Sorry to jump so late into this discussion.
Actually I am waiting for an answer from the imports list since Mid May. I
put it below.
So we would like to know if in the case of using a ODbL compatible dataset
as a guide for tracing over Bing Imagery (because of the lack of
geometrical accuracy) + get some attributes (road names or ID, etc.) is
considered as coming under the usual import pattern (including a specific
import user account) or not.

Actually we would like to be sure if only used as a guide with sometimes
some attributes (eg name) copy and paste on the freshly-new-traced vector
data from Bing imager, it is not considered as an import.
