Design of a metamodel-based telecoms modelling language

Along with the evolution of computer technology, language oriented programming came out as a revolutionary progress which beyond the object-oriented programming. In current object-oriented programming, the general modeling language UML lacks of rich syntax and semantics in the specific domain. Developing and using domain specific language model in the progress of language oriented programming can solve this problem well. By constructing a executable model based on the MOF, defining an abstract syntax model and an concrete syntax model and extending semantics, this paper designs a telecommunication topology modelling language TML which based on the MOF metamodel .TML contains rich syntax, semantics and constraints which are telecommunication domain specific, and has the executable feature, thus it greatly simplifies the complexity of system modelling in domain and enhances the efficiency of software production.
