Contributions to Meta-Modeling Tools and Methods
Linköping University, Department of Computer and Information Science, PELAB - Programming Environment Laboratory. Linköping University, The Institute of Technology.
2005 (English)Licentiate thesis, comprehensive summary (Other academic)
Abstract [en]

Highly integrated domain-specific environments are essential for the efficient design of complex physical products. However, developing such design environments is today a resource-consuming error-prone process that is largely manual. Meta-modeling and meta-programming are the key to the efficient development of such environments.

The ultimate goal of our research is the development of a meta-modeling approach and its associated meta-prograrnming methods for the synthesis of model-driven product design environments that support modeling and simulation. Such environments include model-editors, compilers. debuggers and simulators. This thesis presents several contributions towards this vision, in the context of the Modelica framework.

Thus, we have first designed a meta-model for the object-oriented declarative modeling language Modelica, which faci litates the development of tools for analysis. checking, querying, documentation, transformation and management of Modelica models. We have used XML Schema for the representation of the meta-model. namely, ModelicaXML. Next, we have focused on the automatic composition. refactoring and transformation of Modelica models. We have extended the invasive composition environment COMPOST to handle Modelica models described using ModelicaXML.

The Modelica language semantics has already been specified in the Relational Meta-Language (RML). which is an executable meta-programming system based on the Natural Semantics formalism. Using such a meta-programming approach to manipulate ModelicaXML, it is possible to automatically synthesize a Modelica compiler. However. such a task is difficult without the support for debugging. To address this issue we have developed a debugging framework for RML, based on abstract syntax tree instrumentation in the RML compiler and support of efficient tools for complex data structures and proof-trees visualization.

Our contributions have been implemented within OpenModelica, an open-source Modelica framework. The evaluations performed using several case studies show the efficiency of our metamodeling tools and methods.

Abstract [en]

This paper presents the Modelica XML representation with some applications. ModelicaXML provides an Extensible Markup Language (XML) alternative representation of Modelica source code. The language was designed as a standard format for storage, analysis and exchange of models. ModelicaXML represents the structure of the Modelica language as XML trees, similar to Abstract Syntax Trees (AST) generated by a compiler when parsing Modelica source code. The ModelicaXML (DTD/XML-Schema) grammar that validates ModelicaXML documents is introduced. We reflect on the software-engineering analyses one can perform over ModelicaXML documents using standard and general XML tools and techniques. Furthermore we investigate how we can use more powerful markup languages, like the Resource Description Framework (RDF) and the Web Ontology Language (OWL), to express some of the Modelica language semantics.

Abstract [en]

This paper investigates how software composition and transformation can be applied to domain specific languages used today in modeling and simulation of physical systems. More specifically, we address the composition and transformation of the Modelica language. The composition targets the ModelicaXML dialect which is the XML representation of the Modelica language. By extending the COMPOST concrete composition layer with a component model for Modelica, we provide composition and transformation of Modelica. The design of our COMPOST extension is presented togheter with examples of composition programs for Modelica.

2004 (English)In: Proceedings of SIMS 2004 the 45th International Conference of Scandinavian Simulation Society / [ed] Brian Elmegaard, Jon Sporring, Kenny Erleben, Kim Sørensen, 2004, 405-412 p.Conference paper, Published paper (Refereed)
Abstract [en]

This paper presents recent work in the area of model-driven product development processes. The focus is on the integration of product design tools with modeling and simulation tools. The goal is to provide automatic generation of models from product specifications using a highly integrated set of tools. Also, we provide the designer with the possibility of selecting the best design choice, verified through (automatic) simulation of different implementation alternatives of the same product model. To have a flexible interaction among various tools of the framework an XML representation of the Modelica modeling language called ModelicaXML is used. For efficient search in a large base of simulation models the Modelica Database was designed.

2004 (English)Report (Other academic)
Abstract [en]

This paper presents the Modelica Standard Library, an ontology used in modeling and simulation of physical systems. The Modelica Standard Library is continuously developed in the Modelica community. We present parts of the Modelica Standard Library and show an example of its usage. Also, in this paper we focus on the comparison of Modelica, the language used to specify the Modelica Standard Library with other ontology languages developed in the Semantic Web community.

2005 (English)In: Proceedings of the sixth international symposium on Automated analysis-driven debugging. AADEBUG'05, New York, NY, USA: ACM , 2005, 77-82 p.Conference paper, Published paper (Refereed)
Abstract [en]

In this paper we present the design and usage of a debugging framework for the Relational Meta-Language (RML), which is a language for writing executable Natural Semantics specifications. The language is successfully used at our department for writing large specifications for a range of languages like Java, Modelica, Pascal, MiniML etc. The RML system previously had no debugging facilities, which made it hard for programmers to debug their specifications. With this work we address these issues by providing a debugging framework for debugging high level Natural Semantics specifications in RML.
