## Deliverable Snapshot
|
|
|
|
| Section | Highlights | Next Action |
|
|
|---------|------------|-------------|
|
|
| Mermaid ERD | Normalised entity diagram ready for mermaid.live | Share with architects for validation |
|
|
| Entity catalogue | Attributes, data types, keys, derived fields | Flag unknown data types for modelling session |
|
|
| GDPR pack | PII inventory, legal basis, retention, data subject rights | Review with DPO; schedule DPIA if high risk |
|
|
| Governance matrix | Owner, steward, custodian, classification | Update RACI and onboarding materials |
|
|
| CRUD & integrations | Component ↔ entity access + upstream/downstream feeds | Align with API contracts and ETL plans |
|
|
| Data quality | KPIs, controls, monitoring cadence | Feed into ServiceNow service design |
|
|

|
## Compliance Focus
|
|
|
|
- **Identify PII** – mark direct/indirect PII in the catalogue.
|
|
- **Retention** – confirm duration against organisation policy.
|
|
- **Security** – ensure encryption/segmentation controls align with risk appetite.
|
|
- **Subject rights** – validate mechanism for access/erasure/export.
|
|
|
|
Use the output to enrich `/arckit:dpia` (automatic when run afterwards).
|

|
## Review Tips
|
|
|
|
- Run the command whenever requirements change materially.
|
|
- Ask data stewards to sign off catalogue rows before build.
|
|
- Store diagrams alongside other architecture artefacts for audit trails.

## UK Government Data Policy
|
|
|
|
For UK Government data projects, the data model provides evidence for the [National Data Strategy](https://www.gov.uk/government/publications/uk-national-data-strategy/national-data-strategy) — particularly the **Data Foundations** pillar (metadata standards, data quality) and **Availability** pillar (data access controls, sharing agreements). The Data Quality Framework section aligns with the [Government Data Quality Framework](https://www.gov.uk/government/publications/the-government-data-quality-framework/the-government-data-quality-framework) (6 dimensions, 5 principles). See `docs/guides/national-data-strategy.md` and `docs/guides/data-quality-framework.md` for full mappings.
