Which clinical vocabulary standard uses a description logic–based formalism and is considered the most semantically rich for representing clinical concepts?

In the context of HL7 CDA and FHIR, 'value set binding' means:
Answer: Specifying which set of codes from a terminology is valid for a given data element
Value set binding in HL7 standards specifies the allowed coded values (from one or more terminologies) for a particular data element, ensuring semantic interoperability.
The Value Set Authority Center (VSAC) is the authoritative repository for value sets used in which US health IT program?
Answer: ONC Certified EHR Technology (CEHRT) quality measures
VSAC, maintained by NLM, is the authoritative source for value sets referenced in ONC-certified EHR quality measures and clinical quality measures (CQMs).
A 'concept orientation' in a clinical terminology means that:
Answer: Each code maps to exactly one unique clinical meaning with no ambiguity
Concept orientation means each concept in the terminology has a single, unambiguous meaning, distinguishing it from older classification systems that allowed one code to represent multiple meanings.
