Sources to characterize a power plant
List of ontologies used to reference power plant types:
* Wikidata * DBpedia * Open Energy Ontology * EuroVoc * GEMET * [FAO]
This example compares different definitions of hydropower plants provided by various ontologies/controlled vocabularies:
* wikidata:Q1591738: literal name: hydroelectric power station definition: facility generating electric power using hydroelectricity
* oeo:OEO_00010086: literal name: hydro power plant definition: A hydro power plant is a power plant having an aggregate of hydro power generating units as its power generating unit parts.
* [GEMET gemet:4098]: literal name: hydroelectric power plant definition: Power station which operates with the free renewable source of energy provided by falling water.
Note, that dbpedia and EuroVoc do not provide a resource specifically describing a hydropower plant. They rather offer definitions on the general concept of hydropower technology.
