title	Notes from Kickoff

Below is the start of translating the uServices definitions of seating capabilities to a technology neutral tabular format as agreed in our kick-off meeting on October 18th. Please take a look, iterate, comment and let me know if you have questions Paul Boyes

Agreed by Group:

Start a position D in architecture - see architecture diagram below
Safety considerations to be noted but not exhaustively

Notes:

- Seating accounts for over 1/5th of VSS.yaml. This is due to the many facets of seating and the number of instances.
- Seat Configuration:
  - Vehicle.Cabin.SeatRowCount - number of rows - defaults to 2
  - Vehicle.Cabin.SeatPosCount - array of number of seats per row - defaults to 2,3 which is 2 in row 1 and 3 in row 2

- - Even though the default says only 2 seats in row 1, generated (yaml) it has Driver, Middle and Passenger
- Related:
  - Vehicle.VehicleIdentification.VehicleSeatingCapacity - provides seating capacity vehicle
  - Vehicle.Cabin.DriverPosition - driver left, middle or right

Seat Identity

Identifying a specific seat within a vehicle. This is based on location within the vehicle.
