  • As increasingly diverse kinds of information materials are available on the Internet, it becomes a challenge to define an adequate level of metadata provision for each different type of material in the context of digital libraries. This study explores issues of metadata provision for a particular type of material, statistical tables. Statistical data always involves numbers and numeric values which should be interpreted with an understanding of underlying concepts and constructs. Because of the unique data characteristics, metadata in the statistical domain is essential not only for finding and discovering relevant data, but also for understanding and using the data found. However, in statistical metadata research, more emphasis has been put on the question of what metadata is necessary for processing the data and less on what metadata should be presented to users. In this study, a case study was conducted to gauge the status of metadata provision for statistical tables on the Internet. The websites of two federal statistical agencies in the United States were selected and a content analysis method was used for that purpose. The result showing insufficient and inconsistent provision of metadata demonstrate the need for more discussions on statistical metadata from the ordinary web users' perspective.

  • This paper describes difficulties for the producer's distribution and the user's acquisition of the spatial data because the circulation of them is complicated according to its kind in Korea. The way to overcome these difficulties would be to develop the clearing house system to incorporate GIS technology on Internet. This research proposes the problem statement, the architecture, and the operating environment of the system. The system contains the functions such as metadata generation, metadata registration, metadata version management, catalogue creation and update, reports generation, forms processing, metadata search, payments, GIS information pool, and spatial data browsing.

  • At present Content Management Systems (CMS) with various and diverse web contents have been in wide applications. But, for CMS of each enterprise has its own metadata which is very different from others, it causes the serious problem of web contents repetition. Also, it's a difficult technology to support protecting copyright of web contents which are in separated CMSs. Therefore, in this paper, we solved the problem of contents repetition through metadata integration between mutually heterogeneous CMSs. We also propose the technology of web contents authentication code for avoiding contents repetition and applying digital rights protection by supporting safe ship in vast quantity of contents.

  • Lately, most of the libraries subscribe electronic resources such as e-journals, under the license contracts for the access and use of these electronic resources. It was found that the management of licensed electronic resources in the library has become one of the major problems due to the lack of proper metadata elements in the existing management system of electronic resources. The purpose of the study is to establish metadata for licensed electronic resources.

  • In this study, we suggest the effective storage structure and management method for XML-based electrocardiography(ECG) data to support the interoperability between medical information systems, and implement the metadata system of ECG data providing the web-based information service. ECG matadata management system include functions for storing and managing as well as reporting PDF service of ECG data. We analyzed a characteristics of the data and access patterns for XML-based ECG and then used the non-partitioning storing method and indexing the extracted metadata from the HL7 aECC for supporting the quick search. We, using the template mechanism, converts the XML-based results data into various formats in order to provide services of the ECG reporting.

  • UCI(Universal Content Identifier), a digital content identifier is a identification system based on URN(Uniform Resource Name) for the transparent distribution, efficient search and management of digital contents. Digital contents given a UCI number need metadata for serving a exact contents that users need. However, the only metadata provided by UCI are deficient to represent various information of digital contents, and ontologies which could standardize and define explicitly semantic relations between metadata (provided by UCI) are needed for better representation of information and efficient search and management of digital contents. In this paper, we extended concept-relation between metadata with ontology and designed domain ontology enabling semantic-based search by expanding UCI meta data, and showed the more efficient search and management over the metadata by UCI through various queries.

  • Recently there has been a growing interest in the investigation and development of the next generation web - the Semantic Web. From the perspective of a information science, the next generation web - Semantic Web is a metadata initiative. It is reason that one of important stage of Semantic Web Construction is adding formal metadata that describes a Web resource's content and so people can find easy material using metadata. In this paper, 1 designed new application profile metadata architecture as a way to serve as interoperability between various open digital libraries using different information architecture in Semantic Web environment. Based on new application profile metadata architecture, 1 developed union metadata automatic generation and union search algorithm to integrate heterogeneous huge-scale metadata in the open digital library.

  • This study aims to develope a scholarly metadata information system based on conceptual elements of text structure of Korean studies research articles and to identify the applicability of text structure based metadata as compared with the existing similar system. For the study, we constructed a database(Korean Studies Metadata Database, KMD) with text structure based on metadata of Korean Studies journal articles selected from the Korea Citation Index(KCI). Then we verified differences between KCI system and KMD system through search results using same keywords. As a result, KMD system shows the search results which meet the users' intention of searching more efficiently in comparison with the KCI system. In other words, even if keyword combinations and conditional expressions of searching execution are same, KMD system can directly present the content of research purposes, research data, and spatial-temporal contexts of research et cetera as search results through the search procedure.

  • Rights process problem was stated among actors that participated in digital contents distribution while it was various type of digital content service. In order to solve it, It was expressed conceptual and technical elements by reflecting a system. Among them, the interoperability of metadata became a important issue. As for the metadata for contents service, necessity about standardization is stated as a basic framework composing a service system. This paper proposed the metadata element which focus on the rights process that is being a key factor of a DRM(Digital Right Management) system for digital comics contents service. Therefore, it was verified by using Context Model of MPEG-21 RDD with interoperability between metadata elements which developed a XML format and the existing MPEG-21 RDD elements. The study results will become basic materials in the system design that considered metadata element development and interoperability of digital contents of other field

  • Ubiquitous Sensor Network (USN) environments, sensors and sensor nodes, and coming from heterogeneous sensor networks consist of one another, the characteristics of each component are also very diverse. Thus the sensor and the sensor nodes to interoperability between metadata for a single definition, management is very important. For this, the standard language for modeling sensor SensorML (Sensor Model Language) has. In this paper, sensor devices, sensor nodes and sensor networks for information technology in the application stage XMDR-DAI -based metadata to define the USN. The proposed XMDR-DAI USN based store and retrieve metadata for a method for effectively agent technology. Metadata of the proposed sensor is based SensorML USN environment by maintaining interoperability 50-200 USN middleware or a metadata management system for managing metadata in applications can be utilized directly.
