Hello !

I wonder if it is possible to obtain the data history of an instance. For example , what are the annual costs of an application ? Do Protégé retains the data when we change those numbers ? Thank you !

Hi Vincent,

Protege doesn't retain a history of the previous values but we have a feature called "superseded version" which allows you to relate multiple instances which have differing values. This is typically applied to product versions and the like but could in theory be used for what you describe.

However, it's worth pointing out that superseded version isn't supported in any of the out of the box views within the Viewer though you could of course look to implement this yourself.

Cheers

Neil
