Elements are defined by JSON-LD. As of 2023-02-12, the most current JSON-LD context for vaccines and for test results is here . Note that the URIs for the DIVOC-specific JSON-LD contexts embedded in the certificates do not resolve.
DIVOC's documentation is here but this does not include element-level descriptions (e.g., terminology bindings at a per-element level).
Terminology bindings at the element level must be inferred from more general documentation. The `v2` JSON-LD context introduces the `evidence.icd11Code` element for vaccines, but there is no documentation on which codes this element is bound to or whether this is used in production. There is no other computable representation of vaccine type/product.
