I just tested that: I exported a Query in Anyblock protobuf format with all switches on.
Then I imported the file into another Space.
The result was partly better then expected: the Objects’ Creation Dates was identical to the source – very good!
Last time when I exported/imported a whole Space, this date became overwritten.
But, unfortunately, the Query itself wasn’t included into the import. As far as I understood the OP, this would have been what he wanted.
