Vocabulary Binding Semantics (VBS) Project - INACTIVE

HL7 Project Insight # 1325


This project builds upon the work of the Value Set Definition and deeply integrates with the Value Set Binding Semantics Project. This project seeks to define a standard that specifies what content belongs in a value set expansion, how that can be defined, and will include how an expansion may be constrained for a particular use, such as the FHIR Expansion Profile.
