<rdfs:comment>An extension to [GeoSPARQL](http://www.opengeospatial.org/standards/geosparql) with new features for the representation of additional elements of feature geometry, such as spatial-resolution, length, area and volume. </rdfs:comment>
<skos:editorialNote>The specific elements of this ontology have been created to facilitate use cases generated by the [LocI project](http://loci.cat).These elements will be submitted for consideration for future editions of the GeoSPARQL ontology.</skos:editorialNote>

<skos:editorialNote>This property is not needed - it is not a true sub-property, it is a rule to infer overlap from the existence of a common contained feature ... it is actually more like a record of the _provenance_ of an sfOverlaps property.
