We construct via Fraïssé amalgamation an ω-categorical structure whose automorphism group is an infinite oligomorphic Jordan primitive permutation group preserving a `limit of D-relations'. The construction is based on a semilinear order whose elements are labelled by sets carrying a D-relation, with strong coherence conditions governing how these D-sets are inter-related.
