Stream: IG creation
Topic: intensional definition of a SCT ValueSet
François Macary (Mar 10 2020 at 16:08):
I have an example ValueSet in the order-catalog IG, which is intensionally defined with a series of filters is-a. The expansion generated in the output contains only the descendants of each filter "is-a". It misses the concept value of the is-a property.
For instance:
<include>
<system value="http://snomed.info/sct"/>
<filter>
<property value="concept"/>
<op value="is-a"/>
<value value="4598005"/>
</filter>
</include>
generates the 11 descendant of 4598005 |Osteomalacia (disorder)| in the expansion, but misses the Osteomalacia itself.
Since my ValueSet has six include clauses constructed like this, in the end, the expansion misses 6 concepts.
I believe that concept is-a concept id should include all descendants and also the concept id itself, as stated in the standard for using SCT in FHIR
So there may be an issue with the expansion process of the IG builder in this case.
The example value set is here
