artoo: Lossless CDISC-Native Input and Output for Clinical Datasets
Reads and writes clinical-trial datasets losslessly across
'SAS' XPORT (XPT), Clinical Data Interchange Standards Consortium
(CDISC) Dataset-JSON, and 'Apache Parquet', applying a specification
to produce submission-ready Study Data Tabulation Model (SDTM) and
Analysis Data Model (ADaM) datasets. A single canonical metadata model
carries labels, CDISC data types, lengths, 'SAS' display formats,
controlled-terminology references, and sort keys identically across
every format, so conversion between any two formats is lossless by
construction. Pure 'R' and lightweight, with no external 'SAS' or
'Java' runtime. Reads and writes CDISC Define-XML, the specification
document that accompanies a submission, and renders it as HTML through
the bundled Define-XML stylesheet. Implements the published format
specifications for CDISC Dataset-JSON
(<https://cdisc-org.github.io/DataExchange-DatasetJson/doc/dataset-json1-1.html>),
CDISC Define-XML
(<https://www.cdisc.org/standards/data-exchange/define-xml>), and
'SAS' XPORT
(<https://www.loc.gov/preservation/digital/formats/fdd/fdd000466.shtml>).
