Failure to identify violation of Inheritance Principle #2224
Description
Related to bids-standard/bids-specification#2155.
Aware that this issue, or the others linked below, may not be rectified in the legacy validator due to deprecation; posting here nevertheless for completeness.
Singular failure unique to legacy validator
For a given data file, it is not permissible for there to be multiple applicable JSON metadata files at a single filesystem hierarchy level.
The legacy validator fails to identify this issue in datasets: ip112e1bad, ip170e2, ipmultielfce1v2, as provided in: bids-standard/bids-examples#504.
This applies to BIDS versions 1.1.2 (first online), 1.7.0 (change to Inheritance Principle), 1.10.0 (latest).
The schema-based validator correctly flags these datasets as being in violation.
Failures common to both validators
To avoid replication, and given that there are no issues present in the schema-based validator that are not also present in the legacy validator, I am going to post the list of issues that I have observed that are common to both validators over on the schema validation repository and link here.
