A Component-Based Approach for Specifying DSML's Concrete Syntax

International audienceModel-Driven Engineering (MDE) encourages the use of graphical modeling tools, which facilitate the development process from modeling to coding. Such tools can be designed using the MDE approach into meta-modeling environments called metaCASE tools. It turned out that current metaCASE tools still require, in most cases, manual programming to build full tool support for the modeling language, especially for users' native methodologies and representational elements and propose limited possibilities in terms of reusability. In this context, we propose MID, a set of meta-models supporting the easy speci cation of modeling editors by means of reusable components and explain how representational meta-modeling is carried out with it

Applying MDA and OMG Robotic Specification for Developing Robotic Systems

Robotics systems have special needs often related with their realtime nature and environmental properties. Often, control and communication paths within the system are tightly coupled to the actual physical configuration of the robot. As a consequence, these robots can only be assembled, configured, and programmed by robot experts. Traditional approaches, based on mainly writing the code without using software engineering techniques, are still used in the development process of these systems. Even when these robotic systems are successfully used, several problems can be identified and it is widely accepted that new approaches should be explored. The contribution of this research consists in delineating guidelines for the construction of robotic software systems, taking advantage of the application of the OMG standard robotic specifications which adhere to the model-driven approach MDA. Thereby the expert knowledge is captured in standard abstract models that can then be reused by other less experienced developers. In addition part of the code is automatically generated, reducing costs and improving quality.Laboratorio de Investigación y Formación en Informática Avanzad

Modeling of Configurations for Embedded System Implementations in MARTE

International audienceThis paper deals with aspects related to modeling of system configurations, which are very useful for describing various states of an embedded system, from both structural and operational viewpoints. We discuss in detail the current proposition of the UML MARTE profile via some examples, and point out some limitations of the current proposition, mainly concerning the semantic aspects of the defined concepts. In order to draw answering elements, we report our experiences about the modeling of implementations and execution modes in Systemson- Chip, within the Gaspard2 SoC co-design framework

Traceability in Model Driven Engineering

Model Driven Engineering (MDE) is an initiative to rais the level of abstraction and ease the complexity in the system development process, trough the use of domain specific languages and transformations. Extensive use of transformations do howerver make it more difficult to see how different artefacts involved in the system development process are related, as the logic of a transformation may not be straight forward. By maintaining traceability links between the various artefacts involved in a development process, it may become easier to analyse the process that have led to certain point in the evolution of a system. The goals of this thesis is to provide a generic tool that makes it posible to define traceability types and to capture traceability information of these types, and to define a simple classification scheme for traceability in MDE

Towards the Performance Analysis of Apache Tez Applications

Apache Tez is an application framework for large data processing using interactive queries. When a Tez developer faces the ful llment of performance requirements s/he needs to con gure and optimize the Tez application to speci c execution contexts. However, these are not easy tasks, though the Apache Tez con guration will im- pact in the performance of the application signi cantly. Therefore, we propose some steps, towards the modeling and simulation of Apache Tez applications, that can help in the performance assessment of Tez designs. For the modeling, we propose a UML pro le for Apache Tez. For the simulation, we propose to transform the stereotypes of the pro le into stochastic Petri nets, which can be eventually used for computing performance metrics
