The Model Driven Development (MDD) paradigm uses conceptual models to automatically generate software products by means of model transformations. This paradigm is strongly positioned in industry due to the quickly time to market of software products. Nevertheless, quality evaluation of software products is needed in order to obtain suitable products. Currently, there are several quality models to be applied in software products but they are not specific for conceptual models used in MDD projects. For this reason, it is important to propose a set of metrics to ensure the quality of models used in MDD approaches in order to avoid error propagation and the high cost of correction of final software applications. This paper analyzes the characteristics and sub-characteristics defined in the ISO/IEC 9126 quality model in order to reveal their applicability to MDD conceptual models.
