Indeed.

The DCC / European system (well, eHealth Network to be precise) consists of a technical system (code at https://github.com/eu-digital-green-certificates/dgc-gateway) that collects ‘root certificates’ of each countries within the context of the pandemic. These sign document signer certificates - which in turn sign the Qr codes. This is very similar to the ICAO master lists used for electronic cross board passports.

Joining this network is a technical and legal/governance process:

And this is handled by the technical working groups; with the vocabulary, schema and similar kept at:

	https://github.com/ehn-dcc-development/ehn-dcc-valuesets
	https://github.com/ehn-dcc-development/ehn-dcc-schema
	https://github.com/ehn-dcc-development/dgc-business-rules

And changing/evolving almost as rapidly as the pandemic response.
