Will the following syntax:

     a rdfs:Class ;
     rdfs:subClassOf schema:Thing ;
     :property [
         :predicate schema:code ;
         :valueType schema:MedicalCode ;
         rdfs:label "code" ;
         rdfs:comment "A medical code for the entity, taken from a 
controlled vocabulary or ontology such as ICD-9, DiseasesDB, MeSH, 
SNOMED-CT, RxNorm, etc." ;
     ] ; ...

Equate to the following, semantically (represented using "is  of" syntax 

a rdfs:Class ;
rdfs:subClassOf schema:Thing ;
is schema:domainincludes of
                                             rdfs:label "code",
                                             rdfs:comment .

I am hoping the shapes related syntax sugar is distinct from actual 
underlying semantics.
