(…) We are following with great interest the development of the TRIMARAN III service, provided by CLS, especially its ability to correlate information of different kinds. We have recently conducted several experiments, which have allowed us to evaluate CLS services.

These experiments have been promising and have allowed us to understand the qualities and areas for improvement. We remain convinced that part of the success lies in the ability to correlate data from various sensors. The last query showed the using the new TRIMARAN III portal was intuitive.
