A Model Repository Description Language - MRDL

Abstract

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract. Repository-based development of software systems has gained more attention recently by addressing new challenges such as security and dependability. However, there are still gaps in existing modeling languages and/or formalisms dedicated to define model repositories and the way how to reuse them in the automation of software development. Thus, there is a strong requirement for defining a model repository description language not only as a modeling approach, but also as a suitable instrument to support system and software engineers in the activity of search and retrieval of appropriate models beyond keywordbased search. Moreover, modeling approaches allow using tools for the specification and the exploitation of the designed artifacts (e.g. analysis and evaluation). The goal of this paper is to advance the state of the art in model repository description for software and systems engineering. In particular, we have designed a flexible and extensible modeling language, by means of an OMG style metamodel, to specify model repositories for modeling artifacts, and we have defined an operational architecture for development tools. In particular, we show the feasibility of our own approach by reporting some preliminary prototype providing a model-based repository of security and dependability (S&D) pattern models.

A Design-Task-Oriented Model Assignment Method in Model-Based System Engineering

“…is captures the suitability of the model for the task. e literature regarding model management in MBSE and software engineering has focused on model management platform [26], model repository building methods [27], and so on, but has not provided a method for the evaluation of model value for the task. is study applies an advantage-number-based analytical technique to evaluate the models to be assigned from the perspective of value and, accordingly, preferentially filters the models to establish a design-task-oriented preferred model set.…”
