This discussion shows that SQL queries can be constructed (like Achilles Heel) for OMOP Vocabulary. OPCS4 to SNOMED mapping issues
I have also filed a request for some more conventions for each release here https://github.com/OHDSI/Vocabulary-v5.0/issues/187
Can we please add a folder QualityAssesment
to this repo https://github.com/OHDSI/Vocabulary-v5.0 and collect some notes and code there.
For example we can start with query suggested by in the above thread and a query that counts active and deprecated concepts and compares it to the previous release)
Github issues in https://github.com/OHDSI/Vocabulary-v5.0 can be used to suggest new Vocab DQA ideas and code.
