Quality checks

At a glance

Quality checks let you define validation rules on your instances and monitor the overall health of your data. Create automated verifications (non-empty field, email format, numeric range, freshness), view scores per entity type, and manage quarantined instances.

Before you begin

• You must have the governance.admin scope to create checks.
• Entity types and instances must exist in your ontology.

Steps

Create a quality check

1. Open the Governance module from the sidebar.
2. Select the Quality tab.
3. Click New check.
4. Configure the parameters:

Parameter	Description	Example
Entity type	The entity concerned.	Supplier
Property	The field to verify.	email
Check type	The validation rule.	See table below
Severity	Impact on failure.	Warning, Error, Critical
Action on failure	Behavior if the check fails.	Log, Quarantine, Block

Available check types:

Type	Description	Configuration example
Non null	The field must not be empty.	—
Unique	The value must be unique across all instances.	—
Regex	The value must match a pattern.	^[a-z0-9._%+-]+@[a-z0-9.-]+$
Range	The numeric value must be within an interval.	min: 0, max: 100000
Enum	The value must belong to a predefined list.	active, inactive, suspended
Freshness	The data must not be older than a given delay.	24 hours
Reference	The value must reference an existing instance.	type: Supplier

5. Click Save.

Run a check manually

1. In the check list, click the Run button to the right of the desired check.
2. The check runs on all instances of the concerned entity type.
3. Results display the number of compliant and non-compliant instances.

View the quality dashboard

The dashboard displays a quality score per entity type:

• Green (> 80%): satisfactory quality
• Yellow (50-80%): attention required
• Red (< 50%): corrective action needed

Each row shows the entity type, number of instances, overall score, and active checks.

Manage quarantine

When a check is configured with the Quarantine action, non-compliant instances are isolated:

1. Open the Quarantine section in the Quality tab.
2. View the list of quarantined instances.
3. For each instance, you can:
   • Fix: modify the instance, then release it.
   • Release: put the instance back in service without modification.
4. The check that triggered the quarantine is indicated for each instance.

Expected result

Your data is continuously monitored by automated checks. The quality dashboard gives you an overview per entity type, and non-compliant instances are isolated in quarantine for correction.

Limitations and common errors

Situation	Solution
The quality score does not update	Scores are recalculated on each check execution. Rerun the check manually.
Too many instances in quarantine	Adjust the check severity or fix the data in bulk via import.
The regex check does not work	Verify the regular expression syntax. Test it on a sample.
"No entity type available"	First create entity types in the Ontologie.
