dcterms [dcterms] namespace descriptor quick reference guide
Darwin Core is a standard maintained by the Darwin Core Maintenance Interest Group. The Darwin Core vocabulary including classes and their properties have been fully implemented on ther EU Pollinator Hub vocabulary. Terms in the namespace abbreviation dcterms: are imports of Dublin Core terms from the /terms/ namespace into the Darwin Core vocabulary for use in describing biodiversity data. The Dublin Core namespace URI these terms is: http://purl.org/dc/terms/

- the place defined by a georeference
Access Rights may include information regarding access or restrictions based on privacy, security, or other policies.

From Dublin Core, "Recommended practice is to include sufficient bibliographic detail to identify the resource as unambiguously as possible." The intended usage of this term in Darwin Core is to provide the preferred way to cite the resource itself - "how to cite this record". Note that the intended usage of dcterms:references in Darwin Core, by contrast, is to point to the definitive source representation of the resource - "where to find the as-close-to-original reference", if one is available.

This property is an inverse property of Is Referenced By." the intended usage of this term in Darwin Core is to point to the definitive source representation of the resource (e.g.,dwc:Taxon, dwc:Occurrence, dwc:Event), if one is available. Note that the intended usage of dcterms:bibliographicCitation in Darwin Core, by contrast, is to provide the preferred way to cite the resource itself.
