Where are the original DialogColumn Template values stored?

Hello OneIM People,

Using object browser, if you expand the template of a DialogColumn e.g. Person.CentralAcocunt, by clicking the arrow; one can view the ootb template of that column under "Original Value".

To no surprise, there is no column called "Original Value" when one looks at the database. So all that remains is the customizer... does anybody know where the original DialogColumn templates are stored?

Thanks in advance!
