WebVMT: Proposal for data sync design, including sensors & GeoJSON

[rjksmith]

WebVMT includes the concept of synchronising arbitrary data with video and location which is critical for, though not limited to, two important use cases:

1. Sensor data collected by mobile video devices, e.g. drones and dashcams;
2. GeoJSON data synchronised with video.

The following design is proposed.

A WebVMT data sync command which consists of:

• A data sync type. The DataCue type of the associated metadata, proposed in the WICG DataCue Explainer, e.g. org.geojson.
• Data sync values. An array of data values, i.e. the raw data bytes, also proposed in the WICG DataCue Explainer.
• Optionally, a data sync path. The path identifier of the path segments associated with the data, which identifies a WebVMT path, i.e. an object moving through the mapped space.

Comments and questions to help refine this proposal for inclusion in the W3C Editor's Draft are welcomed.

Posted Classifying Video Training Data For Machine Learning Using WebVMT to the W3C Community Group, based on this proposal, to address an issue raised in OGC GeoAI.

I wonder whether you consider W3C Web Annotation Model and Protocol.
