  • This study proposed a method to redesign the search system by extracting the class, property, and code values of value domain from the key elements of the MDR system that conforms to the ISO/IEC 11179 standard. To implement this, an operating system conforming to the standard is required. Therefore, this study targeted the MDR system of the Korea Information and Communication Technology Association. As a result, it was confirmed that the redesigned MDR system can easily search and utilize specific metadata without understanding the conceptual domain, metadata element concept, metadata element, and value domain proposed in the standard.

  • Metadata standard is very important element to describe a digital resource in the records lifecycle. Metadata standard is influenced by the purpose and content of tasks that are performed to a resource. But it does not reflect a task-centric viewpoint to cover the whole records-lifecycle because metadata is defined and designed from a resource-centric viewpoint. In other words, to cover the whole records-lifecycle using metadata, it is necessary to properly select and combine metadata property from a task-centric viewpoint. Therefore, we proposed a task-centric metadata application profile that can combine and select appropriate metadata properties according to requirements and tasks performed on resource.

  • The metadata elements of TV programs were designed based on PBCore (Public Broadcasting Metadata Dictionary), which is useful descriptive metadata for TV programs, and on interview results with TV program records managers. TV program information was visualized to extract core information and build a proper schema. Through this analysis, detailed metadata elements were designed in four representative areas: intellectual content, intellectual property, instantiation and extensions.

  • Metadata is data about data that is used to mange data itself. As applications based on DBMS are increased, it is suggested that metadata model and metadata interchange model to manage metadata in DBMS. but metadata which is in the form of XML (eXtensible Markup Language) document is generally stored into RDBMS. Therefore In this paper, as for the method to store metadata of RDBMS into OODBMS, we design metadata model, metadata interchange model and implement new repository system. The metadata of RDBMS is translated into in the form of XML Document and integrated into XML Data Server on OODBMS, eXcelon and executes retrieval metadata information about RDBMS by XQL(XML Query Language). So It is possible to searchm edit a metadata. The metadata of XML documents stored in eXcelon is easily made to be printed in web browser by applying a XSL (extensible StyleSheets Language). So we can have a detail information about property of metadata in DBMS.

  • Cognitive and emotional product design is becoming crucial because the technology gap decreases more and more. Product design guidelines and the corresponding database are therefore needed to support sensing (e.g. sight, hearing, touch), cognition (e.g. attention, memory) and emotion (e.g. aesthetics, functionality) which users feel differently according to their genders and ages. The user property information which is extracted from various experiments can be used as critical criteria in product design and evaluation, and it is necessary to develop the integrated database of cognition and emotion where to store the user property information. In this research, we design the user property metadata for supporting cognitive and emotional product design and then develop a prototype system. The metadata is designed to reflect the classification of cognition and emotion by investigating and classifying the previous studies related to sensing, cognition and emotion. The user property information is designed in RDF (Resource Description Framework), and a prototype system is developed to store user property information of cognition and emotion based on the designed metadata.

  • To build the consistency among different metadata systems and to increase the interoperability of that systems even among different domains, naming rules and glossaries for the data elements are necessary. This study provides discussion of naming and identification of the data element concept, data element, conceptual domain, value domain, and its meta model. This study also describes example naming conventions based on ontology derived from the combination with object, properties, and representation of data elements. The naming principles and rules described in this study use I-R analysis, DC metadata set, and SHOE 1.0 as an example of the scientific documents. This study would be a guideline to build the naming rules of metadata based on ontology in various domains.

  • This paper suggests how to systemize administrative metadata required for managing intellectual property rights and their applications, which has been newly requested in digital library environment. For this purpose, firstly, the types of metadata required in digital libraries were identified. Secondly, this paper detected problems in MARC that digital libraries have been using as the tool for information organization. Finally, the structures of administrative metadata required by copyright laws were analyzed. On the basis of the researches above, this paper proposed how to systemize and operate administrative metadata that interlocks MARC, Dublin Core and administrative system of copyright trust agencies.

  • The preservation metadata which is defined the property and history of changes must be describes logically and structurally for implementing long-term digital preservation. The preservation metadata makes the users to access and retrieve authentic digital resources and the managers of digital archives to manage and preserve more effectively the digital resources. his paper is review of recent developments relating to digital preservation metadata including the taxonomy of information object classes of Reference Model of OAIS and outlines some library-based projects. Next, the paper investigates how to develop and use the preservation metadata in university libraries and what is the core preservation metadata elements. Finally, the paper recommends the set of preservation metadata elements with broad applicability to digital preservation in university libraries.

  • World Wide Web is not more meaningless sea of information but is becoming the Semantic Web that provides many users with meaningful information. The starting point is the XML and metadata, RDF is a stopover which gives technique to relate arbitrary web resources. And now, the semantic and logic of web resources can be settled in the Ontology. A lot of educational multimedia web resources in Korea have produced their metadata with KERIS's KEM(Korea Educational Metadata). Therefore our country have to start the study of the semantic and logic in web resources. But, many researchers in Korea are more eager to study Dublin Core's DC and SCORM's LOM metadata specification than KEM. Thus the study of method about sharing and integrating these three metadata specifications should be performed before the study of semantic and logic in web resources in Korea. We design the Ontology to integrate these three metadata specifications and implement the prototype system using this Ontology. These three metadata have some elements that have same labels and meanings, and other elements have different labels and same meanings. To match these different labels which have same meanings, we adapted the one-to-one mapping technique in designing our Ontology. This designed Ontology was imported as "integrated schema" in our prototype searching system to integrate three different metadata in databases. Moreover we know that the more specific property design of class in Ontology was needed in order to provide users with more informed searching results such as synonym, antonym, hierarchy and associations.

  • Nowadays, research data repositories (RDR) have become progressively widespread all over the world. To expand repository services and build up inbound linking strategy, organizations list their repositories with so called Global Registries. Accordingly, such registries should be carefully described by the related data. In this study, I explore the metadata schema of re3data.org. I collect and analyze descriptions from the listed repositories, and come up with some suggestions concerning possible improvements to the metadata schema. To accomplish this, I develop a crawler program, which collects necessary data from the re3data.org. Based on the analysis results, I have identified two issues that required elements is missing, one issue that required element value is missing when the corresponding property is applied, five inconsistency issues with re3data controlled vocabulary, six issues with undescribed optional elements, and two inconsistency issues between the elements and their attributes which do not pair with. I believe this discussion can facilitate improvements to the existing re3data.org schema and further help researchers who analyze data repository trends.
