In the field of maritime transport, various researches on next generation of standards are underway to realize e-navigation. While IHO leading the way, many studies on several S-100 based standards for exchange, sharing and utilizing maritime geographical information and related data are going on. IHO S-100 as a profile of ISO 19100 series of standards. Based on their application and service they provide, there can be different S-10x standards. In order to support the safe operation, various information should be integrated. When integrating a various information, it is crucial to make sure the same data model should be treated consistently and interpreted clearly across different profiles, such as S-101, S-102, etc. in this case. In this paper, I suggested a way to covert maritime metadata of S-100 to ontology so that we can perform consistent semantic analysis and processing of data in S-100 standards, which is the basis of other S-10x standards.

As open data(public data) began to be recognized as a source of national economic development, many countries began to build public data portals and provide open data to the private sector. In accordance with this trend, open source communities have begun to develop open data platform such as CKAN and enable to share dataset among open data platforms by applying metadata standard technology. However, many governments and local governments are still making it difficult to share data between data portals because they build their own platforms. In this paper, we propose a DCAT-based metadata transformation tool to solve these problems, and show how to transform a dataset into DCAT.

The purpose of this study is to present technical elements to improve the data utilization of the ISNI Korea Consortium, which is operated by the National Library of Korea, which is responsible for the registration of Korean names. The ISNI Korea Consortium aims to register various creation-related information in addition to bibliographic-related individual and organization name information. To this end, this study examines the ISNI Korea consortium, which is a data provider's consultative body, among other things, the metadata status of copyright organizations and the linked data specification of ISNI. As a result, data acquisition, refining, storage, identifier management, consortium metadata management, five in total, and RDF data management (repository) in terms of linked data, RDF data issuance, RDF data retrieval, RDF data inquiry, RDF data Eight technical elements, including download, ontology inquiry, standard term inquiry and mapping information management, were derived.

The usage increase of digital contents required solution for protection technology and interoperability of system. MPEG(Moving Picture Experts Group) proposed MPEG-21 Multimedia Frameworks. MPEG-21 IPMP is standard that provides the means to enable digital item and rights information to be persistently managed and protected across networks and devices. In this paper, MPEG-21 IPMP based system to protect digital contents designed by four structures of license server, production server, consumption server, tool server. License server create rights information document using the XML-based REL about multimedia contents of users. Production server makes a digital item by packaging multimedia resource and metadata, which is combined by REL information and IPMP information of multimedia resource. Consumption server takes care of the functions of players that use digital item, and tool server was implement to transmit for missing tool that might occur in all procedures.

As XML is used by standard format for information expression and information exchange in various field, Many Company began to use SVG by user interface or information expression tool of embedded system such as mobile phone based wireless internet. Because SVG has many additional information to keep structure of SVG document exception real data, there is a problem that transfer time of SVG file is so cost for quantity of transmitted data actually. To solve this problem, many researches using compression conception have been conducted for applying to an embedded system. This paper proposes SMETA that can use existing researches using compression concept at once. SMETA divides SVG file to each part that can allocate meaning, and gives semantic metadata to each part without alteration of SVG structure. SMETA can reduce site of transmitted SVG file actually by transmitting specification part of SVG file that metadata does not agree or has unlisted part in an embedded system between an embedded system and server, before transmit whole SVG file. By size of transmitting SVG file is decreasing, transfer time can be shortened accordingly.

In the era of big data, analyzing not only structured data but also unstructured data is emerging as an important task. Official documents produced by government agencies are also subject to big data analysis as large text-based unstructured data. From the perspective of internal work efficiency, knowledge management, records management, etc, it is necessary to analyze big data of public documents to derive useful implications. However, since many of the public documents currently held by public institutions are not in open format, a pre-processing process of extracting text from a bitstream is required for big data analysis. In addition, since contextual metadata is not sufficiently stored in the document file, separate efforts to secure metadata are required for high-quality analysis. In conclusion, the current official documents have a low level of machine readability, so big data analysis becomes expensive.

A need for sharing the R&D information at a national level regardless of the ministry in charge of it is being aroused. However, this information is being managed by different institutes under different ministries without a standard identifier which makes it difficult to manage the information such as to look up duplicate projects. A URN-based identifier is required for the integrated management and utilization of the national R&D information. In this paper, the concept of the identification metadata for applying the identification system and the status of the information management by each institute will be the subject for discussion. Based on this, the elements required for issuing a unique identification number and identifier to the national R&D projects will be suggested in this paper.

전자책에 대한 사회적인 관심과 다양한 장점에도 불구하고 현재 상이한 전자책 문서 포맷을 사용한 결과 전자책 컨텐츠에 대한 교환 및 공유를 어렵게 하여 결과적으로 전자책의 시장 활성화를 가로막는 가장 큰 장애가 되고 있다. 미국과 일본에서는 이미 관련 표준안을 제정한 바 있으며, 한국에서도 2001년 한국전자책 컨소시엄(EBH의 표준화 분과위원회를 통하여 전자책 산업 표준인 한국전자책문서표준(EBKS)을 제정하였다. 한국에서의 전자책 표준 EBKS는 HTML 및 PDF보다 다양한 장점을 제공하는 XML을 기반으로, 전자책 컨텐츠에 대한 정확한 교환 한국출판환경의 특징 반영, 생성 용이성, 관련 표준과의 호환성 제공 등을 기본 방향으로 한다. 한편 EBKS는 DTD 측면에서 고정된 문서구조, 확장메커니즘 제공, 세로 쓰기 다단 편집 그리고 한글 및 고어 특성 반영 등과 같은 특징을 포함하며, 스타일의 경우 교환을 위해서는 XSL-FO를 이용하여 컨텐츠와 스타일을 분리하고 있으며, 출력을 위해서는 XSL-FO를 권고한다. 그리고 EBKS 메타데이터는 사용의 용이성 교환 및 호환성 등을 제공하기 위하여 한정어(qualifier)를 사용하지 않는 dc-metadata와 확장을 위한 x-metadata로 구성된다. 한편 본 논문에서는 이러한 EBKS의 활용예로 XSL-FO를 이용한 전자책 컨텐츠에 대한 정교한 출력 결과를 제시한다.

Currently lots of studies to solve meta-data interoperability in between schema attributes are conducted. But the accuracy in previous schema mapping studies is low since the studies just use the similarity in between attributes. So the studies are not suitable for the schema mapping such as document conversion, system integration, etc. In this paper, we propose a method which can conduct the schema mapping interactively using frequent pattern mining. The method can conduct more accurate mapping process because the method use the description element which is an element among each schema element for the metadata standard. A performance study has been conducted to compare the accuracy performance of the method using metadata standards.
