  • Since traditional static metadata set like Dublin Core has static metadata attributes about bibliography information, integration of metadata for various metadata, problems about standard and extension of metadata must be considered for applying it to new environment. Specially, as event-driven metadata write method included the notion of e-commerce come out for interoperability in digital libraries, traditional metadata management which cannot distinguish between different kinds of update operations to new extension of metadata set occurs unsuitable waiting of update operation. So, improvement is needed about it. In this paper, we show whether alleviative transaction consistency can be applied to digital library or not. Also it would divide newer metadata into static metadata attribute connected in read operation within user read-only transaction and dynamic metadata attribute in update operation within dynamic(e-commerce) update transactions. We propose newer metadata management algorithm considered in classfication of metadata attributes and dynamic update transaction. Using two version for minimal maintenance cost and ARU(Appended Refresh Unit) for dynamic update transaction, to minimize conflict between read and write operations shows fast response time and high recency ratio. As a result of the performance evaluation, we show our algorithm is proved to be better than other algorithms in newer metadata environments.

  • The construction of preservation metadata is a prerequisite for the preservation of digital information. In the current approaches to digital archiving, however, there is no metadata structure optimized to describe preserved digital objects. This research proposed metadata packages that can support the description of digital objects from the perspective of the core processes of digital archiving. The proposed metadata packages consist of 4 wrapper elements and 25 sub-elements. They can provide detailed descriptions required to preserve digital objects in accordance with the core processes of digital archiving. Therefore, the proposed metadata package can be applied to digital archiving as a better approach to the description of digital objects compared to the approaches to information package.

  • Recently, NAND flash based storage devices are being used as a storage device in various fields through hiding the limitations of NAND flash memory and maximizing the advantages. In particular, those storage devices contain a software layer called Flash Translation Layer(FTL) to hide the "erase-before-write" characteristics of NAND flash memory. FTL includes the metadata for managing the data requested from host. That metadata is stored in internal memory because metadata is very frequently accessed data for processing the requests from host. Thus, if the power-loss occurs, all data in memory is lost. So metadata management scheme is necessary to store the metadata periodically and to load the metadata in the initialization step. Therefore we proposed the scheme which satisfies the core requirements for metadata management and efficient operation. And we verified the efficiency of proposed scheme by experiments.

  • This study aims to design the metadata elements for managing and maintaining digitized records resulting from digitization. The digitized records were first defined and characterized, then assigned as copies and surrogates for source records. Next, the factors to be considered when designing metadata elements for digitized records were determined by comparing standards from different countries like the United States and the United Kingdom. As a result of the comparison, establishing a relationship between digitized records and source records, expanding the automatically extracted metadata elements following resource characteristics, and creating metadata for digitization processes and projects were set to be the key tasks of metadata design for managing digitized records. Furthermore, the metadata elements for digital records and digitization processes were designed individually, and the elements to be added for each entity were proposed by referring to standards from other counties.

  • Data quality management is an important issue these days. Improve data quality by providing consistent metadata. This study presents algorithms that facilitate standard word dictionary management for consistent metadata management. Algorithms are presented to automate synonyms management of database metadata through web dictionary crawling. It also improves the accuracy of the data by resolving homonym distinction issues that may arise during the web dictionary crawling process. The algorithm proposed in this study increases the reliability of metadata data quality compared to the existing passive management. It can also reduce the time spent on registering and managing synonym data. Further research on the new data standardization partial automation model will need to be continued, with a detailed understanding of some of the automatable tasks in future data standardization activities.

  • Recently, many enterprises have attempted to construct data warehousing systems for decision-support. Data warehouse is an intelligent store of data that can aggregate vast amounts of information. Building DW requires two important development issues:(i) DW for the decision making of business users and (ii) metadata within it. Most DW development methodologies have not considered metadata development; it is necessary to adopt a DW development methodology which develops a DW and its metadata simultaneously. Metadata is a key to success of data warehousing system and is critical for implementing DW. That is, metadata is crucial documentation for a data warehousing system where users should be empowered to meet their own information needs; users need to know what data exists, what it represents, where it is located, and how to access it. Furthermore, metadata is used for extracting data and managing DW. However, metadata has failed because its management has been segregated from the DW development process. Metadata must be integrated with data warehousing systems. Without metadata, the decision support of DW is under the control of technical users. Therefore, integrating data warehouse with its metadata offers a new opportunity to create a more adaptive information system. Therefore, this paper proposes a DW development methodology from a metadata perspective. The proposed methodology consists of five phases: preparatory, requirement analysis, data warehouse (informational database) development, metastore development, and maintenance. To demonstrate the practical usefulness of the methodology, one case is illustrated

  • The new environment for records managements requires the revolutionary transition from paper-record management to electric-record management. Capturing contents, contexts, and structure informations of the electric records to preserve the evidentiality, authenticity, and reliability is the outstanding issue. The recordkeeping metadata has been placed at the center of the current issue. This study focused on the establishment of the structures of recordkeeping metadata for current and semi-current stages in the life cycle of records. The reason concentrated on current and semi-current stages is that the authenticity of the record is concerned as the evidence of the business processes. Current and semi-current stages are where the records is able to be produced, captured and managed in the business context. The metadata can be collected and preserved with authenticity. This study explained the relations between entities concerned with producing records and proposed the metadata elements by establishing data model.

  • The Dublin Core, MARC. IFLA-FRBR user communities are developing international standards for describing textual, physical and audiovisual resources to enable their resources discovery over the Internet. Therefore the metadata interoperability Problem has been exacerbated by the need for more complex metadata descriptions. In this paper we propose a new mechanism for metadata interoperability based on the new semantic web applications : IFLA-FRBR framework, INDECS metadata and an event-aware ABC models. This study introduces a new approach method which is essential to the generation of interoperable metadata descriptions, particularly in the context of multimedia contents.
