# Capability Model
|
|
|
|
Box hardware is described with resources and capabilities.
|
|
|
|
## Resource
|
|
|
|
A box resource is a physical or simulated component that can be addressed by
|
|
the gateway:
|
|
|
|
- board
|
|
- power supply
|
|
- serial port
|
|
- network port
|
|
- relay
|
|
- sensor
|
|
- simulator endpoint
|
|
|
|
Resources carry lifecycle state such as `available`, `reserved`, `running`,
|
|
`maintenance`, or `offline`.
|
|
|
|
## Capability
|
|
|
|
A capability describes an action or measurement exposed by a resource. Examples:
|
|
|
|
- `power.cycle`
|
|
- `power.set_voltage`
|
|
- `serial.console`
|
|
- `network.link`
|
|
- `firmware.flash`
|
|
- `sensor.read`
|
|
|
|
Capabilities declare:
|
|
|
|
- direction: `input`, `output`, or `bidirectional`
|
|
- value type: `boolean`, `integer`, `number`, `string`, `object`, or `binary`
|
|
- optional unit
|
|
- constraints for allowed values or ranges
|
|
- whether the operation mutates hardware state
|
|
|
|
## Operation Binding
|
|
|
|
Hardware operations reference capabilities by `capabilityId` and resources by
|
|
`resourceId`. Implementations must not infer a capability from a free-form
|
|
operation name when a capability record exists.
