PREFIX dcat: <>
SELECT ?dataset
?dataset dcat:theme <> .
} LIMIT 100
Get the creator(s) of a dataset, and use a federated query to get the name from EDMO
PREFIX dcat: <>

SELECT ?creator ?edmoName WHERE {
<> dcat:creator ?creator
?creator <> ?edmoName .
} LIMIT 1000
Get datasets created by IFREMER (EDMO nr. 486)
PREFIX dcat: <>
SELECT ?dataset
?dataset dcat:creator <> .
} LIMIT 100
Get datasets within polygon (Bounding box around the Netherlands)
PREFIX geo: <>
PREFIX geof: <>
SELECT ?dataset
?dataset geo:hasGeometry ?geometry .
?geometry geo:asWKT ?wkt .
FILTER (geof:sfWithin(?wkt, "POLYGON((3.0 50.5, 7.0 50.5, 7.0 53.5, 3.0 53.5, 3.0 50.5))"^^geo:wktLiteral))
