at least austria recognizes a separate copyright for list compilations that apply to the whole list but not the individual entries. a phonebook for example, or a pricelist. you can use the individual entries (based on their own copyright if one applies) but not duplicate the list as a whole.
but can you recreate your own list which will be definition be very similar to the original? If not it is first past the post rights to public domain data, which has always been my major objection to database/digitization rights.
i suppose it depends on where you get the data from. like implementing your own version of a function, if you can demonstrate that you haven't looked at the other implementation you should be fine.
