Topic: error - has children and multiple types

Sean McIlvenna (Aug 13 2018 at 22:33):

I'm getting an error from the IG Publisher:
Observation.valueQuantity has children (Observation.valueQuantity.value) and multiple types (Quantity, CodeableConcept, string, boolean, Range, Ratio, SampledData, Attachment, time, dateTime, Period) in profile BloodPressureObservation.valueQuantity

Sean McIlvenna (Aug 13 2018 at 22:33):

Any idea how to fix this?

Sean McIlvenna (Aug 13 2018 at 22:34):

I've tried restricting the <type> on valueQuantity to just "Quantity"

Sean McIlvenna (Aug 13 2018 at 22:34):

but that didn't help

Lloyd McKenzie (Aug 13 2018 at 22:50):

I think you need to first slice on type, then constrain your slice.

Sean McIlvenna (Aug 13 2018 at 22:51):

this is what I have

Sean McIlvenna (Aug 13 2018 at 22:51):

<element id="value[x]">
  <path value="Observation.value[x]"/>
  <slicing>
    <discriminator>
      <type value="value"/>
      <path value="@type"/>
    </discriminator>
    <rules value="open"/>
  </slicing>
  <short value="value[x]"/>
  <definition
    value="SHALL contain exactly one [1..1] value[x], where value[x] is (CONF:4383-273)"/>
  <min value="1"/>
  <max value="1"/>
</element>
<element id="value[x].valueQuantity:quantity">
  <path value="Observation.valueQuantity"/>
  <sliceName value="quantity" />
  <short value="valueQuantity"/>
  <definition value="valueQuantity (CONF:4383-274)"/>
  <type>
    <code value="Quantity" />
  </type>
</element>
<element id="value[x].valueQuantity:quantity.value">
  <path value="Observation.valueQuantity.value"/>
  <sliceName value="quantity" />
  <short value="value"/>
  <definition value="SHALL contain exactly one [1..1] value (CONF:4383-281)."/>
  <min value="1"/>
  <max value="1"/>
</element>
<element id="value[x].valueQuantity:quantity.unit">
  <sliceName value="quantity" />
  <path value="Observation.valueQuantity.unit"/>
  <short value="unit"/>
  <definition value="SHALL contain exactly one [1..1] unit (CONF:4383-282)."/>
  <min value="1"/>
  <max value="1"/>
</element>

Sean McIlvenna (Aug 13 2018 at 22:52):

still gives that error...

Sean McIlvenna (Aug 13 2018 at 22:53):

regardless of whether I put <type> on value[x] or value[x].valueQuantity

Lloyd McKenzie (Aug 13 2018 at 22:53):

Why are you slicing by value?

Sean McIlvenna (Aug 13 2018 at 22:53):

oh.. i see what you mean

Sean McIlvenna (Aug 13 2018 at 22:53):

ok, good point. I'll try to change that

Sean McIlvenna (Aug 13 2018 at 22:57):

ok. changed it to slice by "type" with path "$this"

Sean McIlvenna (Aug 13 2018 at 22:57):

same error

Sean McIlvenna (Aug 13 2018 at 23:01):

I keep trying different variations, and nothing is working... =/

Sean McIlvenna (Aug 13 2018 at 23:01):

just trying to figure out how to require .value and .unit on a valueQuantity in an Observation...

Lloyd McKenzie (Aug 13 2018 at 23:03):

What happens in the vital signs profiles?

Eric Haas (Aug 14 2018 at 00:00):

I do not think you are able to slice by anything other that value in the spreadsheets.

Lloyd McKenzie (Aug 14 2018 at 00:04):

You can slice by anything in the spreadsheets. Just append .@type, .@pattern, etc. to your discriminator

Grahame Grieve (Aug 14 2018 at 06:02):

is this sorted?

Sean McIlvenna (Aug 14 2018 at 21:48):

I believe this is a bug in the older version of the ig publisher that I was using... now I'm getting different errors, having downloaded the latest ig publisher

Sean McIlvenna (Aug 14 2018 at 21:48):

will confirm once I know for sure
