Logic
If only the ingredient(s) present, construct a Medicinal Product, OR
If form is also present, construct a Medicinal Product Form, OR
If amount is also present construct a Clinical Drug
Construct one role group in the template per ingredient object.
Assertion: Cannot have an amount without form.
Assertion: Cannot have numerator value without denominator value, although this may be "per 1 tablet"
Issues
- Does not allow for amounts being based on the Basis of Substance Strength (BoSS)
- Will we have to create a map for the unit of presentation from the dose form?
- SNOMED CT is still using "concepts as numbers" which we'd have to map to
ingredient.amount.numerator.unit is a string. We'll have to map to the SNOMED CT code from there, if "code" is not supplied. Check system = snomed if code is supplied.
Still waiting for finalization of "Ingredient Count" attribute.
