There have indeed been some changes there somewhere around SMW 1.3/1.4. I assumed that this is a very rarely used feature, hence did not send any warnings. Effectively, there is currently no more datatype enforcement for imported properties and you always need to specify the property datatype explicitly. This is the result of some internal clean up. We currently do not have an architecture that allows one datavalue to set further annotations (this is what needs to happen if imported-from statements shall lead to implicit has- type statements). I am unsure how to best achieve this in a clean way. The historic implementation was not clean, introducing various special cases during parsing. As I said, I did not consider this as a used feature so far (simply because there are only few uses of the RDF export, which is the only thing that importing influences).
