This paper proposes an ontology population model based on ISO/IEC 11179. Much research has recently been done on harmonizing Web 2.0 and the Semantic Web, and the harmonization is defined as Web 3.0. The most important issues for realizing Web 3.0 include defining ontology schemas and populating instances for ontologies. To resolve the issue, Web ontology schemas should be precisely defined, and a method for populating Web ontology from Web resources should be developed. This paper proposes a Web ontology population model based on ISO/IEC 11179 - Metadata Registry (MDR), which is the international standard, developed to manage and use common standard concepts.

The ISO/IEC 11179 Metadata registry (MDR) is an international standard that was developed to register and share metadata. ISO/IEC 11179 represents an MDR as a metamodel that is an object model. However, it is difficult to develop an MDR based on ISO/IEC 11179 because the standard has no clear criteria to transform the metamodel into a database. In this paper, we suggest the design of an MDR data model that is based on object-relational transformation methodology (ORTM) for the MDR implementation. Hence, we classify the transformation methods of ORTM according to the corresponding relationships. After classification, we propose modeling rules by defining the standard use of the transformation. This paper builds the relational database tables as an implementation result of an MDR data model. Through experiments and evaluation, we verify the proposed modeling rules and evaluate the suitability of the created table structures. As the result, the proposed method shows that the table structures preserve classes and relationships of the standard metamodel well.

In various fields, ISO/IEC 11179-based MDR (Metadata Registry) systems have been developed. However, the current systems do not observe the standard, so inconsistency issue between metadata arises. Most of all, there exist several problems because ISO/IEC 11179 provides no standardized access method. SQL/MDR has been suggested to resolve those problems. SQL/MDR supports search operations, but it does not provide operations for vaild building and safe access for MDR. This paper, in the aforementioned issues, suggests MCL(Metadata Control Language) to guarantee safe and easy access control. MCL offers predefined roles and authority of user groups defined in ISO/IEC 11179 Part 6, and users are assigned to a proper user group. With such a way, MCL increases usability and security.

To construct machining databases, which are reusable and sharable their meanings, semantic metadata management is required. In this study a semantic data modeling process for machining data is developed. It combines conventional data models with ISO/IEC 11179 standard, metadata registry(MDR). Names of object classes and properties constituting data element names are identified using conventional data model while data elements are named and specified based on ISO/IEC 11179 in order to obtain semantic interoperability of data. An experimental application to electrical discharge machining(EDM) is performed to explain the process.

The Industrial Metadata Registry(IMR) for standardizing industrial information metadata was implemented and four drafts of metadata sets were developed based on the ISO/IEC 11179. The IMR consists of four individual metadata registries characterized by subject category. Accordingly, the system includes the integrated administration module, and the divisions administration module. The users of the system are divided into committee members and general users. The system has been developed with Oracle 9i and Java JSP over Linux operating system. The system will support the procedure for data sharing and exchanging among users and organizations and improve the availability and manageability of data and provide the standardization of data across the industry.

Until now, many metadata registries have been built in various fields and the metadata registries were built based on ISO/IEC 11179 which is the international standard for metadata management. However, their management systems do not fully support various and useful tools to easily and systematically manage the metadata registries. In this paper, we describe the metadata registry management system we designed and implemented. The implemented metadata registry management system provide many useful tools for efficient and easy metadata management. Finally, the developed system is also based on the international standard, ISO/IEC11179. Therefore, we can apply it to other fields for building and managing metadata registries.

This paper describes the major components of ISO/IEC 11179 metadata registry (MDR) standard designed to promote data interoperability between systems, explains and discusses semantic web technology and Web ontology languages initiated by W3C that can be employed to further enhance data interoperability, and finally proposes a framework for a new RDF/OWL-based MDR to convert from the current human-readable MDR to machine-readable MDR. If the new MDR is successful, we might be able to offer a better customized information service to users. The future research will be concerned with evaluating objectively the effectiveness of machine-readable MDR in meeting the needs of real users.

This study proposed a method to redesign the search system by extracting the class, property, and code values of value domain from the key elements of the MDR system that conforms to the ISO/IEC 11179 standard. To implement this, an operating system conforming to the standard is required. Therefore, this study targeted the MDR system of the Korea Information and Communication Technology Association. As a result, it was confirmed that the redesigned MDR system can easily search and utilize specific metadata without understanding the conceptual domain, metadata element concept, metadata element, and value domain proposed in the standard.

Standards for various multimedia and application fields have been developed, and the standardization for the multimedia and applications have been making as ISO/IEC 13249 packages by ISO/IEC JTC 1/SC 32/WG 4. This paper describes SQL/MM part 8, which is currently being standardized for providing consistent access support to metadata registries. Systems for ISO/IEC 11179 - metadata registries, the international standard, have been realized and utilized in various fields. However, there is no standardized query processing to share and exchange information between the systems, and thus it causes many problems. Therefore, SQL/MM part 8 described in this paper resolves these problems as well as makes users easily understand it.

메타데이터를 표준화된 형태로 저장하기 위해서 제안된 데이터 레지스트리(DR)는 메타데이터의 유통을 위한 구체적인 방안을 제시하고 있지 않으며, 현재 데이터 레지스트리는 HTML을 이용한 인터페이스만을 제공하고 있다. 본 연구에서는 데이터 레지스트리에 저장된 메타데이터를 효율적으로 유통할 수 있는 방법으로 XML을 이용하였으며, 이를 위해 ISO/IEC 11179에 기반한 데이터 레지스트리로부터 XML 문서를 생성할 수 있는 인터페이스를 설계 및 구현하였다. 구현한 XML 생성 인터페이스는 데이터 레지스트리에 저장된 메타데이터를 XML 형식으로 만들어 줌으로써, 응용 프로그램들이 효과적으로 데이터 레지스트리에 접근하여 메타데이터를 이용할 수 있는 환경을 제공한다.
