RevRatio provides a tool for creating systematic reviews.
Revratio is a software package which assists a researcher in making a systematic review by providing an integrated and efficient user-friendly environment.
The goal was to create a powerful free (as defined by FSF) licenced under the General Public License. The software had to be scalable, portable and modular and created in Java.
RevRatio uses plugins both for searching online databases and for entering manual plugins. This means that just about any database or other reference can be used with RevRatio; if a suitable plugin doesn't exist, anybody with some Java programming skills can create one (see plugin development).
RevRatio was planned with multiuser environments in mind, but due to a very limited timeframe, this feature is not yet fully implemented. The missing features include authorization and synchronization. The multiuser requirement led to a server-client design that was implemented with RMI.
