# 5 Cross Functional Requirements

## **5.1 Requirements** <a href="#id-5.1-requirements.2" id="id-5.1-requirements.2"></a>

The Cross Functional Requirements described in this section are an extension of the Cross Functional Requirements defined in the govstack-cfr-architecture-2-1 [Architecture specification](https://govstack.gitbook.io/specification/v/1-0/architecture-and-nonfunctional-requirements) and govstack-cfr-security-2-1 [Security requirements](https://govstack.gitbook.io/specification/v/1-0/security-requirements).&#x20;

This section highlights cross-functional requirements for the Digital Registries Building Block and in addition, describes any supplementary cross cutting to the Architecture Building Block cross-cutting requirements.

## **5.2 Supplementary/Elevated Cross Cutting Requirements** <a href="#id-5.2-supplementary-elevated-cross-cutting-requirements" id="id-5.2-supplementary-elevated-cross-cutting-requirements"></a>

### Comply with high quality data protection principles&#x20;

From **\[RECOMMENDED EXTENSIBLE AUDITABLE]** to **\[REQUIRED EXTENSIBLE AUDITABLE].** This was updated due to the level of data being held in Registries mandating this control.

### Deleting records preserves logical records unless hard deletion is mandated by law&#x20;

From **\[RECOMMENDED REPLACEABLE AUDITABLE]** to **\[REQUIRED REPLACEABLE AUDITABLE].** This was updated due to the level of data being held in Registries mandating this control.

{% hint style="info" %}
There are a number of standards that are especially relevant to Digital Registries that should be considered in an implementation our guidance on these can be found [here](/development/10-other-resources/10.5-cross-functional-security-and-interoperability-standards.md).
