Asserted Value Sets In LexEVS

Asserted Value Sets are not a formal model element in LexEVS.  There is no asserted value set object to instantiate, instead these value set representations are expressed directly in the terminology and represented in ways similar to LexEVS models of Value Set Definitions and Coding Schemes.

 

Value Sets Asserted In The NCI Thesaurus

Value Sets have been asserted directly in the NCI Thesaurus by creating a set of properties and relationships within the original OWL file to describe a "top node," and a set of related values associated with that node.
