Data Categories Reference

Data Categories are labels to describe the type of data processed by your software. Data Category objects form a hierarchy: A Data Category can contain any number of children, but a given Category may only have one parent. You assign a child Category to a parent by setting the child's parent_key property. For example, the user.job_title Category is used for personally-identifiable job title information for a user.

These are most heavily used by the System and Dataset resources, where you can assign one or more data categories to each field.

Object Structure

fides_key     constrained string

A string token that uniquely identifies this Data Category. The value is a dot-separated concatenation of the fides_key values of the resource's ancestors plus a final element for this resource:


The final element (this_data_category) may only contain alphanumeric characters and underscores ([A-Za-z0-9_.-]). The dot character is reserved as a separator.


A UI-friendly label for the Data Category.


A human-readable description of the Data Category.


The fides key of the Data Category's parent.

organization_fides_keystringdefault: default_organization

The fides key of the organization to which this Data Category belongs.

Extensibility and interoperability

Data Categories in the taxonomy are designed to support common privacy regulations and standards out of the box, these include GDPR, CCPA, LGPD and ISO 19944.

You can extend the taxonomy to support your system needs. If you do this, we recommend extending from the existing class structures to ensure interoperability inside and outside your organization.

If you have suggestions for core classes that should ship with the taxonomy, please submit your requests here.

Top Level Data Categories

There are two top-level categories:

Label Parent Key Description
system - Data unique to, and under control of the system.
user - Data related to the user of the system.

For each top level category there can be multiple subcategories that provide richer context.

Below is a reference for all subcategories of system and user to assist with describing all data across systems.
