We implement the RFID middleware system based on XML for large-scale data processing. The Implemented middleware system are consist of the reader interface for tag data collection, the event manager for a data filtering, and application interface for the RFID application. The implemented RFID middleware system is to support both a fixed type's reader and portable type's reader. we analyze the middleware function with four application accessing protocol, HTTP, XML, JMS, and SOAP, and demonstrate a filtering speed in terms of CPU utilization.

XML(Extensible Markup Language) is an emerging standard for data representation and exchange in e-commerce and internet-based information. However, to realize this potential, it is necessary to be able to extract structured data from XML documents and store it in a database, as well as to generate XML documents from data extracted from a database. Although many DBMS vendors are scrambling to extend their products to handle XML, there is a need for a lightweight, DBMS and platform-independent XML middleware as well. In this paper we describe such a XML2RDB middleware, that solves the following problems . generating relational schema from XML DTDs for storage of XML documents, importing data from XML documents into relational tables, creating XML documents according to a XMLQL(XML Query Language) from data extracted from a database.

Recently, use of Smartphones is growing at an extremely rapid pace. Many researchers have recognized the importance of developing Smartphones applications under these circumstances, and they have been conducted many studies to develop apps efficiently. The Smartphones middleware has become a focus of recent research to develop efficient Smartphones apps on a server-client environment in particular. In this study, for enhancing portability, expandability and convenience in the development of apps on the various platforms of Smartphones, We have proposed XML based Open API optimized in the Smartphones middleware. We also evaluated the performance, by applying it in Smartphone middleware environment.

The advance of computer, network, and Internet technology enables the control systems to process the massive data in the distributed computing environments. To implement and maintain the software in distributed environment, the component-based methodology is widely used. This paper proposes the middleware architecture for the distributed computer control system. With the proposed middleware services, it is relatively easy to maintain compatibility between products and to implement a portable control application. To achieve the compatibility between heterogeneous systems, the proposed architecture provides the communication protocols based on the XML with lightweight event-based service.

최근에 홈네트워크 분야에서 각 서비스의 특징에 따라 UPnP, HAVi, Jini등과 같은 다양한 홈네트워크 미들웨어들이 생겨나게 되었고 이들을 통합하기 위한 연구가 진행되고 있다. 대부분의 홈네트워크 미들웨어를 통합하려고 하는 연구들은 크게 두 가지의 문제점을 가지고 있다. 먼저 사용자가 가정 내에 홈네트워크 시스템을 구축하고자 할 때 그 비용이 사용자에게 너무 부담이 된다는 것이다. 또 다른 문제점은 시스템 구축 후에 새로운 홈네트워크 미들웨어가 추가될 때 이미 구축되어 있는 시스템과의 호환이 너무 어렵다는 것이다. 이런 문제점을 해결하기 위해 XML을 이용한 VHG 기반 메타컴퓨팅 미들웨어를 설계하였다. 이 홈네트워크 메타컴퓨팅 미들웨어를 XBI-Middleware(XML-based Integration Middleware)라 부른다. XBI-Middleware는 특정 홈네트워크 미들웨어를 사용하는 디바이스와 전혀 다른 홈네트워크 미들웨어 사용하는 디바이스 간에 정보 메시지의 전달을 위해서 프로토콜 변환에 용이한 XML을 사용하기 때문에 홈네트워크 미들웨어간의 정보 전달에 있어서 용이하고 추가적인 비용에 대한 부담감이 없다. 이 논문은 XML을 이용하여 다양한 홈네트워크 미들웨어를 통합하고 새로운 홈네트워크 미들웨어가 추가 되었을 경우 효율적으로 재통합 할 수 있는 방법을 제안한다.

Recently, RFID(Radio Frequency IDentification) has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles : companies have their own operating systems. while RFID is developed regardless of each campany's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system Middle assures that companies adopting RFID system for their logistic service are given athptabwebty to any systems whatsoever, avaweable by way of defining logistic information, tag information and reader information. For this purse, we implement as the basic web service a middleware system that turns all data into XML(eXtensatle Markupmsngunfo) of SOAP(Simple Object Access Protocol), the standard data.

Recently MPEG (Moving Picture Experts Group) has started a new standardization activity called MPEG Multimedia Middleware (M3W). The M3W supports multimedia applications Independent of hardware and software such as operating systems so that the portability and interoperability of multimedia applications are greatly improved. In doing so, the M3W adopts the concept of a service-based middleware. The M3W standardizes a set of multimedia Application Programming Interfaces (APIs) and their implementations can be pro vided by third parties In the form of services. In this paper, we introduce the usage of XML metadata in describing the standard multimedia APIs and third party's services and also we explain the role of the XML Schema within the M3W in providing transparent access from application to the M3W services.

The provision of personalized user interfaces for mobile devices is expected to be used for different devices with a wide variety of capabilities and interaction modalities. In this paper, we implemented a multimodal context-aware middleware incorporating XML-based languages such as XHTML, VoiceXML. SCXML uses parallel states to invoke both XHTML and VoiceXML contents as well as to gather composite multimodal inputs or synchronize inter-modalities through man-machine I/Os. We developed home networking service named "HomeN" based on our middleware framework. It demonstrates that users could maintain multimodal scenarios in a clear, concise and consistent manner under various user's interactions.

Recently, ebXML and Web Services are emerging as the XML-based electronic business frameworks. To provide a set of registry services which users or applications can store and search the business information, ebXML and Web Services use ebXML registry and UDDI registry, respectively. They use the different registries each other, but there are something that similiar to the structure and functions of both of registries. In this paper, we analyze the similarity of ebXML Registry Information Model(RIM) and UDDI data structure, and construct the mapping information. So, we design and implement the UDDI Service Middleware which translates the request of UDDI registry service into the request of ebXML registry service using the algorithm. Consequently, we could use the ebXML registry like ebXML registry as well as UDDI registry without any changes in the ebXML registry itself so that we can not need to have both of registries for e-business.

Because of different hardware specifications, there are no unified protocol commands to use with various kinds of RFID readers. The current commercial RFID middlewares do not satisfy the various requirements from users to support business process logic representation. The EPCglobal, which is leading organization for the RFID research, suggested a RFID middleware architecture which is called ALE(Application Level Events) standard. However, their architecture also does not provide the application level's interfaces. Therefore, a new RFID middleware architecture is required to provide basic RFID functions, conform to ALE's specification and, additionally, support application level's business logic representation. This paper proposes a ALE-based RFID middleware architecture which provides business process logic representation. At first, the basic RFID control functionalities are identified. Secondly, the business process logic requirements in RFID applications are identified and classified Into six categories. Third, the Middelware architecture is implemented with Java and XML technology so that it can easily extended to support the various RFID hardware's protocols. Finally, an example RFID prototype system is developed to show the proposed architecture's feasibility and validate it. The proposed middleware is expected to be used In various application areas since it is using XML technology for easy adaptation and it also con- forms to ALE interface which is standard specification.
