Darwin Core クイックリファレンスガイド

This document is intended to be an easy-to-read reference of the currently (as of 2023-09-18) recommended terms maintained as part of the Darwin Core standard and is maintained by the Darwin Core Maintenance Group.

Need help? Read more about how to use Darwin Core in the Darwin Core Questions & Answers site. Still have questions? Submit a new issue (question/problem) to the dwc-qa issues page in GitHub, or use the form. See the bottom of this document for how to cite Darwin Core.”

This page is not part of the standard, but combines the normative term names and definitions with the non-normative comments and examples that are meant to help people to use the terms consistently. Definitions, comments, and examples may include namespace abbreviations (e.g., “dwc:”). These are included to show that the meaning for the word it is attached to very specifically means the term as defined in that namespace. Thus, dwc:Event means Event as defined by Darwin Core at https://dwc.tdwg.org/terms/#event. Capitalized terms that follow a namespace abbreviation, such as dwc:Occurrence, are Darwin Core class terms, which are a special category of terms used to group sets of property terms (terms that being with lower case names that follow the namespace abbreviation, e.g., dwc:eventID) for convenience. Comprehensive metadata for current and obsolete terms in human readable form are found in the document List of Darwin Core terms.

Additional files with just the current term names and a file with the full term history can be found in the Darwin Core repository.

レコードレベル

This category contains terms that are generic in that they might apply to any type of record in a dataset.

type
識別子	http://purl.org/dc/elements/1.1/type
定義	The nature or genre of the resource.
備考	Must be populated with a value from the DCMI type vocabulary (https://www.dublincore.org/specifications/dublin-core/dcmi-type-vocabulary/2010-10-11/).

備考	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.
例	`Museum of Vertebrate Zoology, UC Berkeley. MVZ Mammal Collection (Arctos). Record ID: http://arctos.database.museum/guid/MVZ:Mamm:165861?seid=101356.

識別子	http://rs.tdwg.org/dwc/terms/scientificName
定義	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.
備考	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.
例	`Coleoptera` (order) `Vespertilionidae` (family) `Manis` (genus) `Ctenomys sociabilis` (genus + specificEpithet) `Ambystoma tigrinum diaboli` (genus + specificEpithet + infraspecificEpithet) `Roptrocerus typographi (Györfi, 1952)` (genus + specificEpithet + scientificNameAuthorship) `Quercus agrifolia var. oxyadenia (Torr.)

備考	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:nameAccordingTo 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.
例	`Tamias minimus` (valid name for `Eutamias minimus`)

備考	The full scientific name, with authorship and date information if known, of the name usage in which the terminal element of the dwc:scientificName was originally established under the rules of the associated dwc:nomenclaturalCode. For example, for names governed by the ICNafp, this term would indicate the basionym of a record representing a subsequent combination. Unlike basionyms, however, this term can apply to scientific names at all ranks.
例	`Pinus abies` `Gasterosteus saltatrix Linnaeus 1768`

nameAccordingTo
識別子	http://rs.tdwg.org/dwc/terms/nameAccordingTo
定義	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.
備考	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.
