Which code in code_string symbol for DV_ORDINAL?

Technical (archive)

I'm wondering how to set code_string value for a DV_ORDINAL.

Having a DV_ORDINAL a structure like this:
<items archetype_node_id="at0004.1" xsi:type="ELEMENT">
<name>
<value>Element name</value>
</name>
<value xsi:type="DV_ORDINAL">
<value>5</value>
<symbol>
<value>Description 5</value>
<defining_code>
<terminology_id>
<value>local</value>
</terminology_id>
<code_string>???</code_string>
</defining_code>
</symbol>
</value>
</items>

which information should I use in code_string of DV_ORDINAL element? The integer value or the atxxxx
code?

For example, if I defined an ordinal element as
ELEMENT[at0004.1] occurrences matches {0..1} matches { -- Igiene Personale
     value matches {
         5|[local::at0.15], -- Description 5
         4|[local::at0.14], -- Description 4
         3|[local::at0.13], -- Description 3
         2|[local::at0.12], -- Description 2
         1|[local::at0.11] -- Description 1
     }
}

has code_string to be set with at0.1x codes or with integer values (1, 2, 3, 4, 5)?

Thanks for your help!
Regards

Leonardo,

In this case, since terminology_id = ‘local’, code_string will be some string like ‘at0.13’ (based on your extract below). If the terminology_id had been SNOMEDCT_2009_01_01 then code_string has to be a SNOMED CT code… and so on.

Thank you Thomas,
I have clear how to use terminology_id and code for DV_CODED_TEXT, but here
I'm wondering if I can use the ordinal (integer) value as coded value in a
DV_ORDINAL, like in this example (note: <code_string>5</code_string>):

<items archetype_node_id="at0004.1" xsi:type="ELEMENT">
  <name>
    <value>Element name</value>
  </name>
  <value xsi:type="DV_ORDINAL">
    <value>5</value>
    <symbol>
    <value>Description 5</value>
    <defining_code>
      <terminology_id>
        <value>local</value>
      </terminology_id>
      <code_string>5</code_string>
    </defining_code>
    </symbol>
  </value>
</items>

No, Leonardo, you can't do that. The ordinal's value and the code
string are different things. The code string must be a member of the
terminology. In your example, the terminology is "local", which means
that it's an at-code.

Imagine that the coded text used a different terminology. Imagine that
this terminology had codes like "1", "2", "3", "4", "5", etc. If this
was your terminology, then of course your code string could be "5".

Hi Leonardo,

You can use a local terminology-id but do not use ‘local’ for the terminology name, which is reserved name meaning that internal atcodes are being used.

So this would be valid, I think …

<terminology_id>
leonardoCT
</terminology_id>
<code_string>5</code_string>
