Reused software artefacts guarantee their quality and suitable functionality because they have been tested and used before. As a consequence, commercial off-the-shelf (COTS) importation has acquired relevance in the last few years. This paper presents a proposal for integrating COTS into aspect-oriented architectural models that are developed and maintained following the model-driven development (MDD) approach. The proposal is based on the PRISMA approach, which gives complete support to the development of technology-independent, aspect-oriented software architectures. PRISMA integrates COTS into its MDD process to obtain the complete application code automatically. The proposal is illustrated using a case study: a tele-operated robot that has been developed completely using this proposal.
