MD_Keywords to dcat:theme transformation is incomplete

[NielsHoffmann]

I'm looking into the transformation of MD_Keywords to dcat:theme for the Geodcat ap 3.0.0 pilot.

Looking into the xsl it is clear a lot of logic is commented out in this specific part of the file, so the authors are no doubt well aware of the challenges... Nevertheless I would like to log an issue for the pilot on this topic.

We have the following snippet in one of our reference iso-19115 xml files:

<gmd:descriptiveKeywords>
        <gmd:MD_Keywords>
          <gmd:keyword>
            <gmx:Anchor xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.eionet.europa.eu/gemet/nl/inspire-theme/ps">Beschermde gebieden</gmx:Anchor>
          </gmd:keyword>
          <gmd:type>
            <gmd:MD_KeywordTypeCode codeList="http://schemas.opengis.net/iso/19139/20060504/resources/Codelist/gmxCodelists.xml#MD_KeywordTypeCode" codeListValue="theme">theme</gmd:MD_KeywordTypeCode>

                  </gmd:dateType>
                </gmd:CI_Date>
              </gmd:date>
              <gmd:identifier>
                <gmd:MD_Identifier>
                  <gmd:code>
                    <gmx:Anchor xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="https://www.nationaalgeoregister.nl/geonetwork/srv/api/registries/vocabularies/external.theme.httpinspireeceuropaeutheme-theme">geonetwork.thesaurus.external.theme.httpinspireeceuropaeutheme-theme</gmx:Anchor>
                  </gmd:code>
                </gmd:MD_Identifier>
              </gmd:identifier>
            </gmd:CI_Citation>
          </gmd:thesaurusName>
        </gmd:MD_Keywords>
      </gmd:descriptiveKeywords>

The current (enabled) logic in the xsl transforms this into:

<dcat:theme rdf:resource="http://www.eionet.europa.eu/gemet/nl/inspire-theme/ps"/>

This feels like a severe loss of information.

• the dutch label "Beschermde gebieden" is missing
• the documentation on the used vocabulary and the datestamp of this controlled vocabulary is also missing
