The importance of long-term preservation of various types of electronic records through dark archives is gradually increasing. However, the current dark archive does not have an optimized information package structure for long-term preservation of electronic records. In order to address these problems, this research proposed four element categories by re-organizing the OAIS reference model information package based on the core process of the dark archiving. The detailed descriptive items of each category consist of a total of 4 upper-level elements and 27 sub elements based on the OAIS reference model, ISO 23081, Records Management Metadata Standard, ISAD(G), ISAAR(CPF), ISDF, and ISDIAH. This structure can be used as a basis for constructing an information package optimized for dark archiving, and is expected to support the long-term preservation of electronic records more efficiently.

The proposed new UCI syntax is compatible with the existing identifier and defines fixed length in such cases as printable ID, bar code and QR code which may entail better usage of identifier itself. For the compatibility, the identifiable metadata "key" is used for the existing UCI identifier and "UCI" element of metadata is defined for the new UCI identifier. The new UCI identifier plays roles of the resolution service and representation, and the old UCI identifier plays a role of internal DB management. Also, the object code has two types, meaningless and meaningful. The meaningful object code type can be used according the content classification standards in various field as comics, games, advertisement etc. The standardization activities can be supported by the root agency of UCI.

This study is to represent the research trends of the resource organization in Korea through the analysis of 607 papers related with resource organization in 4,015 papers on journals of 6 library & information science societies from 1970 through 2010. The results of this study are as follows. The average yearly papers in the case of academic journals published 14.8 pieces. The year published the largest number of papers: 2005 and 2009. The order of the number of papers by the domain of resource organization: cataloging, classification, indexing and abstracting, metadata, subject analysis. And the research on basic principle or theory in the resource organization showed insufficient. The research on KDC classification, cataloging rule, metadata element has are usually presented for improvements. But most of the research is not empirical analysis or objective assessment but subjective judgments of the researchers.

With the continuous development of the Internet and digital, platforms are emerging to store large amounts of media data and provide customized services to individuals through online. Companies that provide these services recommend movies that suit their personal tastes to promote media consumption. Each company is doing a lot of research on various algorithms to recommend media that users prefer. Movies are divided into genres such as action, melodrama, horror, and drama, and the film's audio (music, sound effect, voice) is an important production element that makes up the film. In this research, based on movie trailers, we extract audio for each genre, check the commonalities of audio for each genre, distinguish movie genres through supervised learning of artificial intelligence, and propose a utilization method for generating metadata in the future.

The paper discusses the nature of Knowledge Organization Systems (KOSs) and shows how these can support digital library users. It demonstrates processes related to integration of KOS like the Dewey Decimal Classification, $22^{nd}$ edition (DDC22) in DSpace software (http://www.dspace.org/) for organizing and retrieving (browsing and searching) scholarly objects. An attempt has been made to use the DDC22 available in Bengali language and highlights the required mechanisms for system-level integration. It may help a repository administrator to build an IDR (Institutional Digital Repository) integrated with SKOS-enabled multilingual subject access systems for supporting subject descriptors based indexing (DC.Subject metadata element), structured navigation (browsing) and efficient searching.

Data dictionary is a collection of meta-data, which describes data produced and consumed while performing business processes. Data dictionary is an essential element for business process standardization and automation, and has a fundamental role in ERP application management and customization. Also, data dictionary facilitates B2B processes by enabling painless integration of business processes between various enterprises. We implemented data dictionary support in SEA＋, a component- based scalable ERP system developed in ETRI, and found out that it's a plausible feature of business information system. We discovered that data dictionary promotes semantic, not syntactic, data management, which can make it possible to leverage viability of the tool in the coming age of more meta-data oriented computing world. We envision that business data dictionary is a firm foundation of adapting business knowledge, applications and processes into the semantic web based enterprise infra-structure.

In the last few years, The Semantic Web has increased the interest in ontologies. Ontology is an essential component of the semantic web. Ontologies continue to change and evolve. We consider the management of versions in ontology. We study a set of changes based on domain changes, changes in conceptualization, metadata changes, and temporal dimension. In many cases, we want to be able to search in historical versions, query changes in versions, retrieve versions on the temporal dimension. In order to support an ontology query language that supports temporal operations, we consider temporal dimension includes transaction time and valid time. Ontology versioning brings about massive amount of versions to be stored and maintained. We present the storage policies that are storing all the versions, all the sequence of changed element, all the change sets, the aggregation of change sets periodically, and the aggregation of change sets using a criterion. We conduct a set of experiments to compare the performance of each storage policies. We present the experimental results for evaluating the performance of different storage policies from scheme 1 to scheme 5.

Given the lack of suitable quality evaluation standards for educational serious games (designed for both entertainment and instruction), we designed a development framework for evaluation standards of educational serious games and proceeded to develop standards in accordance with our proposed procedure. Our standards were designed to evaluate the quality of both technical and non-technical elements of educational serious game software products. We conducted a survey on the need for individual elements of the standard. Participants rated the need for each element on a five-point Likert scale. We then performed a reliability analysis of the survey results. Based on the survey results, we established a final standard for quality evaluation composed of 9 main elements and 31 sub-elements. The results of our research will contribute useful information to users as well as to the developers of educational serious games.

XML(eXtensible Markup Language), next generation internet standard language has the advantage of easy re-use and re-structure in other computing environment because it has the separate data, presentation and structure. In this paper, we implement the efficient retrieval system for the general user by limiting the XML documents on the multimedia learning contents for the virtual education system. The system design is based on SCO Metadata unit defined in SCORM as the proposed virtual education standard. Each XML documents has three indexes - keyword, element and attribute. Also, it makes possible to retrieve data without previous knowledge of the DTD by making the element retrieval screen structure for the user interface. And it gives the user various result screen formats such as XML and HTML by restructuring the retrieval result through XML-QL and XSL, respectively.
