List of Darwin Core terms. Biodiversity Information Standards (TDWG). ## 1 Introduction (Informative) This document contains terms that are part of the most recent version of the Darwin Core vocabulary (). 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 However, some terms in these namespaces are deprecated or superseded and should no longer be used.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](../terms/). ### 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 [RFC 2119](https://tools.ietf.org/html/rfc2119). ### 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](../rdf/#143-use-of-darwin-core-terms-in-rdf-normative), 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](../rdf/#3-term-reference-normative) for details. ## 3 Term indices ### 3.1 Index By Term Name (See also [3.2 Index By Label](#32-index-by-label))

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.

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.

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.

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.
Notes Detailed explanations with graphical examples can be found in the Georeferencing Best Practices, Chapman and Wieczorek, 2020 (https://doi.org/10.15468/doc-gg7h-s853).

Definition The ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geometry given in dwc:footprintWKT is based.
Notes Recommended best practice is to use the EPSG code of the SRS, if known. Otherwise use a controlled vocabulary for the name or code of the geodetic datum, if known. Otherwise use a controlled vocabulary for the name or code of the ellipsoid, if known. If none of these is known, use the value unknown. It is also permitted to provide the SRS in Well-Known-Text, especially if no EPSG code provides the necessary values for the attributes of the SRS. Do not use this term to describe the SRS of the dwc:decimalLatitude and dwc:decimalLongitude, nor of any verbatim coordinates - use the dwc:geodeticDatum and dwc:verbatimSRS instead.

Label Infraspecific Epithet
Definition The name of the lowest or terminal infraspecific epithet of the dwc:scientificName, excluding any rank designation.
Notes In botany, name strings in literature and identifications may have multiple infraspecific ranks. According to the International Code of Nomenclature for algae, fungi, and plants (Schenzhen Code Articles 6.7 & Art. 24.1), valid names only have two epithets, with the lowest rank being the dwc:infraspecificEpithet. For example: the dwc:infraspecificEpithet in the string Indigofera charlieriana subsp. sessilis var. scaberrima is scaberrima and the dwc:scientificName is Indigofera charlieriana var. scaberrima (Schinz) J.B.Gillett. Use dwc:verbatimIdentification for the full name string used in a dwc:Identification.
Examples
  • concolor (for scientificName Puma concolor concolor (Linnaeus, 1771))
  • oxyadenia (for scientificName Quercus agrifolia var. oxyadenia (Torr.) J.T. Howell)
  • laxa (for scientificName Cheilanthes hirta f. laxa (Kunze) W.Jacobsen & N.Jacobsen)

Label Material Entity
Definition An entity that can be identified, exists for some period of time, and consists in whole or in part of physical matter while it exists.
Notes The term is defined at the most general level to admit descriptions of any subtype of material entity within the scope of Darwin Core. In particular, any kind of material sample, preserved specimen, fossil, or exemplar from living collections is intended to be subsumed under this term.
Examples
  • an instance of a fossil
  • an instance of a herbarium sheet with its attached plant specimen
  • a particular part of the plant-derived material affixed to a herbarium sheet
  • an instance of a frozen tissue sample
  • a specific water sample
  • an instance of a meteorite fragment
  • a particular wolf in a zoo

Label Material Entity ID
Definition An identifier for a particular instance of a MaterialEntity.
Notes Values of dwc:materialEntityID are intended to uniquely and persistently identify a particular dwc:MaterialEntity within some context. Examples of context include a particular sample collection, an organization, or the worldwide scale. Recommended best practice is to use a persistent, globally unique identifier. The identifier is bound to a physical object (the dwc:MaterialEntity) as opposed to a particular digital record (representation) of that physical object.

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.

Label Point Radius Spatial Fit
Definition The ratio of the area of the point-radius (dwc:decimalLatitude, dwc:decimalLongitude, dwc:coordinateUncertaintyInMeters) 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 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.

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.

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.
