Le système de référence spatial n'est pas inclus dans la traduction de la fiche ISO vers le GeoDCAT-AP et le MobilityDCAT-AP

Il est optionnel pour le GeoDCAT-AP mais recommandé pour le MobilityDCAT-AP.

Donc mobility DCAT-AP est une extension de DCAT-AP (cf. https://mobilitydcat-ap.github.io/mobilityDCAT-AP/releases/index.html#specification). D'où https://github.com/SPW-DIG/metawal-core-geonetwork/blob/dcat/schemas/iso19115-3.2018/src/main/plugin/iso19115-3.2018/formatter/eu-dcat-ap-mobility/mobility-dcat-ap-core.xsl#L20

Mais on a "Some of these class and property additions align with the parallel DCAT-AP extension [GEODCAT-AP-v2.0.0], enabling compatibility between the two extensions in terms of class and property additions."

En GeoDCAT-AP on a bien le mapping pour referenceSystem eg.
https://apps.titellus.net/geonetwork/srv/api/records/3e501c87-9146-4d9b-9237-8165c8f7cd51/formatters/eu-geodcat-ap

<dct:type rdf:resource="http://inspire.ec.europa.eu/glossary/SpatialReferenceSystem"/>
</rdf:Description>
</geodcatap:referenceSystem>

Donc en mobilty DCAT l'encodage est différent:

<skos:prefLabel xml:lang="fr">Transports</skos:prefLabel>

</dcat:theme>
<dct:conformsTo>
<dct:Standard rdf:about="http://www.opengis.net/def/crs/EPSG/0/31370"/>
</dct:conformsTo>
<dcat:spatialResolutionInMeters rdf:datatype="http://www.w3.org/2001/XMLSchema#decimal">100</dcat:spatialResolutionInMeters>
<dct:spatial>

j'adapte le mapping. Est-ce qu'il y aurait d'autres propriétés de GeoDCAT "copiées" dans mobility DCAT qu'il faudrait gérer ? @vbombaerts
