Section 70 of 83
69. API Architecture
Stable section ID: S05-CON-005-SECTION-70 · 35 content blocks
The System05 API Architecture enables authorized software and hardware systems to discover, read, configure, monitor, and interact with interfaces and Cartridges.
APIs shall be organized by responsibility rather than exposing unrestricted internal access.
Expected API categories include:
Identity API;
Registry API;
Compatibility API;
Capability API;
Configuration API;
State API;
Event API;
Inspection and Maintenance API;
Digital Passport API;
Building BIOS API;
Digital Twin API;
Robotics API;
Certification and Evidence API;
Emergency Information API.
Every API operation shall define:
requesting identity;
required authorization;
target resource;
input schema;
output schema;
units and coordinate system;
version;
validation rules;
error behavior;
audit requirements;
- rate and timing limits where applicable.
- Read, command, configuration, safety, and administrative operations shall use separate permission levels.
APIs shall support explicit failure responses. A request shall not be treated as successful when it has been accepted for processing but not physically completed.
Idempotency, transaction integrity, state conflicts, retries, communication loss, and partial completion shall be addressed for operations affecting physical systems.
Safety-critical operations may require local authorization, multi-party approval, physical presence, hardware interlock, or confirmation of resulting state.
The API Architecture shall remain vendor-neutral. Proprietary extensions may be provided without preventing access to required standardized functions.
Detailed protocols, transport mechanisms, schemas, and authentication standards remain TBD.
