Retrieves the WQP 3.0 column-name schema mapping WQP Quick Reference Guide.
Arguments
- download_only
Logical. If TRUE, bypasses the cache and package fallback and attempts to download the latest schema reference table directly, returning it without updating the cache. Errors if the download fails. If FALSE (default), uses a cached copy when available and updates the cache; on download failure, falls back to the package’s internal file.
- refresh
Logical. Only used when download_only = FALSE. If TRUE, ignore any cached copy and attempt to retrieve a fresh table (download, falling back to the package’s internal file on failure), then update the cache. If FALSE (default), return the cached table when available. Ignored when download_only = TRUE.
