1 Introduction (Informative)

This document contains terms that are part of the most recent version of the Darwin Core vocabulary (http://rs.tdwg.org/version/dwc/2023-09-13).

This document includes terms in four namespaces that contain recommended terms: dwc:, dwciri:, dc:, and dcterms:. However, some terms in these namespaces are deprecated or superseded and should no longer be used. Deprecation or supersession is noted in the term metadata. Namespaces that contain only deprecated terms are not included in this document, but metadata about those terms can be retrieved by dereferencing their IRIs.

For a simplified list that contains only the currently recommended terms, see the Darwin Core Quick Reference Guide.

1.1 Status of the content of this document

Sections 1 and 3 are non-normative.

Section 2 is normative.

In Section 4, the values of the Term IRI and Definition are normative. The values of Term Name are non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. Label and the values of all other properties (such as Examples and Notes) are non-normative.

1.2 RFC 2119 key words

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC 2119] and [RFC 8174] when, and only when, they appear in all capitals, as shown here.

1.3 Namespace abbreviations

The following namespace abbreviations are used in this document:

abbreviation	IRI
dwc:	http://rs.tdwg.org/dwc/terms/
dwciri:	http://rs.tdwg.org/dwc/iri/
dc:	http://purl.org/dc/elements/1.1/
dcterms:	http://purl.org/dc/terms/

2 Use of Terms

Due to the requirements of Section 1.4.3 of the Darwin Core RDF Guide, terms in the dwciri: namespace MUST be used with IRI values. Terms in the dwc: and dc: namespaces are generally expected to have string literal values. Values for terms in the dcterms: namespace will depend on the details of the term. See Section 3 of the Darwin Core RDF Guide for details.

4 Vocabulary

Term Name dwc:acceptedNameUsage
Term IRI	http://rs.tdwg.org/dwc/terms/acceptedNameUsage
Modified	2023-06-28
Term version IRI	http://rs.tdwg.org/dwc/terms/version/acceptedNameUsage-2023-06-28
Label	Accepted Name Usage
Definition	The full name, with authorship and date information if known, of the currently valid (zoological) or accepted (botanical) dwc:Taxon.
Notes	The full scientific name, with authorship and date information if known, of the accepted (botanical) or valid (zoological) name in cases where the provided dwc:scientificName is considered by the reference indicated in the dwc:accordingTo property, or of the content provider, to be a synonym or misapplied name. When applied to a dwc:Organism or dwc:Occurrence, this term should be used in cases where a content provider regards the provided dwc:scientificName to be inconsistent with the taxonomic perspective of the content provider. For example, there are many discrepancies within specimen collections and observation datasets between the recorded name (e.g., the most recent identification from an expert who examined a specimen, or a field identification for an observed dwc:Organism), and the name asserted by the content provider to be taxonomically accepted.

Modified	2023-06-28
Term version IRI	http://rs.tdwg.org/dwc/terms/version/associatedReferences-2023-06-28
Label	Associated References
Definition	A list (concatenated and separated) of identifiers (publication, bibliographic reference, global unique identifier, URI) of literature associated with the dwc:Occurrence.
Notes	Recommended best practice is to separate the values in a list with space vertical bar space ( | ). Note that the dwc:ResourceRelationship class is an alternative means of representing associations, and with more detail. Note also that the intended usage of the term dcterms:references in Darwin Core when applied to a dwc:Occurrence is to point to the definitive source representation of that dwc:Occurrence if one is available. Note also that the intended usage of dcterms:bibliographicCitation in Darwin Core when applied to a dwc:Occurrence is to provide the preferred way to cite the dwc:Occurrence itself.

Label	Associated Taxa
Definition	A list (concatenated and separated) of identifiers or names of dwc:Taxon records and the associations of this dwc:Occurrence to each of them.
Notes	This term can be used to provide a list of associations to dwc:Taxon records other than the one defined in the dwc:Occurrence. Note that the dwc:ResourceRelationship class is an alternative means of representing associations, and with more detail. This term is not apt for establishing relationships between dwc:Taxon records, only between specific dwc:Occurrences of a dwc:Organism with other dwc:Taxon records. Recommended best practice is to separate the values in a list with space vertical bar space ( | ).

