This paper presents our work on a visual programming environment (VPE) for portable, implementation-independent, virtual reality (VR) applications. Previously, we have defined InTml, the Interaction Techniques Markup Language , a domain specific language for VR applications, and some initial, command-line based development tools. By using the concept of Model Driven Development (MDD) and with the aid of tools from the Eclipse Graphical Modeling Project (GMF), we built an IDE for VR applications, that allows the visual description of components, application creation, and code generation to targeted runtime environments in C++, Java, and ActionScript. We report some advantages and shortcomings in this approach for tool development, some results from our preliminary user studies and lessons learned. In general, an MDD based approach to VPE is challenging both in terms of learning curve and usability of the final IDE.

Domain Specific Languages (DSL) are becoming increasingly more important with the emergence of Model-Driven paradigms. Most literature on DSLs is focused on describing particular languages, and there is still a lack of works that compare different approaches or carry out empirical studies regarding the construction or usage of DSLs. Several design choices must be made when building a DSL, but one important question is whether the DSL will be external or internal, since this affects the other aspects of the language. This chapter aims to provide developers confronting the internal-external dichotomy with guidance, through a comparison of the RubyTL and Gra2MoL model transformations languages, which have been built as an internal DSL and an external DSL, respectively. Both languages will first be introduced, and certain implementation issues will be discussed. The two languages will then be compared, and the advantages and disadvantages of each approach will be shown. Finally, some of the lessons learned will be presented.

The research about the formalization and conduction of controlled experiments in software engineering has reported important insights and guidelines for their organization. However, the computational support to formalize and execute controlled experiments still requires deeper investigation. In this context, this paper presents an empirical study that evaluates a domain-specific language (DSL) proposed to formalize controlled experiments in software engineering. The language is part of a model-driven approach that allows the generation of executable workflows for the experiment participants, according to the statistical design of the experiment. Our study involves the modeling of 16 software engineering experiments to analyze the completeness and expressiveness of the investigated DSL when specifying different controlled experiments. The results highlight several limitations of the DSL that affect the formalization and execution of experiments. These outcomes were used to extend and improve the evaluated DSL. Finally, the improved version of the language was used to model the same experiments in order to illustrate the benefits of the proposed improvements.

The complexity of creating artificial intelligence applications remains high. One of the factors that cause such complexity is the high qualification requirements for developers in the field of programming. Development complexity can be reduced by using methods and tools based on a paradigm known as End-user development. One of the problems that requires the application of the methods of this paradigm is the development of intelligent systems for supporting the search and troubleshooting onboard aircraft. Some tasks connected with this problem are identified, including the task of dynamic formation of task cards for troubleshooting in terms of forming a list of operations. This paper presents a solution to this problem based on some principles of End-user development: model-driven development, visual programming, and wizard form-filling. In particular, an extension of the Prototyping expert systems based on transformations technology, which implements the End-user development, is proposed in the context of the problem to be solved for Sukhoi Superjet aircraft. The main contribution of the work is as follows: expanded the main technology method by supporting event trees formalism (as a popular expert method for formalizing scenarios for the development of problem situations and their localization); created a domain-specific tool (namely, Extended event tree editor) for building standard and extended event trees, including for diagnostic tasks; developed a module for supporting transformations of XML-like event tree representation format for the knowledge base prototyping system – Personal knowledge base designer. A description of the proposed extension and the means of its implementation, as well as an illustrative example, are provided.

Представлена реализация модуля генерации параллельного программного кода на Charm++ в компиляторе проблемно-ориентированного языка программирования Green-Marl, предназначенного для разработки параллельных алгоритмов анализа статических графов. Приводится описание представления графа в генерируемом коде и способов отображения основных конструкций языка Green-Marl в параллельный код на Charm++. Проведенное оценочное тестирование с использованием типовых графовых задач (поиск кратчайших путей от заданной вершины до остальных вершин графа (SSSP), поиск связных компонент (CC) и вычисление рангов вершин с использованием алгоритма PageRank) показало, что производительность программ на Green-Marl, странслированных в Charm++, находится на одном уровне с реализациями на Charm++, разработанными вручную. The implementation of a code generation mechanism in the domain-specific language (DSL) Green-Marl compiler targeted in the Charm++ framework is presented. Green-Marl is used for the parallel static graph analysis and adopts an imperative shared memory programming model, whereas Charm++ implements a message-driven execution model. The graph representation in the generated Charm++ code and the translation of the basic Green-Marl constructs to Charm++ are described. The evaluation of the typical graph algorithms: Single-Source Shortest Path (SSSP), Connected Components (CC), and PageRank shows that the performance of Green-Marl programs translated to Charm++ is the same as for native Charm++ implementations.

Abstract - the article addresses the existing problems found in the area of Domain-Specific Languages (DSLs). Being a widely adopted programming technique, DSL grammar creation process still lacks desirable traceability and automation. The paper proposes a sequential model transformation process based on Model-Driven Architecture concepts as one of the potential solutions to stated problem. One of the main results of the research work is the implementation of prototype of the full-cycle model transformation chain starting from the UML domainmodel and ending with internal Java-based DSL grammar implementation.

In this paper we present DOMMLite - an extensible domain specific language (DSL) for static structure definition of data base oriented applications. The model-driven engineering (MDE) approach, an emerging software development paradigm, has been used. The language structure is defined by the means of a meta model supplemented by validation rules based on Check language and extensions based on Extend language, which are parts of the openArchitectureWare framework [1]. The meta model has been defined along with the textual syntax, which enables creation, update and persistence of DOMMLite models using a common text editor. DSL execution semantics has been defined by the specification and implementation of the source code generator for a target platform with an already defined execution semantics. In order to enable model editing, a textual Eclipse editor has also been developed. DSL, defined in this way, has the capability of generating complete source code for GUI forms with CRUDS (Create-Read-Update-Delete-Search) and navigation operations [2,3,4,5].
