[show abstract][hide abstract] ABSTRACT: A formal definition of the semantics of a domain-specific language (DSL) is a
key prerequisite for the verification of the correctness of models specified
using such a DSL and of transformations applied to these models. For this
reason, we implemented a prototype of the semantics of a DSL for the
specification of systems consisting of concurrent, communicating objects. Using
this prototype, models specified in the DSL can be transformed to labeled
transition systems (LTS). This approach of transforming models to LTSs allows
us to apply existing tools for visualization and verification to models with
little or no further effort. The prototype is implemented using the ASF+SDF
Meta-Environment, an IDE for the algebraic specification language ASF+SDF,
which offers efficient execution of the transformation as well as the ability
to read models and produce LTSs without any additional pre or post processing.

Because textual representations of models also have their benefits, we investigated the integration of textual and graphical modelling languages, by comparing two approaches. One approach uses grammarware and the other uses modelware. As a case study, we implemented two versions of a textual alternative for Activity Diagrams, which is an example of a surface language. This paper describes our surface language, the two approaches, and the two implementations that follow these approaches.

[show abstract][hide abstract] ABSTRACT: We describe our experiences with the process of designing a domain-specific language (DSL) and corresponding model transformations. The simultaneous development of the language and the transformations has lead to an iterative evolution of the DSL. We identified four main influences on the evolution of our DSL: the problem domain, the target platforms, model quality, and model transformation quality. Our DSL is aimed at modeling the structure and behavior of distributed communicating systems. Simultaneously with the development of our DSL, we implemented three model transformations to different formalisms: one for simulation, one for execution, and one for verification. Transformations to each of these formalisms were implemented one at the time, while preserving the validity of the existing ones. The DSL and the formalisms for simulation, execution, and verification have different semantic characteristics. We also implemented a number of model transformations that bridge the semantic gaps between our DSL and each of the three formalisms. In this paper, we describe our development process and how the aforementioned influences have caused our DSL to evolve.
