Subject: [gme-users] confused by semantic and syntax
>From Prof. Karsai's "Model-Integrated Development of Embedded
Software", I get the follows about DSML.
Formally, a modeling language is a five-tuple of concrete
syntax, abstract syntax, semantic domain, and semantic and
The concrete syntax defines the specific (textual or graphical)
notation used to express models, which may be graphical,
textual, or mixed.
The abstract syntax defines the concepts, relationships, and
integrity constraints available in the language.
The semantic domain is usually defined by means of some
mathematical formalism in terms of which the meaning of the
models is explained.
But, it is difficult to understand the "semantic domain". When
define a DSML, how to define its "semantic domain"? I confused
"semantic domain" with "syntax". Any one can illustrate me for
this? For example, an SF language. Or, is there any doc in
detail for this problem.
Any help is appreciated.
