Parse all metadata from a PUMF version directory

Detects every parseable command-file format in version_dir, runs all applicable parsers, merges the results into the canonical schema, and writes metadata/variables.csv, metadata/codes.csv (and optionally metadata/layout.csv) under version_dir.

Usage

pumf_parse_metadata(
  version_dir,
  layout_mask = NULL,
  metadata_encoding = NULL,
  refresh = FALSE,
  meta_subdir = NULL
)

Arguments

version_dir

Path to the extracted version directory.

layout_mask

Optional string to disambiguate when multiple command-file sets coexist in one directory (e.g. "CDN" for Census); passed through to parse_spss_split and parse_sas_cards.

refresh

If TRUE, re-parse even if cached metadata exists.

Value

metadata_dir path invisibly.

Details

Idempotent: skips parsing if metadata/variables.csv already exists and refresh = FALSE.
