-This bundle provides the Timeline domain object type, as well
-as other associated domain object types and relevant views.
-
-# Implementation notes
-
-## 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)
-    }
-}
