In this paper, we propose the time relation model among the media with the concept of time and space on hypermedia system. This model classifies time proceeding relations in the node and among media connected with the link which is extended to internal link (while a current node remains, a destination node of internal link proceeds) and external link(a current node is replaced by a destination node of external link). Using this model, hypermedia system for hypermedia presentation is designed and implemented. This hypermedia system provides editing tools and controllers to created and edit nodes with time relation information, link tool to construct associative relations among nodes and navigation tool to control context flows.

Problem of compatibility, contents protection, contents circulation etc. was caused between contents offerer and consumers by indiscreet rights technical development about digital contents. Therefore, MPEG-21 framework proposed the REL(Right Expression Language) based on XML(extensible Markup Language) by rights expression language for rights management. We designed and implemented of the REL document editing system that rights creation and edit are available efficiently about contents easily without comprehension of MPEG-21 framework and client system that present consumption method of REL document.

컴퓨터의 사용이 보편화되고, 정보화 사회로 발전해감에 따라 이 기종간의 문서 정보 교환 및 인터넷과 네트웍 인프라의 향상으로 인한 문서 처리량은 계속 증대되고 있다. 또한 문서의 표현 방법 및 문서량의 증대로 인해 사용자의 요구는 다양해져가고 있다. 기존의 웹(Web)에서 사용되고 있는 HTML(Hyper-Text Markup Language)은 고정된 태그를 사용해서, 사용자가 직접 논리적인 구조를 갖는 문서를 작성할 수 가 없었다. 이에 W3C에서는 XML을 발표하여, 사용자가 논리 구조를 가진 문서를 작성할 수 있도록 하였다. 이러한 XML 문서의 논리적인 구조를 표현하려면, XML 문서 안에 어떤 것을 담을 수 있는지에 대한 규칙들의 집합인 스키마(Schema)가 필요하다. 현재 여러 종류의 스키마가 사용되고 있으며, 이를 이용한 다양한 문서들이 사용되고 있다. 본 논문에서는 현재 가장 많이 사용되고 있는 스키마인 DTD를 보다 쉽게 작성할 수 있는 자바 기반의 스키마 편집기를 설계 및 구현하였다.

In the field of game design, scenarios are essential part. But general-purpose tools for production of game scenarios have not been developed yet. In order to solve these problems, we studied the difference between game scenarios and other scenarios and analyzed scenario UCC(User Created Contents) and created suitable forms of game scenarios. To make OSMU(One Source Multi Use) easier, we use XML-based format of game scenario. To verify the possibility for practical application of XML-based format, we wrote a game scenario with scenario editor that we made and applied it to scenario-based game 'FEEL Online'.

In this paper, we propose a time relation model among media with the concept of time and space under hypermedia environments. The model explains time relations of node proceedings among media by time and proceedings among media connected with link. Using this model, hypermedia system which constructs dynamic nodes with time proceeding is designed and implemented. And this hypermedia system provides editing tool and controllers to edit dynamic node information, link tool to construct associative relations among nodes and navigaton tool to do node movement freely, various time controls and node proceedings.

Problem of compatibility, contents protection, contents circulation etc. was caused between contents offerer and consumers by indiscreet rights technical development about digital contents. Therefore, MPEG-21 framework proposed the REL(Right Expression Language) based on XML(eXtensible Markup Language) by rights expression language for rights management. We designed and implemented of the REL document editing system that rights creation and edit are available efficiently about contents easily without comprehension of MPEG-21 framework and client system that present consumption method of REL document.

현재의 웹 검색은 단순히 키워드 매칭만을 수행하기 때문에 검색 결과가 사용자가 원하는 정보와는 의미적으로 상이한 결과들을 많이 포함하고 있다. 사용자가 원하는 정보와 의미적으로 정확히 일치하는 정보들을 추출하기 위해서는 웹 자원에 대한 정확한 의미 부여와 함께, 이를 파악하고 선택적으로 획득, 통합, 가공할 수 있는 온톨로지와 같은 시맨틱 웹 환경요소들이 필요하다. 웹 기술 표준화 단체인 W3C에서는 이와 같은 웹 자원에 대한 의미표현 기술로 OWL(Web Ontology Language)이라는 웹 온톨로지 표현 언어를 발표하였으나 아직 이를 효과적으로 저작, 편집할 수 있는 도구는 전무한 실정이다. 따라서 본 논문은 OWL을 기반으로 하여 온톨로지의 생성 및 편집을 효과적으로 제공할 수 있는 통합된 저작도구를 설계 및 구현하였다.

본 논문은 영상, 음성, 문자 정보를 포함한 대용량 멀티미디어 자료의 효율적인 검색을 위하여 진행되고 있는 MPEG-7 국제 표준화 활동의 동향에 대해서 알아 보며 국제표준 MPEG-7을 따르는 MPEG-7 Description Generator의 설계에 관하여 연구한다. 이 생성기는 크게 MPEG-7 DS 편집 모듈과 MPEG-7 Description 편집 모듈로 나뉘다. MPEG-7 Description Generator는 표준화 대상이 아닌 비표준 도구(non-normative tool)로서 세계적인 기업들이 경쟁적으로 개발 중에 있는 멀티미디어 응용 프로그램 중의 하나다. MPEG-7 은 현재 표준화가 진행 중이지만 MPEG-7 Metadata Generator를 개발함으로써 많은 수요가 예상되는 MPEG-7 표준안이 채택될 시점에 MPEG-7 관련 응용프로그램 시장에서 선점하고자 한다.

This paper presents the design and the implementation of a MissCW(Multi user Interactive System for Synchronous Collaborative Writing). The document model DMDA(Distributed Multimedia Document Architecture) of MissCW consists of the logical structure, presentation style object, and mark object. The windows. The collaborative editor of this system proposes a structure oriented editing mechanism to combine distrbuted objects into one document. The middleware SOM(Shared Object Manager) maintains shared objects consistently and helps application programs use objects efficiently. The infrastructure of this system is a hybrid structure of replicated and centralized architectures, that is to maintain shared objects consistently inside of SOM and to reduce the overhead of network traffic. The central part is a virtual node which corresponds to the Object Controller of SOMwith the SOT(Shared Objet Table).

The Grid system is an emerging computing infrastructure that will substitute for existing distributed systems. However end users have a difficulty in using the Grid because of its complicated usage, which is an inherent characteristic from the heterogeneous mechanism of the Grid. In this paper, we present the JCML(Job Control Markup Language) and its GUI-based editor, which not only provide users with ease of use, improved working environment, but assist users to execute their jobs efficiently The JCML is a job control language that improves the RSL of Globus, which defines global services in Grid. The JCML is designed to support flexibility among various Grid services using standard XML. And it makes use of a graph representation method, GXL(Graph eXchange Language), to specify detailed job properties and dependencies among jobs using nodes and edges. The JCML editor provides users with GUI-based interface. With the JCML editor, a complicated job order can be easily completed using very simple manipulations with a mouse, such as a drag-and-drop.
