  skos:definition """En mathématiques, la notion de demi-espace peut se définir de façon intuitive comme étant l'une des deux parties de l'espace que l'on aurait partagé avec un plan. En physique, on parle de milieu semi-infini. 
<br/>(Wikipedia, L'Encylopédie Libre, <a href="https://fr.wikipedia.org/wiki/Demi-espace">https://fr.wikipedia.org/wiki/Demi-espace</a>)"""@fr, """In geometry, a half-space is either of the two parts into which a plane divides the three-dimensional Euclidean space. If the space is two-dimensional, then a half-space is called a half-plane (open or closed). A half-space in a one-dimensional space is called a half-line or ray.
