MineralResources sourceReference problem

[CLinGBA]

Dear all,

There seems to be an issue with EarthResource and the sourceReference element in MineralResources, defined in the UML as: sourceReference: DocumentCitation[1..*]

In the XSD, the reference to the DocumentCitation dataType gets lost (only mentioned in the appinfo tag), while the xlinks provided via the gml:AssociationAttributeGroup aren't of help as DocumentCitation is a dataType, thus cannot be referenced.

This is an issue, as we thus cannot provide this mandatory information. XSD Snippet showing the issue below

<element name="sourceReference" nillable="true" maxOccurs="unbounded"> <annotation> <documentation>-- Definition -- The source or reference for the Earth Resource.</documentation> <appinfo> <targetElement xmlns="http://www.opengis.net/gml/3.2">base2:DocumentCitation</targetElement> </appinfo> </annotation> <complexType> <complexContent> <extension base="gml:AbstractMemberType"> <sequence/> <attributeGroup ref="gml:AssociationAttributeGroup"/> </extension> </complexContent> </complexType> </element>

Many thanks,

Christian

Hi Christian,

There was a discussion on this in the INSPIRE Forum back in the days https://wayback.archive-it.org/12090/20210123101226/https://inspire.ec.europa.eu/forum/discussion/view/269595/mineraloccurencesourcereference-does-not-allow-inline-creation-of-documentcitation
Kathi wanted to forward the issue to the JRC.

All the best

Johanna

Dear @CLinGBA
bugs in current version of INSPIRE schemas (as well as change proposals) should now be reported via the issue tracker of the application-schemas github repository using the New issue template.
Once this is done, the change proposal (in this case the bug-fixing proposal) will follow the specific governance and release process for INSPIRE schemas described in this document and, if endorsed, will be carried out and lead to a new schema version.
I am now moving this issue to abovementioned application-schemas repository.
In order to help the governance and release process move forward, please copy/paste below and fill in the change proposal template to the best of your knowledge.
Thank you

MR_EarthResource_sourceReference_doesn't_link_to_DocumentCitation

Change proposal description

Update the XSD so that the reference to the DocumentCitation dataType is contained in sourceReference of EarthResource and derived types as foreseen in the UML model

Issue faced

As the sequence provided under sourceReference doesn't contain DocumentCitation, this information cannot be provided inline.
In the XSD, there is a gml:AssociationAttributeGroup providing xlinks, however, DocumentCitation is a dataType, thus cannot be referenced.
As sourceReference is mandatory, this means it is not possible to provide valid data in featureTypes based on EarthResource

Expected behaviour

It should be possible to provide a DocumentCitation inline as foreseen by the model

Current behaviour

It is not possible to provide a DocumentCitation inline as foreseen by the model

Steps to reproduce

Try and provide EarthResource including sourceReference

Proposed solution

Fix the empty sequence currently under sourceReference by adding DocumentCitation - currently just <sequence/>

Technical details

`

<annotation> 

    <documentation>-- Definition -- The source or reference for the Earth Resource.</documentation> 

    <appinfo> <targetElement xmlns="http://www.opengis.net/gml/3.2">base2:DocumentCitation</targetElement> </appinfo> 

</annotation> 

<complexType> 

    <complexContent> 

        <extension base="gml:AbstractMemberType"> 

            <sequence/> 

            <attributeGroup ref="gml:AssociationAttributeGroup"/> 

        </extension> 

    </complexContent> 

</complexType>

Additional information

Proposal reason

This is a bug, and hinders provision of valid information utilizing the EarthResource featureType

Addressed schema

Impact on INSPIRE TG / IR

Makes it possible to fulfill the TG/IR Requirements

Dear @CLinGBA , @KathiSchleidt
could one of you provide a pull request with changes to the schema?
Thank you

[KathiSchleidt]

Hiya,
now fixed the schema, replaced

<sequence minOccurs="0">
	<element ref="swe:Category"/>
</sequence>

with

<sequence minOccurs="0">
	<element ref="base2:DocumentCitation"/>
</sequence>

Does the trick

[sMorrone]

@kathi,
I think you meant you replaced
<sequence/>
i.e the empty sequence tag with

<sequence minOccurs="0">
  <element ref="base2:DocumentCitation"/>
</sequence>

am I right?

[KathiSchleidt]

Sorry, my mistake! Thanks for the correction
