We construct a moduli space Yμ,τ of Kisin modules with tame descent datum r and with p-adic Hodge type ≤ μ, for some finite extension K/ℚp. We show that this space is smoothly equivalent to the local model for ResK/ℚ GLn, cocharacter {μ}, and parahoric level structure. We use this to construct the analog of Kottwit'z-Rapoport strata on the special fiber Yμ,τ indexed by the μ-admissible set. We also relate Yμ,τ to potentially crystalline Galois deformation rings.
