The v2 completely restructured this into\n5 representations within the digital health enterprise architecture, each with\nalphanumeric codes (A1–A9, B1–B8, C1–C11, D1–D8, E1–E2).\n\nSeveral new v2 categories have no v1 equivalent:\nA3 (Decision support), A4 (Diagnostics), B1 (Blood bank), B3 (Health program monitoring),\nB7 (Patient administration), C4 (Facility registries), C5 (Health worker registry),\nC7 (Immunisation information), C8 (Master patient index), C9 (Product catalogues),\nC10 (Public Key directories), D1 (Analytics), D3 (Data warehouses).",
