of web is important. Furthermore, E-Learning through web plays an important role for each enterprise and an educational institution. Also, above all, fast and various searches are required in order to manage and search a great number of educational contents in web. Therefore, most of present information is composed in HTML, so there are lots of restrictions. As a solution to such restriction, XML a standard of Web document, and its various search functions is being extended and studied variously. Moreover, any technology, AJAX, and the old and new technology has two sides. The technology already exists, and it was not even considered before, because new technology is combined technologies. AJAX is a lot of Web 2.0 and Web technologies complement are combined. This paper proposes a search system able to search XML, AJAX in E-Learning or various contents of non-XML.
