ajoo is a framework for implementing DSML tools as web applications. The framework consists of DSML tool building platform and the DSML configuration tool. The platform allows implementing various kinds of DSMLs by reusing its components without programming them each time from scratch. The framework contains a configuration tool that provides means to specify DSML tools using graphical user interface to simplify and accelerate the DSML implementation process. Thus the framework's allows implementing a wide area of DSML tools without programming.
