US_UtilityNetwork_authorityRole RelatedParty type to reference inline

[mquanz]

Change proposal description

In the "UtilityNetwork" FeatureType (application scheme "Common Utility Network Elements") the data type of "authorityRole" is defined by the implementation rules and INSPIRE model as "RelatedParty". This is implemented in the INSPIRE schema XSD in form of a gml:ReferenceType.

Extract from the XSD:
<element maxOccurs="unbounded" name="authorityRole" type="gml:ReferenceType">

However a reference can only be set to a feature type, not to a data type. As it is not possible to create a RelatedParty object on top level in a gml:FeatureCollection, this is indeed a problem.

I suggest to change the schema that RelatedParty objects can be created inline.

Issue faced

RelatedParty objects cannot be referenced.

Expected behaviour

RelatedParty objects can be created inline.

Current behaviour

RelatedParty objects cannot be referenced.

Proposed solution

I suggest to change the schema that RelatedParty objects can be created inline.

Dear @mquanz,

thank you for opening the issue.
It seems that the datatype of the "authorityRole" attribute is not correct.
We will have a look asap.

Just adding details of required schema change:
current definition
<element maxOccurs="unbounded" name="authorityRole" type="gml:ReferenceType">
should be replaced by

<element maxOccurs="unbounded" name="authorityRole">
         <complexType>
            <sequence>
              <element ref="base2:RelatedParty"/>
            </sequence>
         </complexType>
  </element>
