Inspect packaged reference-table provenance

Lists packaged lookup objects and identifies whether each is still used internally. The municipal reference has a pinned official source and an explicit snapshot version. The other six legacy objects retain unknown source dates rather than inferred provenance.

Usage

datasus_reference_tables()

Value

A tibble with source, date basis, source version and archive checksum where known, dimensions, role, and a SHA-256 checksum of each serialized table.

Details

For tabMun, source_date is the TXT members' modification date inside the official ZIP, not the validity date of all territorial attributes or the package's original extraction date. Processors apply this fixed snapshot; they do not select territorial boundaries from observation dates. The original TXT members are supplied in system.file("extdata", "territory", "tabmun-source.zip", package = "microdatasus"). See tabMun for the documented compatibility transformations.
