MPEG-V(ISO/IEC 23005) standardizes normative sensory effects metadata and sensory devices command for adapting the sensory effects between the virtual world and the real world. MPEG-V(Virtual) standardization has been carried out by 3DG(Dimensional Graphics) ad-hoc group inside MPEG Working Group(ISO IEC JTC1/SC29/WG11). For the scent effect, one of the sensory effects within MPEG-V, we proposed an olfactory interaction model including electronic nose and scent display to the ad-hoc group. Recently, we proposed types and elements related to the electronic nose as a sensor defined in MPEG-V standard for olfactory interaction. At the 114th MPEG meeting, the types and elements were consequently reflected on MPEG-V CD(Committee Draft) 4th edition. In this paper, we implement an electronic nose system applicable to MPEG-V standard by using MPEG-V schema, encoder, and decoder in order to assess their adequacy.

Due to the Fourth Industrial Revolution, innovation in various technologies such as artificial intelligence (AI), big data (Big Data), and cloud (Cloud) is accelerating, and data is considered an important asset. With the innovation of these technologies, various efforts are being made to lead technological innovation in the field of defense science and technology. In Korea, the government also announced the "Defense Innovation 4.0 Plan," which consists of five key points and 16 tasks to foster advanced science and technology forces in March 2023. The plan also includes the establishment of a Condition-Based Maintenance system (CBM+) to improve the operability and availability of weapons systems and reduce defense costs. Condition Based Maintenance (CBM) aims to secure the reliability and availability of the weapon system and analyze changes in equipment's state information to identify them as signs of failure and defects, and CBM+ is a concept that adds Remaining Useful Life prediction technology to the existing CBM concept [1]. In order to establish a CBM+ system for the weapon system, sensors are installed and sensor data are required to obtain condition information of the weapon system. In this paper, we propose a sensor data metadata schema to efficiently and effectively manage sensor data collected from sensors installed in various weapons systems.

This study has developed standard metadata for intangible cultural heritages based on multiple entity model. By analyzing "Preservation and Promotion of Intangible Cultural Heritage Act", which was newly legislated in 2016, intangible cultural heritages archiving books, archival information resources and guidelines of organizations which conducted resources investigations, the transmission status of intangible cultural heritages, and the current status of intangible cultural heritage digital archiving and information services of related organizations, we obtained information lists required for intangible cultural heritages and took them into account in the process of selecting elements for intangible cultural heritage metadata. In addition, developing the intangible cultural heritage metadata based on the multiple entity model made it possible to provide comprehensive information by organically linking numerous sorts of information-with intangible cultural heritage information, which is the most essential, in the center, information on agents related to intangible cultural heritages, archival information resources information that they produce, and record management task information required to manage these archival information resources. By maintaining various relations of intangible cultural heritages and keeping the information up-to-date, the developed metadata is expected to provide rich contextual information on intangible cultural heritages in addition to the efficient management of information; and ultimately, make contribution to sustainably developing the value of intangible cultural heritages.

We are faced with a paradox in the age of information as finding quality information on the Internet becomes a more challenging task because of information overload. This paper describes the prototype for “IPL-Korea” (Internet Public Library in Korea) project which is an attempt to provide the public with quality information in the form of a metadata system. The system involves cataloging of resources, i.e. websites, that are filtered by library and information science majors as well as information professionals. The user focus of this system is on children, youth, women, and seniors; various classification schemes and resource descriptions relevant for each user group are incorporated into the system to allow efficient browsing of the resources. A thesaurus for “IPL-Korea”, which is based on the ERIC thesaurus, is being constructed for easy manipulation of the breath of searching. The “IPL-Korea” metadata system employs the entity-relationship model in the design of its conceptual schema. Metadata is being stored in the Oracle database system and Web interfaces to this database are provided through ASP, ColdFusion, and JAVA technology.

As multimedia information recently increases fast, various types of retrieval of multimedia data are becoming issues of great importance. For the efficient multimedia data processing, semantics based retrieval techniques are required that can extract the meaning contents of multimedia data. Existing retrieval methods of multimedia data are annotation-based retrieval, feature-based retrieval and annotation and feature integration based retrieval. These systems take annotator a lot of efforts and time and we should perform complicated calculation for feature extraction. In addition. created data have shortcomings that we should go through static search that do not change. Also, user-friendly and semantic searching techniques are not supported. This paper proposes to develop S-MARS(Semantic Metadata-based Multimedia Annotation and Retrieval System) which can represent and extract multimedia data efficiently using MPEG-7. The system provides a graphical user interface for annotating, searching, and browsing multimedia data. It is implemented on the basis of the semantic metadata model to represent multimedia information. The semantic metadata about multimedia data is organized on the basis of multimedia description schema using XML schema that basically comply with the MPEG-7 standard. In conclusion. the proposed scheme can be easily implemented on any multimedia platforms supporting XML technology. It can be utilized to enable efficient semantic metadata sharing between systems, and it will contribute to improving the retrieval correctness and the user's satisfaction on embedding based multimedia retrieval algorithm method.

생물다양성은 육상 생태계, 해양과 기타 수생 생태계와 이들의 복합 생태계를 포함하는 모든 원천에서 발생한 생물체의 다양성을 알하며, 종내$\cdot$종간 및 생태계의 다양성을 포함한다. 지구상에 존재하는 생물이 매우 다양하듯이 생물다양성을 표현하는 데이터 또한 매우 다양하게 사용되고 있다. 본 논문에서는 먼저 생물다양성 데이터의 점보공유 및 교환을 위해 생물다양성 관련 국제기구에서 제안된 데이터 표준 및 데이터 교환 프로토콜을 알아보고, 이러한 데이터 표준과 프로토콜을 기반으로 국내 생물다양성 데이터 공유 및 교환을 위한 생물다양성 메타데이터 스키마를 크게 생물종 정보와 종정보에 관한 참조(reference) 정보로 나누어 설계하여 제시하고자 한다.

Currently, many companies are trying to be more competitive by implementing the most appropriate software package, called ERP (Enterprise Resource Planning). ERP can support the company's business process. A repository, which can store and retrieve enterprise-wide information, is a key component of such software package. This paper implements an enterprise repository for the ERP. A well-known repository standard, IRDS (Information Resource Dictionary System), is employed for the repository architecture. The proposed metadata schema can help develop database, business applications, models, and workflow. To illustrate the practical usefulness, a real-life ERP prototype is built within the framework of the proposed repository.

A framework for knowledge management system has been explored which enables the semantic search of knowledge on the web. Knowledge representation by RDF and RDF schema enables machine cognition of knowledge documents. Dublin core was adopted for structured metadata representation. Thereby, it enables the CBR and rule based reasoning for intelligent knowledge retrieval. Grafting of the WFMS technique unto the KMS facilitates the effective utilization of process knowledge and creation of new knowledge.
