  • This study designed a suitable preservation metadata for archives of Korean traditional arts. To accomplish this task, we consulted OAIS reference model and PREMIS data dictionary, analyzed various preservation metadata. and surveyed resource characteristics of Korean traditional arts. We adopted elements with namespaces, honored original definitions and scopes by not violating principles of designing application profiles, and extended elements where necessary.

  • With the increasing of users' request about internet web service, importance of Internet datawarehouse to support decision making of users is increasing now. Early Internet datawarehouse was studied in the form of using existent database and XML. However, because of limitation of information expression ability, it is gradually changed to system that use metadata schema like RDFS. Because of distributed environment of the Internet, integration and saving of each metadata schemas into one global schema is important. However, between each different schema, semantic and structural conflicts can be happen in such situation and they must be controlled. In this paper, we analyze occasions of conflict when integrate distributed metadata schemas and propose conflict resolution technique for efficient internet datawarehouse query processing.

  • This study analyzed the current condition of authority control, introduced the MADS(Metadata Authority Description Schema) for authority data. MADS supports encoding an authority description for a agent(person, organization), event, term(topic, temporal entity, genre, geographic entity, hierarchical geographic entity, occupation) and defines main elements, subelements, and attributes using the XML schema language. Lastly, using the MADS's characteristics, this study proposed the effective use plans of interoperability of authority data.

  • Datawebhouse consists of both web log analysis used for customer management and datawarehouse used for decision support. However, datawebhouse needs complex operations for management in order to transform and integrate data from heterogeneous data sources and distributed systems. We propose a metadata schema in order to enable data integration and data management which are essential in datawebhouse environments. We show that our proposed schema supports datawebhouse development and enables integrated asset management of business information. With ETL metadata for web log extract, we can improve the data processing time of web log.

  • Currently lots of studies to solve meta-data interoperability in between schema attributes are conducted. But the accuracy in previous schema mapping studies is low since the studies just use the similarity in between attributes. So the studies are not suitable for the schema mapping such as document conversion, system integration, etc. In this paper, we propose a method which can conduct the schema mapping interactively using frequent pattern mining. The method can conduct more accurate mapping process because the method use the description element which is an element among each schema element for the metadata standard. A performance study has been conducted to compare the accuracy performance of the method using metadata standards.

  • In this paper, we design new video metadata schema for searching video segments to create UEC (User Edited Contents). The proposed video metadata schema employs hierarchically structured units of 'Title-Event-Place(Scene)-Shot', and defines the fields of the semantic information as structured form in each segment unit. Since this video metadata schema is defined by analyzing the structure of existing UECs and by experimenting the tagging and searching the video segment units for creating the UECs, it helps the users to search useful video segments for UEC easily than MPEG-7 MDS (Multimedia Description Scheme) which is a general purpose international standard for video metadata schema.

  • This paper proposes a new metadata schema for effective mobile service of augmented reality technology, which is used in the convergence of media into a frame among the real world image and objects of virtual world. The proposed metadata schema is extended from JPSearch Core Metadata Schema (ISO/IEC 24800-2 International Standard) with analysis of the functionalities under industrial requirements, and enables to provide an effective application in the actual services. In addition, the proposed schema is available to organize the exchange of information between heterogeneous systems. With development of the prototype system, the proposed metadata schema is going to be submitted and verified under ISO/IEC JTC1 SC29 WG1 JPEG AR standard project.

  • The necessity of the raw data management and reuse is issued by diffusion of the recognition that research data is a national asset. In this paper, a metadata design model by schema class inheritance and a metadata integrated search model by schema objects are suggested for a structural management of the data. A data architecture in which an schema object has an 1 : 1 relation to the data collection was designed. A suggested model was testified by creation of a virtual schema class and objects which inherit the schema class. It showed the possibility of implement systematically. A suggested model can be used to manage the data which are produced by government agencies because schema inheritance and integrated search model present way to overcome the weak points of the 'Top-dow Hierarchy model' which is being used to design the metadata schema.

  • The Metadata are used for the reuse of core information, distribution and management, protection of copyright and prevention of overlapping investment. Serious game consists of multi-hierarchial multimedia data. And quality information is very important for selection according to the purpose of the game. In this paper, we designed the serious game metadata schema, including multi-media characteristic information and measurable quality information. This study will lay the groundwork for the development of metadata system which can provide serious game users with reliability through quality information, and with compatibility through multi-media characteristic information. Furthermore, we hope this study will be helpful to stable growth in serious game industry.

  • TV-Anytime은 국제 표준으로 자리잡아가고 있는 차세대 디지털 방송용 메타데이터로서 사용자가 직접 원하는 방송을 검색하고 선택하여, 선택한 멀티미디어 데이터를 저장하였다가 시간과 장소에 구애받지 않고 사용할 수 있도록 하는 것을 목표로 하고 있다. TV-Anytime은 XML 스키마로 정의되어 있으며, 방송이라는 특성상 그 크기에 있어서 대용량이다. 본 연구에서는 이러한 TV-Anytime은 XML 스키마로 정의되어 있으며, 방송이라는 특성상 그 크기에 있어서 대용량이다. 본 연구에서는 이러한 TV-Anytime의 특성에 맞는 메타데이타 관리 시스템을 제안한다. 대용량의 문제를 해결하기 위하여 데이터베이스를 사용하며, TV-Anytime 스키마를 분석하여 그에 적합한 스키마를 설계한다. XML 형식의 TV-Anytime 메타데이타에 대한 질의를 위하여 XQuery를 사용한다. 이는 데이터베이스의 저장형식에 무관하게 질의하는 것을 가능하게 만들어 주며, 디지털방송 환경에서 시스템간의 상호 운용성이 확보될 수 있다. 또한, XQuery는 정보검색 기능을 가지고 있어서 향후 컨텐트 기반 정보검색을 포함하는 등 보다 풍부한 의미를 갖는 질의를 사용할 수 있을 것이다.
