Méfiez-vous des imitations [fr] (posted by Fabien Villard)

Le Praxeme Institute respecte quelques principes forts dans ses travaux et Praxeme est l’expression même de ces principes. Au coeur de notre reflexion est la rigueur.

See notes at the end of the post Scoping The scoping aspect (also known as politics aspect) is the pre-modeling concern before real modeling efforts of the upstream aspects (semantic, pragmatic and geographic).
