This paper presents a meta-tag expanded from scholarly service types of OpenURL written in Key/Encoded-Value format, after analyzing new scholarly service types and DataCite metadata elements which are for research data publishing and services. So far, OpenURL Z39.88 standard, KEVFormat: Sch-Svc, supporting six scholarly service type only, the expansion of this standard is needed for a research data circulation. New eight scholarly service types were extracted, after analyzing and comparing with the Scopus, Web of Science, and NDSL services. And nine representative attributes were extracted, after analyzing intensively the DataCite's elements.

양방향 데이터 방송 기술이 급속도로 발전하고 전세계적으로 표준화가 진행되고 있는 가운데 데이터 방송 콘텐츠에 대한 수요는 제자리를 맴돌고 있다. 이는 특화된 데이터 방송 콘텐츠에 대한 필요성을 의미하는 것으로 본 논문에서는 시나리오를 기반으로 기존 방송 콘텐츠를 활용하여 데이터 방송 부가 콘텐츠를 제작하는 모델안을 제안한다. 연구 모델은 1)시나리오 기반으로 기존 데이터 방송 콘텐츠 분석, 2)분석된 객체 아이템 메타데이터 스키마 설계 3)부가 콘텐츠 화면 구현의 단계로 구성한다. DMB 단말환경에서 가볍게 움직이는 콘텐츠 제작을 위해 메타데이터를 25개로 제한하고 이 안에서 Content Description, Shot Detection, Object Tracking로 메타데이터를 구분하여 스키마 다이어그램을 설계한다. 본 논문은 기존의 익숙한 콘텐츠를 재가공하여 제공함으로 DMB 수요 활성화 측면과 CP의 제작 비용감소 측면에서 긍정적인 영향을 끼칠 것으로 예상된다.

In the library domain, the metadata concerning the journal and the articles published in the respective journal are the important attributes that can be used to search academic related information. In order to conduct this study, the American JATS standard and the XML DTDs of journal articles commonly used by well-known publishers were used. By comparing JATS standard to XML DTDs used by Elsevier and Springer, we were able to extract a total of 50 metadata elements(10 about the journals, 7 about the issues, 22 about the articles, and 11 about the authors). Additionally, we identified a total of 7 mandatory elements, 9 applicable mandatory elements, and 34 optional metadata elements. The implication of this study is that we selected metadata elements using XML DTDs that are used in the real world.

One of the main issues in developing a digital library is how to implement an open digital library which can be interoperable, and diverse concepts, technology and protocols have been introduced to deal with this issue. In this study, it is analysed in terms of 'metadata interoperability', and based on the analysis, 5 basic component technologies are defined as follows: application profiles, modeling, implementation, resource discovery, portal service. Therefore it explains concepts of those core features, characteristics, cases in point, standardization and technical trends.

In this paper, we present a design and implementation of a personalized broadcasting system using TV-Anytime metadata for providing personalized services. The TV-Anytime specifies metadata schema, metadata coding and delivery, and provides service models to provide personalized broadcasting content services at anytime when users want to consume using metadata, which includes ECG (Electronic Content Guide) and content descriptive information in a PDR (Personal Digital Recorder)-centric environment. The proposed personalized broadcasting system consists of a server that provides metadata binary-coding, encapsulation and multiplexing, and a client terminal that takes charge of de-multiplexing, metadata decoding, and metadata processing for personalized content accessing and consumption. This paper presents the details of the design of each functional module, and the evaluation results with a set of service scenarios in an end-to-end broadcasting test-bed.

The standard metadata systems are very popular for the description of structures and semantics of information resources to realize sharing and exchanging information in global ubiquitous environment. In real application domain, various metadata elements are reused together with mix-and-match manner. An application system using diverse metadata systems is compelled with refinement and interoperability of metadata elements. Application profile is the general approach to resolve the various problems occurred in metadata application systems. This paper proposes Application Profile Core Ontology (APO) that can achieve the goals and functions of application profile, and describes metadata application system based on APO.

In this paper, we Propose a browsing system to reduce the contents retrieval time in the personalized broadcasting system. For this purpose, we add a subgenre table between Classification DS and Summarization DS of MPEG-7 MDS. The subgenre includes a subgenre list to shorten the searching time of contents which we want to find. In addition we divide metadata into event and object using Summarization DS of the MPEG-7 MDS. In this way, the hierarchical browsing of broadcasting contents is made possible. This structure may reduce the complexity of search by storing event and object separately. Our simulation results show that the search time of the proposed system is shorter than that of the previous works.

Nowadays, the demand of the output analyzed from the grid data have been sharply increased as the remote sensing technologies and GIS related industry have been developed. Therefore, a metadata access system which fits the requirements of the users should be developed for better managing and utilizing gridded data. In this background, this study defined a common application schema through the analysis of the metadata built by numerous institutes based on the draft metadata standards. The draft metadata standards has been proposed from the study supported by ETRI at 2003 which mainly concentrated on establishing the standards of distributing metadata for the grid data. Also, XML based integrated system was developed to access metadata maintained by SaTReC as well as SIMC to facilitate more convenient data access for the grid data users. The results of the pilot system developed from this study can be expected to contribute to build more efficient and enlarged integrated access system of metadata for grid data.

It has lately been recognized that the sharing and exchanging of the research results information is the critical factor to improve the research productivity. So many institutions are planning or developing the information systems which provide the research information services for researcher. But it has very difficulty in integrating the research resources information due to the dispersion and heterogeneity in data sources, and semantic and structural difference in describing data. We propose the semantic web based methodology and conceptual framework for raising the interoperability of metadata about research results information, which will support the integration of the distributed research data for information services in the end. We first introduce the ontology which is developed based on Standard Metadata of Research Results Information published by STISC. Then to show the applicability in real-world environment, we express the metadata of research information in RDF/RDFS according to ontology. Finally we proposed the conceptual architecture of research information service system which shows the main components, the functional requirements, and the principal and design direction at implementing the system.
