  title: University of Alberta Research Data (Borealis Dataverse) Info Search API
  description: 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 open-source Dataverse software; the full machine-readable spec is published 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.
