Thanks for the fast reply. What should inherit from what? Class A (e.g. 'todo item') is certainly not derived from property X (e.g. 'startdate'). Class A version 2 has different properties (some are removed, others are added). Can you elaborate / say I'm wrong / give an example ? Thanks,
Mark

Use table inheritance.
