titleNotes 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


Terminology Alignment (WIP)

Seatting.pptx

Aligning on information types terminology is critical.

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

...

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