    Scoped OpenAPI 3.0 description of the publicly accessible, read-only Borealis
    (Canadian Dataverse Repository) endpoints used to query the University of
    Alberta research data collection (subtree "ualberta"). Borealis runs the

    by the server at https://borealisdata.ca/openapi (OpenAPI 3.0.3, Dataverse
    API, v6.8.1-SP). This document captures only the public Search and Info
    operations confirmed live against the production host. API tokens
    (X-Dataverse-key header) are required only for account-scoped or write
    operations; public searching is open.
