"/world" frame is typically used to represent absolute positions in the world. It has no parent, so its value is always (0, 0, 0).
(0, 0, 0) in the world frame represents the intersection of the Prime Meridian and the Equator at sea level in outdoor applications, but could represent the southwest corner of a building on the 1st floor, or any other fixed point.
The world frame is your permanent frame. It is the frame against which all other frames are measured. If you're only working inside of a building, your world frame should be a fixed point in that building. If your robot can go anywhere in the world, maybe your world frame should be the world frame I mentioned above.
