'Ubiquitous Computing' was appeared first time by Mark Weiser in 1988. Recently, as basic technologies for realization are offered and technical necessity is appeared, various researches are progressed about this. Various forms of technologies are needed to satisfy ubiquitous computing environment, such as home networking, telematics, industry automation and so on. Particularly, in the industry automation field that utilizes RFID technology, there have been many researches on the automation of supply chain management, control of goods in stock, physical distribution management, warehouse management, etc. We report about current research contents about RFID middleware framework which is necessary for RFID application development in ubiquitous environments. Then we analyze this and propose to RFID middleware framework's development direction that will be used in Ubiquitous Computing environment hereafter.
