datacommons 0.1.1

CRAN release: 2026-09-19

• dc_get_observations(return_type = "data.frame") again populates facet_name. The API no longer returns importName, so the facet name is now derived from provenanceId when needed.

• dc_get_observations(return_type = "data.frame") now returns an empty data frame with a warning when a query matches no observations, instead of failing inside merge().

• dc_post_sparql() is deprecated because the public Data Commons API has retired its SPARQL endpoint (HTTP 410). It still works against custom deployments that support SPARQL, but will be removed in a future release.

• Requests no longer send an empty API key. When no key is set, the key query parameter and the X-API-Key header are left out, so the package works with custom Data Commons deployments that don’t require authentication (@novica, #13).

• New vignette vignette("using-un-data-commons") shows how to use the package with the UN System Data Commons, a custom deployment that doesn’t need an API key (@novica, #13).
