Third-party material bundled with coreval
=========================================

coreval's own R code is MIT licensed; see the package's LICENSE file.

The files below are NOT coreval's own work. They come from two MIT-licensed
repositories published by CDISC, and the notice that licence requires is
reproduced in full at the end of this file:

  * cdisc-org/cdisc-open-rules      - the rule definitions and their test data
  * cdisc-org/cdisc-rules-engine    - the offline standards-metadata caches
                                      that project commits to its own git

Each entry below names which of the two it came from.


inst/extdata/rules.rds
----------------------
From cdisc-org/cdisc-open-rules. 797 conformance rule definitions - the check
logic, scope, messages, cited guidance and conformance-rule identifiers -
extracted at build time from a pinned commit of that repository. The commit is recorded in
data-raw/UPSTREAM_SHA and available as attr(list_rules(), "rules_version").

inst/extdata/library_variables.rds
inst/extdata/sdtm_model_variables.rds
inst/extdata/sdtm_model_dataset_variables.rds
inst/extdata/ct_packages.rds
inst/extdata/sdtm_domain_classes.rds
----------------------------------
From cdisc-org/cdisc-rules-engine. CDISC standards metadata - variable names,
labels, roles, data types, Core designations, observation classes and
Controlled Terminology package dates. Extracted at build time from the offline
caches (resources/cache/*.pkl) that CDISC's own rules engine commits directly
to its repository, not downloaded: no CDISC API is contacted at build or run
time.

tests/testthat/fixtures/
------------------------
From cdisc-org/cdisc-open-rules. Test data and expected results published
alongside the rules, used to verify coreval's implementation against CDISC's
own reference output.
