On October, 2nd, 3rd and 4th at the Institute of Catalan Studies (Barcelona) a scientific meeting was held between the Tunisian and Catalan TIR-FOR teams. It was a very fruitful event in which the collaboration of the Tunisian team chaired by Dr. Fathi Bejaoui to the online TIR-FOR project was tightened. One of the most interesting topics was how to optimise the information contained in the Tunisian archaeological chart, that is being successfully carried out in Tunisia, to be included in the TIR-FOR database.
