Ich did a redraw of previous image.
Answers to some points:
@quantumstate: moving license change upwards will not help. If some one wants to import Google Maps data, it is fine to make converter. And make sure all tags are wikidescribed. But not fine to upload, which ist marked. If person can not look ahead on the list she deserves that.
@Gnonthgol: linear path ist for easy understaning. To make sure nothing falls off out mind. Before upload, you look at this again and check whole process following the arrows.
@LivingWithDragons note about revert ist from original import guide lines.
Ich think about giving numbers to blocks for easy reference. Need make sure community do not want add more blocks so numbers do not change.
Ich post link to this to talk@ and imports@ to discuss better.
