Notes
For natural history collections baseTypeOfCollection describes types of occurrences and may constrain the values available in objectType. Notes for ObjectGroups where baseTypeOfCollection is 'InformationArtefact': subsequent ‘type’ properties could include hierarchical Audubon Core/Dublin Core terms – e.g. dc:type (http://purl.org/dc/elements/1.1/type), ac:subtype / ac:subtypeLiteral (http://rs.tdwg.org/ac/terms/subtypeLiteral), or (proposed) ac:3DResourceType.
