- Support refugees, stateless individuals, and marginalized communities

### 1.2 Scope

This specification covers:
- Digital identity data structures and schemas
- Credential issuance and verification protocols
- Rights management and enforcement mechanisms
- Cross-border recognition and interoperability
- Security and privacy requirements
- API specifications and SDKs

### 1.3 Terminology

- **Digital Citizen**: An individual with a verified digital identity in the WIA system
- **Citizen ID**: Unique identifier assigned to each digital citizen
