Topic: Code system property coding binding

Brian Postlethwaite (Feb 08 2022 at 01:45):

Is there a way to bind a valueset to a codesystem property?
I couldn't see any extension for that.
(creating a simple editor for CS and can't spot that)

bind a valueset to a codesystem property

what does that mean?

Brian Postlethwaite (Feb 08 2022 at 02:55):

When the server is validating a coding based property attached to a concept in the CodeSystem, which Valueset the property code comes from.

Brian Postlethwaite (Feb 08 2022 at 02:56):

(or when I'm using a UI to enter in the concepts in the code system - where to source the possible codes from)

Grahame Grieve (Feb 08 2022 at 03:00):

I don't understand. Properties don't come from value sets

Grahame Grieve (Feb 08 2022 at 03:00):

value sets aren't 'bound' to code system properties

Brian Postlethwaite (Feb 08 2022 at 03:01):

Code System Properties can have a coded value in them - what does that bind to?

Grahame Grieve (Feb 08 2022 at 03:01):

why would you be validating a coding based property?

Grahame Grieve (Feb 08 2022 at 03:01):

I don't know what you mean by 'bind'?

Brian Postlethwaite (Feb 08 2022 at 03:01):

Don't we normally have a way of binding any Coding type property?

Grahame Grieve (Feb 08 2022 at 03:02):

you bind an element to a value set. is that what you're asking about?

Brian Postlethwaite (Feb 08 2022 at 03:02):

Yes, the element is a property on a codesystem concept.

Brian Postlethwaite (Feb 08 2022 at 03:03):

e.g. with this example CodeSystem, how do I define the ValueSet to bind for what the Advertising Category property should be bound to?

Grahame Grieve (Feb 08 2022 at 04:00):

well, are you asking about slicing the properties so you can bind, or about what the value set would look like?

Brian Postlethwaite (Feb 08 2022 at 04:24):

I'm asking how I can update this CodeSystem to indicate what valueset to bind to the AdvertisingCategory property definition
i.e. something like this:

<property >
    <extension value="???">
        <valueCanonical value="http://example.org/fhir/ValueSet/advertisingCategories"/>
    </extension>
    <code value="adv"/>
    <description value="Advertising Category"/>
    <type value="Coding"/>
</property>

so that then in the concepts that are listed in that code system lower down...

  <concept>
    <code value="Excel" />
    <display value="Excellent" />
    <property>
      <code value="adv" />
      <valueCoding>
        <system value="http://example.org/fhir/CodeSystem/advertisingCategories" />
        <code value="general" />
      </valueCoding>
    </property>
  </concept>

Grahame Grieve (Feb 08 2022 at 06:02):

we haven't defined any extension like that

Brian Postlethwaite (Feb 08 2022 at 06:35):

I'll log it...
