A task is a certain [[SYSCLS TASK|classified]] {{UBIK}} object which poses an overall status (Finished / Open).
A task is considered as finished if all the [[SYSCLS_TASK#Validated_MetaProperties|importantdedicated]] properties are validated. Otherwise, it is considered as open.
{{Attention|A property is validated as soon as the user confirms the editing, e.g. through the {{key press|OK}} in a property editor. This has nothing to do with the property value, meaning a property can be validated even if its value is null.}}
