LEA xDSML

Language Engineering for Analyzable Executable DSMLs

LEA xDSML is a research project concerned with language engineering methods for executable modeling languages. It is carried out by the Business Informatics Group at TU Wien, Vienna, Austria, and funded by the Austrian Science Fund FWF. The project has started in July 2018 and will run for three years.


Context

LEA xDSML resides in the context of Model-Driven Engineering (MDE), which proposes the use of domain-specific modeling languages (DSMLs) to reduce the complexity associated with the development of complex software-intensive systems, as, for instance, found in the automation domain, production domain, and automotive domain.

DSMLs are increasingly being developed to continuously leverage the domain-specific expertise of the various stakeholders involved in the development of complex system. Thereby, the integration of domain-specific knowledge into DSMLs can significantly improve the productivity of the development process and the quality of the final system. However, the development of DSMLs has also been recognized as a challenging and significant software engineering task itself.


Challenges

In this project, we focus on the challenges associated with the development of executable DSMLs (xDSMLs) that support the modeling and analysis of complex system behaviors through model execution. In particular, we aim at overcoming the following three challenges:

  • The lack of foundations for formalizing xDSMLs in a way that allows for model-level analyses.
  • The high efforts associated with the development of domain-specific analysis tools for xDSMLs.
  • The lack of fault localization techniques for efficiently identifying faults in models defined with xDSMLs.

Aimed results

The aim of this project is to develop a novel engineering framework for xDSMLs that will provide (i) concepts, techniques and processes to formalize xDSMLs usable for model-level behavior analyses, (ii) automation techniques for efficiently developing domain-specific model analysis tools for xDSMLs, (iii) and fault localization mechanisms for xDSMLs that allow an efficient debugging of models.

The framework will be iteratively developed and evaluated. The methodology for evaluating the framework builds on case studies, experiments with our master students, and collaborative studies with international collaborators.

The results of the project will significantly ease the development of xDSMLs and accompanying model analysis tools, and thus lead to reduced development costs of xDSMLs and at the same time increased quality of systems developed with xDSMLs. This will present a major cornerstone in the model-based development of complex software-intensive systems.
