  Variable and item metadata of the CDISC standards (SDTM model, SDTMIG,
  SDTMIG-AP, SDTMIG-MD, SENDIG, SENDIG-AR, SENDIG-DART, SENDIG-GeneTox,
  ADaMIG, ADaMIG-MD, ADaMIG-NCA, ADaM ADAE, ADaM BDS for TTE, ADaM OCCDS,
  ADaM popPK, CDASH Model, CDASHIG, and QRS supplements).  The standards
  are Copyright (c) Clinical Data Interchange Standards Consortium (CDISC).
  The tables carry only the metadata fields that implementations need:
  variable and dataset names, labels, types, roles, core designations,
  codelist references, order, and (for CDASH) the data-collection question
  text and prompt, and (for QRS) the item order, test names and C-codes.
  The guides' descriptive text, notes, definitions, mapping instructions,
  implementation notes, and the instruments' own item wording are not
  included.  The CDISC Library exports they were built from are used under
  CDISC's download terms and are not redistributed; data-raw/ reads them
  from a folder outside the package (see data-raw/README.md).
