Objective

Good Health Pass compliant implementations must collect, process, and transmit a standard set of data elements.

Terms of Reference

As with passports and payment cards, fully interoperable digital health pass systems need a common data model, specifying standard data elements and supported by specific data schemas in specific implementations. Work in this area is currently ongoing across several cross-industry efforts.

One such effort is the Linux Foundation Public Health (LFPH) COVID-19 Credentials Initiative (CCI), which has established a task force to develop schema specifications, Codes of Practice, technical guidelines, JavaScript Object Notation (JSON) code, and related components. This includes the eHealth Network's Vaccination Proof Interoperability Guidelines.

The CCI task force is also seeking to collaborate with others in this space, including the CDC, the W3C Credentials Community Group, the EU vaccination group, C4 Credentials, IATA, ICAO, public health authorities, private health vendors and consortiums, electronic health record (EHR) providers, the UK National Health Service, pharma companies, major pharmacy chains (US), the FHIR Focus Group at the ToIP Foundation, and the Vaccination Credentials Initiative (VCI).

One example of a data model that enables efficient information exchange across diverse public and private organizations is the U.S. National Information Exchange Model (NIEM). NIEM provides rules and methodologies around the use of the model as well as a standardized Information Exchange Development Lifecycle that can be reused by everyone. NIEM also offers governance, training, tools, technical assistance, and an engaged community to support users and organizations in adopting NIEM.

To emphasize, this is just one example of the kind of approach that the Good Health Pass Collaborative could take to accommodate data requirements of different countries and jurisdictions around the world.

Responsibilities and Deliverables

Key Interoperability Questions (from GHPC Blueprint Outline v2)

What are the minimal required elements for Good Health Pass schemas?
What are the optional, country-specific elements for Good Health Pass schemas?
Is there a data model that will enable both interoperability and adaptability of data elements to different implementations, jurisdictions, and governance authorities?
How does the data model support identity binding (e.g., describing levels of assurance)? (See Challenge #8)
