@nzvyagina I really like your approach.
But
brakes the rule that MEASUREMENT.value_as_concept_id belongs to ‘Meas Value’ domain.
Personally, I don’t like this rule. @Christian_Reich, why do we even have this restriction?
You’re talking about FACT_RELATIONSHIP.relationship_concept_id, right?
In this case we can use only Standard concepts with vocabulary_id = ‘Relationship’.
We can’t just pick the standard concept with corresponding meaning (like 4023266 (Has Specimen) which is a SNOMED Observation).
@nzvyagina, please make the list of concept names for new relationships. So, we can discuss and add them to the vocabulary then.
