== Organizational Hierarchy == | |||
In the GeoKB, we use the inverse properties [[Property:P189|has subsidiary]] and [[Property:P190|is subsidiary of]] to describe the relationships between organizational entities like those in the USGS that are organized into a hierarchy. These can be used with SPARQL to construct a graph. | |||
