How can we use ValueSet and code systems?

Hello Everyone,

I am a little confused about how can we use code system and valueSet in fhir?

let’s say that I need to use values sets,

so i already added it to answerValueSet property.

but the question is, how can other systems consume it?

When a system sees a canonical reference, they resolve it by looking for a resource with that URL in their registry(ies) of choice. If they can’t find the resource locally or in any of the registries they trust, as a last resort they can try resolving the URL directly.
