Currently RFID code systems are classified into ISO, EPC, uCode, KKR code, Mobile RFID code, and etc. According to RFID code systems, RFID system is changed. For various RFID code systems, it's difficult to make it to the network and permanence of RFID business. And the existing system isn't add new RFID code systems to RFID system, and change it efficiently. This paper is proposed to a system of Multi RFID code Identification Translation using Ontology. This system is able to identify code data from RFID reader using ontology build into the identifier info and translation info of RFID code systems, and translate to URN data. Therefore in case of extending and changing RFID code systems, we can add and change the identifier info and translation info of RFID code systems in ontology.

KISA announced KKR code system observing the international standard, ISO/IEC 15459, in order to activate the domestic RFID industry and improve mutual operation among RFID services. In this paper, we propose the way on code conversion based on ontology methods so as to effectively convert various types of RFID KKR code data collected from RFID reader into URN code in the middleware based on the ALE standard spec of EPC global. The results of experiment show that various types of RFID KKR code data could be converted into URN codes successfully. This means that even though new types of KKR code are added, it can be extended easily by adding ontology information without rebuilding the middleware.

The tracing system means that the system can follows, traces, and records every steps of production and delivery of goods and its ingredient. Specially, Koreans have big concern about food tracing system which is influential for health directly. We were more interested in medical herb using in oriental medicine than any other things. We proposed the process and design of tracing system for medical herb based on RFID(Radio Frequency IDentification) technology in this research. This study shows current medical herb tracing ways and RFID code system by using for world standard. Firstly, We designed the new process of traceability of medical herb with various preceding references based on RFID technology. Secondly we suggest that RFID code configuration using the international standard code(ISO code) and korean agricultural and marine products code for the proposed process. RFID code system is very important because this plays a means of identification for tracing about medical herb. The proposed code system have the elements as Issuing Agency Code, Issuer Number, inspection information, inheritance flag, area code, modified agricultural and marine products code, serial number in 96 Bit length. Lastly We defined the code-generation process in the tracing system.

The field of automatic identification using RF is the one of the emerging ubiquitous computing areas. Early RFID techniques was focused on hardware areas, but RFID middleware has recently gained a lot of attention, which collects and filters tag data, and provides it to enterprise applications. The RFID middleware proposed by EPCglobal only can process EPC tag data, and cannot handle the KKR code which is defined by korean organization. So in this paper, we propose a method which can process the KKR code in RFID middleware systems. Using our approach, the RFID middleware can be extended as general ubiquitous middleware systems which process not only EPC code but also KKR code.

RFID middleware is the system software that converts EPC data collected from RFID reader devices into meaningful data, that users want, and transfers the result to the users with a variety of protocols. ALE specification, the RFID middleware specification proposed by EPCglobal that is a leading group of do facto international standards with respect to RFID, can handle only EPC code. Meanwhile, a new code system which is called KKR was proposed by NIDA in order to represent RFID tag data in a specific manner and cultivate the domestic RFID industry. In this case, the existing RFID middleware can not process KKR code system because of inherent attributes of the system. In this paper, we proposed a method of KKR code conversion to properly process KKR code in ALE middieware, implemented our method in real, and adopted it into existing ALE middleware. Also, we proposed a new URN format for RFID tag data to manipulate KKR code in ALE middleware. By using the proposed method, the existing ALE middleware conforming to international specification can handle KKR code effectively, and the integration among RFID middleware and legacy systems can be easily supported also.

최근 들어 국방부는 RFID 기술을 기반으로 u-군수통합정보체계를 구축하기 위해 국방탄약관리 시스템 구축사업과 확산사업 그리고 F-l5K 자산관리 사업을 진행하였지만 국방 RFID 태그 코드의 표준화 부재로 임시방편적인 방법을 사용하고 있다. 따라서 국방 분야에서 어떠한 RFID 태그 코드사용이 바람직한지 영역의 표준과 경제성, 관리성, 확장성, 네트워크 환경, 정책적 사항, 그리고 미군의 활용사례 등에 관한 다양한 관점을 분석하여 코드를 선정하는데 도움이 되도록 하였다.

In this paper, u-FOS system is applied to field test in order to design the code structure based on standards and both 900MHz passive and 2.45GHz active RFID devices were used to test identification capacity in the field tests. For the stable RFID data obtainments, optimum speed of trucks and rail cars and most suitable tagging locations on them were resulted from field tests. The data obtained from ground logistics base and identified through the system is sent to u-FOS. Because the code structure is designed in the form of KKR code structure, this system can be implemented on RFID ODS network without difficulty. Therefore, we suggested the result as a guideline for corporations and government agencies to easily adopt the system.

The agro-livestock industry is composed of a complicated supply chain and the customer‘s interest in safety of agro-livestock products is increasing. In order to provide customer with the accurate information about the history of product, and make good use of these information, traceability systems based on RFID technology were implemented and are planned. It is, however, difficult to make the efficient flow of information and to enhance or expand the traceability system because of the lack of the standard of RFID code system. To overcome this problem, we propose a RFID code system for the traceability of argo-livestock products on the basis of ISO/IEC 15459 KKR code system.

EPCglobal TDT specifies standards on RFID tag representations and conversion rules among them. According to the rule, more than 200 combinations of code conversions are possible. In this paper, we propose a code generation scheme for developing TDT code conversion program, that imports TDT XML specification and generates conversion codes. The proposed scheme makes it easy to develop and to maintain the conversion codes.
