*Result*: Compiler generator for creating MOF-compliant source code models
*Further Information*
*Instead of the source code level, improving and maintaining the program code is more efficient when performed on model level. Source code is used to create the program model if it is not available. The new source code is created after performing the necessary changes in the model. To a certain extent, CASE (Computer Aided Software Engineering) tools are supporting this kind of round-trip engineering process, but in those cases both model elements and accepted source codes are fixed, and modelers can not modify the modeling process. Authors were aiming to implement a development infrastructure which supports user initiated component generation. According to their concept, meta-compilers and metagenerators are employed to create components based on metalevel task descriptions. In the present article authors introduce the process of creating the model of the source code, and the automatic generation of the program component implementing the model creation.
