extend query to data.europa.eu to include all esdac results

[pvgenuchten]

by filtering on organisation, not just keyword=soil

[pvgenuchten]

esdac records have a property

dct:isPartOf               <https://data.jrc.ec.europa.eu/collection/esdac>

I extended the filter to include records of this collection

---

Unfortunately this property is not indexed by data.europa.eu

instead the emailaddress of the contact point can be used to filter?
mail:ec-esdac@ec.europa.eu

alternative: consider to index the dcat source or continue to work with the indexed properties only
