Reference Implementation

The GA4GH VA-Spec Python Reference Implementation, primarily used for creating Pydantic classes for validation, will support all types covered by the VA-Spec and the more foundational specifications on which it depends, including vrs, cat-var, and the gks-core. It is currently used in MetaKB and GKS ClinVar-This.

The VA-Spec MAY be used without using this Python implementation.
