The OntologyChoice object has the following structure:
| Parameter | Type | Description |
|---|---|---|
| choice * | string | The name of the choice. |
| display | string | The displayed name of the choice. |
| description | string | The description of the choice and any labeling guidance which can be provided. |
| subchoices | Array<OntologyChoice | string> | Sub-choices to be shown under this parent label. Array can be a mix of OntologyChoice objects or strings. |
A simple example is illustrated in the example JSON below, where ontology can simply be a list of strings or OntologyChoice objects.
While there may be a large number of total choices, subchoices allows the tasker to easily navigate the contents and understand the taxonomy better.
ontology = [
"Road",
{
"choice": "Vehicle",
"description": "a means of carrying or transporting material",
"subchoices": ["Car", "Truck", "Train", "Motorcycle"]
},
{
"choice": "Pedestrian",
"subchoices": [
"Animal",
{"choice": "Ped_HeightOverMeter", "display": "Adult" },
{"choice": "Ped_HeightUnderMeter", "display": "Child" },
]
}
