ClinCoder Validator v2

Which published CDISC CORE rules apply to your SDTM domains and variables — with official rule ids, the exact CDISC non-conformance message, the standards versions, and CDISC’s own executability rating.

This reports applicability, not results. The rules are not executed against subject data. It answers “which rules govern this dataset”, never “did this dataset pass”.

Try it

curl -s https://validator-v2.clincoder.cloud/api/sdtm/applicable \
  -H 'Content-Type: application/json' \
  -d '{"domains": {"DM": ["USUBJID", "AGE", "SEX"], "AE": []}}'

A domain with an empty variable list still returns that domain’s own rules — DM alone carries 109.

How this differs from v1

	validator (v1)	validator-v2
Input	ARS ReportingEvent JSON	SDTM domains & variables
Rules	21, hand-written in the app	981 published CDISC CORE rules
Source	lambdas in `app.py`	the knowledge graph
Executes rules?	yes, its own 21	no — applicability only

v1 is still running and is unchanged. The two answer different questions; neither replaces the other.
