Reject a Role the SDTM Model Does Not Publish

Review ask

As a clinical trial statistician or programmer, answer two short questions in Your review: the task and the inputs. Agreeing with both approves this benchmark; disagreeing with either needs a comment. Propose a fix with the Edit button on any source file, or add it to your comments.

We suggest spending no more than 5 minutes on a review. The other tabs beside Your review are background for assessment, not under review.

Summary

EditUnder reviewWhat this benchmark means

README.md

Public entries: Python and R. Passing coverage requires an installed inventory.

Goal: carry each subject's age (AGE) with its unit (AGEU), and describe the role the unit plays in the demographics domain.

Input: collected demographics with the study and subject identifiers and each subject's age in years.

Variables:

AGE would be the subject's age in years, as collected.
AGEU would be the unit of that age, YEARS on every record.

Note: the SDTM model publishes nine variable roles: Identifier, Topic, Timing and Rule, and the Grouping, Result, Synonym, Record and Variable Qualifiers. The role written for the age unit, Qualifier, names the group the five qualifier roles belong to rather than one role, so the request is rejected before any data is read, and no artifact is accepted.

How to fix

Name the one role the variable plays. The age unit qualifies the age itself, which the SDTM model calls a Variable Qualifier:

submission:
  core: Exp
  role: Variable Qualifier
  length: 5
  origins:
    - type: Assigned
      source: Sponsor

A role is written exactly as the SDTM model spells it: Variable qualifier is rejected the same way.

Version	Date	Author	Description
1.7	2026-10-20	yamaa docs build	Read a specification in the 1.0 surface as its 0.5 counterpart; state that missing values stay missing where a mapping declares no missing handler, and leave out a declared missing answer that restates a handler's default
1.6	2026-10-17	yamaa docs build	Describe collected date parts written as ISO 8601 date text and times of day counted in seconds since midnight
1.5	2026-10-17	yamaa docs build	Name collected precision in words instead of letter codes; state imputation fallbacks, minimum source precision, bounds ignored outside the collected period, and invalid text with no handler as an error; describe date and datetime shifts, imputation flag codes, and partial text giving no date part
1.4	2026-10-15	yamaa docs build	State datetime precision codes through the hour and minute, and complete only the time parts a collected datetime lacks
1.3	2026-09-29	yamaa docs build	Show study codelist names, external dictionaries, and ISO 8601 formats in variable rows; list the document's codelist values and metadata
1.2	2026-09-29	yamaa docs build	Classify ADaM copies from a declared input as Predecessor and recodes as Derived, and SDTM recodes of locally derived columns as Derived
1.1	2026-09-29	yamaa docs build	Resolve lookups into the donor record they select, and give every derivation shape a plain-language rule instead of its raw YAML
1.0		yamaa docs build	Initial generation from spec.yaml
