Auto-Classification Workflow
OpenMetadata identifies PII data and auto tags or suggests the tags. It automatically detects sensitive data and assigns relevant tags such as 'PII Sensitive'. The addition of tags about PII data helps consumers and governance teams identify data that needs to be treated carefully.
In the example below, the columns ‘last_name’ and ‘social security number’ are auto-tagged as PII-sensitive. This works using NLP as part of the profiler during ingestion.
{% image src="/images/v1.6/how-to-guides/governance/auto1.png" alt="User_name and Social Security Number are Auto-Classified as PII Sensitive" caption="User_name and Social Security Number are Auto-Classified as PII Sensitive" /%}
In the below example, the column ‘number_of_orders’ is also auto-tagged as Sensitive, even though the column name does not provide much information.
{% image src="/images/v1.6/how-to-guides/governance/auto2.png" alt="Column Name does not provide much information" caption="Column Name does not provide much information" /%}
When we look at the content of the column ‘number_of_orders’ in the Sample Data tab, it becomes clear that the auto-classification is based on the data in the column.

Tag Mapping
Tag mapping is supported in the backend and not in the OpenMetadata UI. When two related tags are associated with each other, applying one tag, automatically applies the other tag. For example, when the tag Personal Data.Personal is applied, it automatically applies another tag Data Classification.Confidential. That way, applying the tag Personal automatically applies the tag Confidential.
