contains A thing spatially contains another thing. This is used to specify a polygon (i.e., an individual of the class `sf:Polygon`) defining the geographical box related to the resource under consideration. The actual value of the polygon can be defined by means of the property `geo:asWKT`, which allows the specification of the coordinates related with the polygon. :my-dataset-location geo:hasGeometry :my-dataset-location-polygon . :my-dataset-location-polygon a sf:Polygon ; geo:asWKT "POLYGON ((30 10, 40 40, 20 40, 30 10))"^^geo:wktLiteral ; geo:sfContains :inner-point . :inner-point a geo:Geometry ; geo:asWKT "POINT(20 20)"^^geo:wktLiteral .
