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/2021-07-15).

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 However, some terms in these namespaces are deprecated or superseded and should no longer be used.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 RFC 2119.

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.

Modified 2021-07-15
Term version IRI http://rs.tdwg.org/dwc/terms/version/acceptedNameUsage-2021-07-15
Label Accepted Name Usage
Definition The full name, with authorship and date information if known, of the currently valid (zoological) or accepted (botanical) 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 scientificName is considered by the reference indicated in the accordingTo property, or of the content provider, to be a synonym or misapplied name. When applied to an Organism or Occurrence, this term should be used in cases where a content provider regards the provided 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 organism), and the name asserted by the content provider to be taxonomically accepted.
Examples Tamias minimus (valid name for Eutamias minimus).

Label Associated References
Definition A list (concatenated and separated) of identifiers (publication, bibliographic reference, global unique identifier, URI) of literature associated with the Occurrence.
Notes Recommended best practice is to separate the values in a list with space vertical bar space ( | ). Note that the 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 an Occurrence is to point to the definitive source representation of that Occurrence if one is available. Note also that the intended usage of dcterms:bibliographicCitation in Darwin Core when applied to an Occurrence is to provide the preferred way to cite the Occurrence itself.

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

Term version IRI http://rs.tdwg.org/dwc/iri/version/earliestGeochronologicalEra-2015-03-27
Label Earliest Geochronological Era
Definition Use to link a dwc:GeologicalContext instance to chronostratigraphic time periods at the lowest possible level in a standardized hierarchy. Use this property to point to the earliest possible geological time period from which the cataloged item was collected.
Notes Recommended best practice is to use an IRI from a controlled vocabulary. A "convenience property" that replaces Darwin Core literal-value terms related to geological context. See Section 2.7.6 of the Darwin Core RDF Guide for details.

Label Footprint Spatial Fit
Definition The ratio of the area of the footprint (footprintWKT) to the area of the true (original, or most specific) spatial representation of the 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 footprint does not completely contain the original representation. The footprintSpatialFit is undefined (and should be left empty) if the original representation is a point without uncertainty and the given georeference is not that same point (without uncertainty). If both the original and the given georeference are the same point, the 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).

Label Footprint SRS
Definition The ellipsoid, geodetic datum, or spatial reference system (SRS) upon which the geometry given in 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.

Modified 2021-07-15
Term version IRI http://rs.tdwg.org/dwc/terms/version/nameAccordingTo-2021-07-15
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 scientificName. Together with the scientificName, separated by ‘sensu’ or ‘sec.’, it forms the taxon concept label, which may be seen as having the same relationship to taxonConceptID as, for example, acceptedNameUsage has to acceptedNameUsageID. When not provided, in Taxon Core data sets the 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, 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 PreservedSpecimen data sets, the Identification, in which case there is no further context.

For example, for names governed by the ICNafp, this term would establish the relationship between a record representing a subsequent combination and the record for its corresponding basionym. Unlike basionyms, however, this term can apply to scientific names at all ranks. For Darwin Core Archives the related record should be present locally in the same archive.

Definition The ratio of the area of the point-radius (decimalLatitude, decimalLongitude, coordinateUncertaintyInMeters) to the area of the true (original, or most specific) spatial representation of the 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 pointRadiusSpatialFit is undefined (and should be left empty) if the original representation is a point without uncertainty and the given georeference is not that same point (without uncertainty). If both the original and the given georeference are the same point, the pointRadiusSpatialFit is 1.

Definition A list (concatenated and separated) of names of people, groups, or organizations responsible for recording the original Occurrence. The primary collector or observer, especially one who applies a personal identifier (recordNumber), should be listed first.
Notes Recommended best practice is to separate the values in a list with space vertical bar space ( | ).
Examples José E. Crespo. Oliver P. Pearson | Anita K. Pearson (where the value in recordNumber OPP 7101 corresponds to the collector number for the specimen in the field catalog of Oliver P. Pearson).

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 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.,Taxon, Occurrence, Event in Darwin Core), 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.
