L’intérêt de la MIT est qu’elle tient en quelques lignes, donc pas besoin d’être juriste pour l’adapter à ses besoins :
Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the “Software”), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
The Software is provided “as is”, without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose and noninfringement. In no event shall the authors or copyright holders be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise, arising from, out of or in connection with the software or the use or other dealings in the Software.
Alors que la GPL et la CC sont plus compliquées et longues…
On voit qu’on peut ajouter des restrictions dans le paragraphe du milieu, par exemple :
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software; if the Software is modified, then the modified version’s title shall be distinguishable from the original’s title, and the modified version shall not pretend to apply to the Ğ1 currency. The derived versions may not be subject to the two latter conditions.
Cette modification oblige à changer le titre si le contenu est modifié, mais n’impose pas cette condition aux licences dérivées. On pourrait aussi remplacer Software par un autre mot.
