  The aim of this paper is to present the construction of a general family of
C*-algebras which includes, as a special case, the "quantum spacetime algebra"
introduced by Doplicher, Fredenhagen and Roberts. It is based on an extension
of the notion of C*-completion from algebras to bundles of algebras, compatible
with the usual C*-completion of the appropriate algebras of sections, combined
with a novel definition for the algebra of the canonical commutation relations
using Rieffel's theory of strict deformation quantization. Taking the
C*-algebra of continuous sections vanishing at infinity, we arrive at a functor
associating a C*-algebra to any Poisson vector bundle and recover the original
DFR-algebra as a particular example.
