In article the approach to creation of the formal description of the metalanguage, used for development of visual domain-specific languages of information systems modeling, based on directed pseudo-metagraphs, is considered. Using graph models for formal metalanguage definition of system MetaLanguage allows to describe its properties, to develop algorithms of horizontal and vertical metamodels and models transformation.
The approach to information system development with domain specific languages is described. DSL-toolkit allows extending business process description languages by risks description tools.
Tools of the DSM-platform MetaLanguage for creation of domain specific languages and for multilevel modeling are described. The transformations definition facility provides lower labor consumption for languages development and for model transformations.
In paper the methods of model transformations created by means of visual modeling languages is considered. The detailed analysis has allowed to reveal existing problems in this area and to formulate approaches to their elimination.