Label	Bibliographic Citation
Definition	A bibliographic reference for the resource.
Notes	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.

Label	Footprint Spatial Fit
Definition	The ratio of the area of the dwc:footprintWKT to the area of the true (original, or most specific) spatial representation of the dcterms:Location. Legal values are 0, greater than or equal to 1, or undefined. A value of 1 is an exact match or 100% overlap. A value of 0 should be used if the given dwc:footprintWKT does not completely contain the original representation. The dwc:footprintSpatialFit is undefined (and should be left empty) if the original representation is any geometry without area (e.g., a point or polyline) and without uncertainty and the given georeference is not that same geometry (without uncertainty). If both the original and the given georeference are the same point, the dwc:footprintSpatialFit is 1.

Modified	2023-06-28
Term version IRI	http://rs.tdwg.org/dwc/terms/version/nameAccordingTo-2023-06-28
Label	Name According To
Definition	The reference to the source in which the specific taxon concept circumscription is defined or implied - traditionally signified by the Latin "sensu" or "sec." (from secundum, meaning "according to"). For taxa that result from identifications, a reference to the keys, monographs, experts and other sources should be given.
Notes	This term provides context to the dwc:scientificName. Together with the dwc:scientificName, separated by sensu or sec., it forms the taxon concept label, which may be seen as having the same relationship to dwc:taxonConceptID as, for example, dwc:acceptedNameUsage has to dwc:acceptedNameUsageID. When not provided, in Taxon Core data sets the dwc:nameAccordingTo can be taken to be the data set. In this case the data set mostly provides sufficient context to infer the delimitation of the taxon and its relationship with other taxa. In Occurrence Core data sets, when not provided, dwc:nameAccordingTo can be an underlying taxonomy of the data set, e.g. Plants of the World Online (http://powo.science.kew.org/) for vascular plant records in iNaturalist (in which case it should be provided), or, which is the case for most dwc:PreservedSpecimen data sets, the dwc:Identification, in which case there is no further context.

Legal values are 0, greater than or equal to 1, or undefined. A value of 1 is an exact match or 100% overlap. A value of 0 should be used if the given point-radius does not completely contain the original representation. The dwc:pointRadiusSpatialFit is undefined (and should be left empty) if the original representation is any geometry without area (e.g., a point or polyline) and without uncertainty and the given georeference is not that same geometry (without uncertainty). If both the original and the given georeference are the same point, the dwc:pointRadiusSpatialFit is 1.

Label	Recorded By ID
Definition	A list (concatenated and separated) of the globally unique identifier for the person, people, groups, or organizations responsible for recording the original dwc:Occurrence.
Notes	Recommended best practice is to provide a single identifier that disambiguates the details of the identifying agent. If a list is used, it is recommended to separate the values in the list with space vertical bar space ( | ). The order of the identifiers on any list for this term can not be guaranteed to convey any semantics.

Label	References
Definition	A related resource that is referenced, cited, or otherwise pointed to by the described resource.
Notes	From Dublin Core, "This property is intended to be used with non-literal values. 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.

Modified	2023-06-28
Term version IRI	http://rs.tdwg.org/dwc/terms/version/scientificName-2023-06-28
Label	Scientific Name
Definition	The full scientific name, with authorship and date information if known. When forming part of a dwc:Identification, this should be the name in lowest level taxonomic rank that can be determined. This term should not contain identification qualifications, which should instead be supplied in the dwc:identificationQualifier term.
Notes	This term should not contain identification qualifications, which should instead be supplied in the IdentificationQualifier term. When applied to an Organism or Occurrence, this term should be used to represent the scientific name that was applied to the associated Organism in accordance with the Taxon to which it was or is currently identified. Names should be compliant to the most recent nomenclatural code. For example, names of hybrids for algae, fungi and plants should follow the rules of the International Code of Nomenclature for algae, fungi, and plants (Schenzhen Code Articles H.1, H.2 and H.3). Thus, use the multiplication sign × (Unicode U+00D7, HTML ×) to identify a hybrid, not x or X, if possible.
