Hi, there is an issue (#010913) about complex datatypes for persistent object. I don't know in deep about the disussion - but I just have an idea:
Wouldn't it be good to have a dedicated Datatype component? This component could cover things like validation, conversion (to an internal representation and between different representations e.g. degree Celsius and Farenheit), and provide datatype specific operators, e.g. calculating a distance between two location-related datatypes. This component could be used in several places: - input validation - business objects - persistent object What do you think about such a component?
