Configuration Language for Domain Specific Modeling Tools and Its Implementation

The paper proposes an approach how to develop a configurator (tool) allowing defining a wide range of DSML tools. The configurator is based on the idea that DSML tool definition may be given by a universal metamodel (i.e., UML class diagram), and then it can be interpreted by a universal interpreter to obtain the working tool. But for non-standard cases when the existing metamodel facilities are limited, the extension point mechanism is introduced allowing adding a tool-specific functionality by specifically programming it. The developed configurator has been verified in several practical applications and has proven its effectiveness.
