I am looking for a RDF vocabulary that describes the unit gross tonnage. I have browsed the qudt unit vocabulary without finding the unit I am looking for. Can't seem to find a vocabulary describing gross tonnage when searching around either. Does anyone know a vocabulary I can dive into to find this unit?
If you have not done so, I advise you to search for this term on platforms such as LOV (Linked Open Vocabularies), which allow you to search for vocabularies and terms within vocabularies that are referenced by the platform.
By searching gross tonnage you will have a few hits such as GrossWeightCharacteristic, the "Gross weight characteristic of a vehicle" (but I couldn't tell if it's really what you need).
There is other plateforms allowing to search for terms in vocabularies, such as OntoBee, the EMBL-EBI Ontology Lookup Service (for biomedical ontologies) or the MMI Ontology Registry and Repository (ORR) (for marine science).
