The Lie n-algebra that generalizes the Poisson bracket from symplectic geometry to n-plectic geometry: the Poisson bracket -algebra of local observables in higher prequantum geometry.
The detailed discussion is currently still here at n-plectic geometry.
slice-automorphism ∞-groups in higher prequantum geometry
higher and integrated Kostant-Souriau extensions
(∞-group extension of ∞-group of bisections of higher Atiyah groupoid for -principal ∞-connection)
