## Model Properties
|
|
|
|
The properties below record properties relevant to using and
|
|
understanding timelines based on their JSON representation.
|
|
Additional common properties, such as `modified`
|
|
or `persisted` timestamps, may also be present.
|
|
|
|
### Timeline Model
|
|
|
|
A timeline's model looks like:
|
|
|
|
```
|
|
{
|
|
"type": "timeline",
|
|
"start": {
|
|
"timestamp": <number> (milliseconds since epoch),
|
|
"epoch": <string> (currently, always "SET")
|
|
},
|
|
"capacity": <number> (optional; battery capacity in watt-hours)
|
|
"composition": <string[]> (array of identifiers for contained objects)
|
|
}
|
|
```
|
|
|
|
The identifiers in a timeline's `composition` field should refer to
|
|
other Timeline objects, or to Activity objects.
|
|
|
|
### Activity Model
|
|
|
|
An activity's model looks like:
|
|
|
|
```
|
|
{
|
|
"type": "activity",
|
|
"start": {
|
|
"timestamp": <number> (milliseconds since epoch),
|
|
"epoch": <string> (currently, always "SET")
|
|
},
|
|
"duration": {
|
|
"timestamp": <number> (duration of this activity, in milliseconds)
|
|
"epoch": "SET" (this is ignored)
|
|
},
|
|
"relationships": {
|
|
"modes": <string[]> (array of applicable Activity Mode ids)
|
|
},
|
|
"link": <string> (optional; URL linking to associated external resource)
|
|
"composition": <string[]> (array of identifiers for contained objects)
|
|
}
|
|
```
|
|
|
|
The identifiers in a timeline's `composition` field should only refer to
|
|
other Activity objects.
|
|
|
|
### Activity Mode Model
|
|
|
|
An activity mode's model looks like:
|
|
|
|
```
|
|
{
|
|
"type": "mode",
|
|
"resources": {
|
|
"comms": <number> (communications utilization, in Kbps)
|
|
"power": <number> (power utilization, in watts)
|
|
}
|
|
}
|
|
```
