Returns metadata for ADaM datasets following CDISC standards. Provides information about required, conditional, and other variables for each ADaM analysis dataset.
get_adam_metadata(version = "1.3")A named list where keys are ADaM dataset names and values are data.frames with columns:
Variable name (character)
Variable label/description (character)
Data type: "Char" for character or "Num" for numeric
Importance level: "Req" (Required), "Cond" (Conditional)
Character string specifying the ADaM IG version. Supported values: "1.3" (default), "1.2", "1.1".
Note: All versions currently return identical variable definitions. The ADaM IG revisions (1.1 -> 1.3) changed guidance and rules but not the core variable inventory. The parameter exists for provenance tracking only -- it does not enable version-specific validation.
Variable definitions are based on the published CDISC ADaM Implementation Guide. The canonical machine-readable source is the CDISC Library API (https://www.cdisc.org/cdisc-library), which requires CDISC membership. The metadata shipped with clinCompare is hand-curated from the published IG specifications.
