Rating Assurance & Certification

Applications are rated and reviewed before they go live


The HAT Community Foundation Network-Enabled Application (NEA) Data Conduct and Rating Assurance and Certification (DaCRAC) is the review of a set of practices by an NEA that is transparently declared to enable a standardised risk assessment and rating of the app to be conducted.


The DaCRAC standard gives recommendations for developers of NEAs using the Dataswyft platform. It includes a set of quality criteria and covers the application's data conduct and the way data flows are orchestrated on the platform.

The DaCRAC standard only covers the treatment of self-dovereign data.

The Rating Assurance and Certification

Every NEA generates data when a user interacts with it, resulting in the data being stored somewhere. For applications on the Dataswyft platform, the application owner chooses where to store the data; whether it is on a device, in the application’s server, or within a Data Account. The decision of what data, where, and how personal data is stored will be rated by the Dataswyft Rating system using three characters:

First character: Access

The first character specifies where the data is stored: either, on the Data Account, both on the Data Account and the app server, or only on the app server. This character also declares if any Personally Identifiable Information (PII), such as email address, is collected or stored on the app server. If the organisation has rights to retrieve the information e.g. through a contracted Data Account, it is still only for the designated namespaçe. All other namespaces of the database are still private to the Data Account holder. For example, an organisation – let’s call it “Wood Factory” – using Data Accounts for their HR records has C as its first character. This indicates that the organisation does have access to the PII inside their employees' Data Accounts as they have credentials for access into the Wood Factory namespace. Should any individual leave Wood Factory, the organisation credentials would be terminated but the individual as the Data Account holder may be allowed to keep the data within the namespace.

The second character: Conditions

The second character specifies if the application imposes a condition on the user for the data's reuse and re-sharing. Some applications may choose to impose legal restrictions on re-sharing or technical restrictions for re-sharing (such as encryption).

The third character: Completeness

The third character specifies how complete the data is within the Data Account. This includes what may not normally be personal data e.g. the app's metadata, but would still be user-generated.

Merchants declare their rating according to the rating system specified by the HAT Community Foundation when they submit their application for review. The ratings are shown to all Data Account holders on the screen where they agree to the data contract. The Rating Assurance provides individuals with confidence that the website/application displaying the assurance has declared their treatment of personal data on the basis of the standards set out below. This rating assurance is not verified by Dataswyft. Merchants may choose to go beyond the assurance and be certified by the HAT Community Foundation. To achieve the Dataswyft Rating Certification, websites/applications must subject their code to periodic audit to verify that it consistently adheres to the rating declared.
