# Former API Specs

Reference specifications for the **predecessor / legacy APIs** that ScadaBridge replaces or
interoperates with. These are *not* ScadaBridge's own contracts — they are kept here as
historical reference when porting integrations onto ScadaBridge's Inbound API (#14) and
External System Gateway (#7), and for parity-checking behavior during cutover.

ScadaBridge's own component design docs live under [`docs/requirements/`](../requirements);
this folder holds only the **outgoing/legacy** systems' specs.

## Subfolders

- [`mes/`](mes) — the legacy MES API (ServiceStack "WWSupport / APIServer", a.k.a. `mesapi`)
  that bridges MES ↔ AVEVA Wonderware via MXAccess. Source repo: `~/Desktop/mesapi`.
- [`dnc/`](dnc) — the legacy DNC integration: DELMIA Apriso document/recipe download +
  Wonderware recipe-download notification (`~/Desktop/delmiaintegration`).
