GE-core_Borehole.boreholeLength_no nilReason attribute provided

[JohannaOtt]

Hi,

Borehole.boreholeLength is using the stereotype voidable according to the implementing rules and the UML model. In the xsd, it is defined using the swe:QuantityPropertyType and no additional attributes which leads to the fact that no nilReason attribute can be provided for Borehole.boreholeLength. Is there a reason not to use a type extending the swe:QuantityPropertyType with an additional nilReason attribute for the boreholeLength element?

Thank you and all the best

Johanna

Dear @JohannaOtt,

no, there is not, it seems that the Borehole.boreholeLength attribute is not encoded correctly. I will move the issue to the schema repository since the encoding should be fixed.

The current encoding:

<element name="boreholeLength" nillable="true" type="swe:QuantityPropertyType">
   <annotation>
      <documentation>-- Definition --The distance along a borehole.-- Description --This
         will be determined by the data provider (ie, "length" can have different sources,
         like drillers measurement, loggers measurement, survey). 
     </documentation>
   </annotation>
</element>

should be replaced by the following:

<element name="boreholeLength" nillable="true">
  <annotation>
    <documentation>-- Definition -- The distance along a borehole. -- Description -- This
      will be determined by the data provider (ie, "length" can have different sources,
      like drillers measurement, loggers measurement, survey).</documentation>
  </annotation>
  <complexType>
    <complexContent>
      <extension base="gml:AbstractMemberType">
        <sequence>
          <element ref="swe:Quantity"/>
        </sequence>
        <attribute name="nilReason" type="gml:NilReasonType"/>
      </extension>
    </complexContent>
  </complexType>
</element>

As shown in the figure below, the new encoding (on the left side) allows the provision of the nilReason.

@fabiovinci Thanks for the quick check and fix!
