Property-Value Journal

A journal feature for a single property is available since version 2.2.1. UBIK® logs changes of property values in the system and provides a mechanism to evaluate information about

  • the user changing a property value
  • the timestamp the property value has changed

The journal feature can be activated for each single MetaProperty, see (Activate Logging of PropertyValues).

IC Hint square.pngOnce the logging is activated, every change on the property will be logged in the database


It is possible to see a list of all changes (per property) by using the Object Explorer. By exploring an instance it is possible to browse through all its properties. If the journal feature is activated, a list of all changes made to a property value can be shown:
