Detailed Description

Holds event message meta data.

You can attach various types of objects (vehicle, person, face, etc.) to an event by setting a pointer to the object in extMsg.

Similarly, you can attach a custom object to an event by setting a pointer to the object in extMsg. A custom object must be handled by the metadata parsing module accordingly.
