This WHO Digital Documentation of COVID-19 Certificates (DDCC) Implementation Guide details how to use Health Level 7 (HL7) Fast Healthcare Interoperability Resources (FHIR) for consistent digital representation of COVID-19 certificates and interoperability.
This release of the implementation guide is based on the content at https://github.com/WorldHealthOrganization/ddcc/tree/v1.0.0
This implementation guide is undergoing continuous development and implementers should consider the following:
- The package name
who.int
is maintained for compatibility but is expected to change for future releases.- Some artifacts will change their names to follow a consistent naming convention.
- There are known issues in some artifacts.
This implementation guide contains a standards-compliant specifications for the DDCC: Vaccination Status and Test Result technical specifications and guidance documents. It explicitly encodes computer-interoperable logic, including data models, terminologies, and logic expressions, in a computable language to support implementation of vaccination and test result use cases by Member States.
To facilitate implementation of effective and interoperable digital solutions:
The DDCC documents contain overviews of high-level use cases for digital COVID-19 certificates, including:
Supporting guidance, recommendations, resources, and standards are included in the References and Dependencies.
This implementation guide is broken into the following levels of knowledge representation:
