Special provisions for blocking rules and for soft rules
Article 4
1. Input data not complying with a blocking rule shall be rejected from being entered and stored in the VIS Central System. Where the input data does not comply with a blocking rule, the data-quality compliance mechanism shall return an error message and provide guidance to the user on the correct way to make the input data comply with the blocking rule. 2. Input data not complying with a soft rule shall be entered into the VIS Central System with a data quality issue flag, notification or warning message. Where the input data does not comply with a soft rule, the data-quality compliance mechanism shall allow the entry of the data, return a warning message and provide guidance to the user on the correct way to make the input data comply with the soft rule. 3. Data fields which are essential for the functioning of the VIS shall have a blocking rule. The data fields to which a blocking or a soft rule shall apply are defined in the technical specifications. The technical specifications shall be developed by eu-LISA.
