The reason for this project was the absence of a free web-based tool for terminology management that would both allow storage and management of term entries with a comprehensive set of descriptive data and incorporate a forum style discussion service for lexicographers. The goal of this project was to develop a platform independent terminology management application that would use a web interface. The objectives were to investigate into the field of electronic tools for terminology management and electronic dictionaries, to distinguish the main features of such systems that could be used in creating a free and platform independent internet based terminology management system, to put into practice the principles of dictionary making and develop a web application that would meet the requirements of easy use and the ability to provide extensive descriptive information for terms. A set of requirements was drawn, the system was designed and a working application was successfully developed using Java technology. It runs on Apache Tomcat server and uses MySQL database for storage of term data. The system was presented with an initial set of 100 terms from the field of real-time systems.
