  skos:definition """In geometry, a Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of real numbers called coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, called coordinate lines, coordinate axes or just axes (plural of axis) of the system. The point where they meet is called the origin and has (0, 0) as coordinates.
<br/>Similarly, the position of any point in three-dimensional space can be specified by three Cartesian coordinates, which are the signed distances from the point to three mutually perpendicular planes. More generally, n Cartesian coordinates specify the point in an n-dimensional Euclidean space for any dimension n. These coordinates are the signed distances from the point to n mutually perpendicular fixed hyperplanes. 
<br/>(Wikipedia, The Free Encyclopedia, <a href="https://en.wikipedia.org/wiki/Cartesian_coordinate_system">https://en.wikipedia.org/wiki/Cartesian_coordinate_system</a>)"""@en, """Un système de coordonnées cartésiennes permet de déterminer la position d'un point dans un espace affine (droite, plan, espace de dimension 3, etc.) muni d'un repère cartésien. Le mot cartésien vient du mathématicien et philosophe français René Descartes.
<br/>Il existe d'autres systèmes de coordonnées permettant de repérer un point dans le plan ou dans l'espace.
