dcat:CatalogRecord should always have a foaf:primaryTopic

[NielsHoffmann]

This is an issue for the GeoDCAT-AP 3.0.0 pilot.

According to the Application profile a dcat:CatalogRecord should always point to a dcat:Resource.
https://semiceu.github.io/GeoDCAT-AP/releases/3.0.0/#CatalogueRecord
this is also reflected in the shacl profile:

<https://semiceu.github.io/GeoDCAT-AP/releases/3.0.0#dcat:CatalogRecordShape/65eafe0643a998b84fc2d253de401f9ad8355770> rdfs:seeAlso "https://semiceu.github.io/GeoDCAT-AP/releases/3.0.0#CatalogueRecord.primarytopic";
  shacl:description "A link to the Dataset, Data service or Catalog described in the record."@en;
  shacl:minCount 1;
  shacl:name "primary topic"@en;
  shacl:path foaf:primaryTopic .

<https://semiceu.github.io/GeoDCAT-AP/releases/3.0.0#dcat:CatalogRecordShape/c65d45ed7195ead5f643ec8c8afd29c6dd9662bf> rdfs:seeAlso "https://semiceu.github.io/GeoDCAT-AP/releases/3.0.0#CatalogueRecord.primarytopic";
  shacl:class dcat:Resource;
  shacl:description "A link to the Dataset, Data service or Catalog described in the record."@en;
  shacl:name "primary topic"@en;
  shacl:path foaf:primaryTopic .

The XSLT creates a CatalogRecord for the new DCAT record which points (in this example) properly to the Dataset:

<foaf:isPrimaryTopicOf>
         <rdf:Description>
            <rdf:type rdf:resource="http://www.w3.org/ns/dcat#CatalogRecord"/>
            <foaf:primaryTopic rdf:resource="https://services.rce.geovoorziening.nl/www/download/e39bd6e0-7651-11e0-a1f0-0800200c9a62"/>
            <dct:conformsTo>
               <dct:Standard rdf:about="http://data.europa.eu/930/"/>
            </dct:conformsTo>
...

The XSLT also creates a 'dct:source' CatalogRecord stating that the new (converted) record has a iso-19115 source.
However, this source record, being a dcat:CatalogRecord should contain a foaf:primaryTopic according to the profile and the Shacl file

 <dct:source rdf:parseType="Resource">
               <rdf:type rdf:resource="http://www.w3.org/ns/dcat#CatalogRecord"/>
               <dct:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#date">2024-09-27</dct:modified>
               <cnt:characterEncoding rdf:datatype="http://www.w3.org/2001/XMLSchema#string">UTF-8</cnt:characterEncoding>
               <dct:conformsTo rdf:parseType="Resource">
                  <rdf:type rdf:resource="http://purl.org/dc/terms/Standard"/>
                  <dct:title xml:lang="nl">ISO 19115</dct:title>
                  <owl:versionInfo xml:lang="nl">Nederlands metadata profiel op ISO 19115 voor geografie 2.1.0</owl:versionInfo>
               </dct:conformsTo>
            </dct:source>

The shacl file tests for dcat:Resource, so for the XSLT to conform to the shacl profile, the dcat:Dataset should also be typed as dcat:Resource.
