Building BIOS Architecture

The Interface Registry records every defined Interface Type and every Interface Instance represented within the building.

Each Interface Type record shall include:

Interface Type ID;

domain or multi-domain classification;

version;

Compatibility Class;

Interface Profile;

controlled geometry reference;

Capability Declaration schema;

connection protocol;

state model;

inspection requirements;

safety classification;

evidence and certification requirements.

Each Interface Instance record shall include:

Interface Instance ID;

Type ID;

host component or Cartridge;

physical or logical location;

local coordinate system;

orientation;

current connection counterpart;

current connection state;

negotiated capability;

applicable environmental condition;

lock and verification status;

inspection status;

fault status;

lifecycle history.

The Interface Registry shall represent unoccupied Interfaces as well as occupied Interfaces. Unused Interfaces may require protective covers, isolation, environmental sealing, or reserved-capacity records.

Connection shall be represented as a relationship between two or more Interface Instance IDs. The BIOS shall not store connection merely as text within a component record.

The Registry shall distinguish:

available;

reserved;

partially engaged;

connected but not commissioned;

commissioned;

operational;

degraded;

isolated;

faulted;

disconnected;

permanently closed;

decommissioned.

If both sides of a connection report inconsistent states, the Interface Registry shall preserve both observations and record a State Conflict rather than silently selecting one.
