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.

I designed the game UCI identification metadata to enable the game industry to provide copyright protection of game content, the efficiency of the management and distribution. This was mapped with existing UCI metadata which is composed of 9 elements that are applied to international standards for interoperability. I redefined 3 elements and added 3 more elements for reflecting the characteristics of the game. So it is composed of 12 elements in total. The result is verified by the general user survey and expert interviews. And I will develope the game UCI identification metadata management system with the results of study to be utilized by game agencies.

The quantity of business information like to be shared enterprise information and business catalog quickly increased because of activating e-commerce. Necessary of metadata management which is using RDF was required. RDF metadata management does not have to be restricted by RDF/RDFS knowledges, has to describe web resources and has to support metadata validation. But research which supports this is not enough. In this paper we enable to create and manage RDF/RDFS document using various interfaces, change from metadata to N-Triple and verify metadata validation.

Most metadata quality measurement employ simple techniques by counting error records. This study presents a new quantitative measurement of metadata quality using advanced weighting schemes in order to overcome the limitations of exiting measurement techniques. Entropy, user tasks, and usage statistics were used to calculate the weights. Integrated weights were presented by combining these weights and were applied to actual journal article metadata. Entropy weights were found to reflect the characteristics of the data itself. User tasks presented the required metadata elements to solve user's information need. Integrated weights showed balanced measures without being affected by the influence of error elements, This finding indicates the new method being suitable for quantitative measurement of metadata quality.

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.

This study is to investigate the problems in mapping between MARC data and Dublin core metadata, and to evaluate metadata as a source of cataloging. In addition resource description framework and its XML syntax for processing metadata in different format were analyzed in the view from encoding and transporting metadata in the network environments.

We propose semantic model that is possible to apply for the bibliographic metadata of domestic digital library by analysing bibliographic metadata models like MARC, DC, MODS, JeromeDL's metadata model MarcOnt as the representative case of semantic digital library and FRBR model as the conceptual model.

It is important to manage large amount of information from various information providers for supporting recent information services such as providing global research trends, detecting emerging signal and listing leading researchers. For integrated management, definition of integrated metadata schema, data transformation and schema matching are needed. It is first necessary to analyze existing various metadata for defining integrated metadata schema. In this paper, we have analyzed several metadata of scientific journal papers by classifying semantics, content rules and syntax, and looked around considerations to make integrated schema or transform metadata. We have known that XML is used as a syntax for supporting convenience and various usage condition, and hierarchy element names and common elements in semantics are needed. We also have looked at elements having various content rules and related standards. We hope that this study will be used as basic research material of metadata integrated management, data transform and schema matching for interoperability.

Recently, the semantic web stands out in the next generation web. To realize the semantic web, the metadata integration is required between different metadatas on the web for metadata management. Otherwise, the integrated structure is needed to accommodate all of semantic, syntax and structure. RDF is one of the core technology and is more efficient framework for technology and interchange of metadata in the web, In this paper, for metadata management, we designed and implemented the RDF authoring system which converts each of metadata into RDF and makes it easy to manipulate and manage the different metadatas. For this, we researched about the RDF creation using Dublin Core metadata, the conversion of XML document into RDF, the RDF expression by N-Triple form and the integration of WSDL and RDF, and implemented the system on the lava platform. Basically, users using this system can integrate and manage metadatas easily even if they are not expert.

YouTube videos of public institutions are digital public records that need to be managed and preserved. As such, the video and the metadata describing the video should also be preserved. This study aims to select the key metadata elements necessary for archiving videos published on YouTube by public institutions. To this end, five high-level areas, namely the description, structure, management, preservation, and user participation, and the metadata elements of 10 subareas, were designed by referring to NAK 8, PREMIS, ISAD(G), and YouTube metadata. Afterward, the metadata elements designed by 14 experts were verified. Lastly, the validity and reliability of the evaluation results were verified. Of the 63 elements, 33 satisfied the validity and reliability criteria. Thus, these elements were selected as the core metadata for archiving YouTube videos in public institutions.
