Les premières données et les données suivantes comprennent, de préférence, au moins un des éléments suivants : texte; image; logos; cartes; cartes de texture; symboles; code à barres; caractères et images photographiques. Les règles préétablies peuvent concerner le format et la présentation des instruments commerciaux et des instructions de génération de modèle.
