language
識別子	http://purl.org/dc/elements/1.1/language
定義	A language of the resource.
備考	Recommended best practice is to use a controlled vocabulary such as RFC 5646. This term has an equivalent in the dcterms: namespace that allows only an IRI as a value, whereas this term allows for any string literal value.
例	`en` (for English) `es` (for Spanish)

license
識別子	http://purl.org/dc/terms/license

bibliographicCitation
識別子	http://purl.org/dc/terms/bibliographicCitation
定義	A bibliographic reference for the resource.
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. Source: http://ipt.vertnet.org:8080/ipt/resource.do?r=mvz_mammal.` (Occurrence example) `https://www.gbif.org/species/2439608 Source: GBIF Taxonomic Backbone` (Taxon example) `Rand, K.M., Logerwell, E.A.

識別子	http://purl.org/dc/terms/references
定義	A related resource that is referenced, cited, or otherwise pointed to by the described resource.
備考	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.
例	`http://arctos.database.museum/guid/MVZ:Mamm:165861` (MaterialEntity example) `https://www.catalogueoflife.org/data/taxon/32664 (Taxon example)`

識別子	http://rs.tdwg.org/dwc/terms/associatedReferences
定義	A list (concatenated and separated) of identifiers (publication, bibliographic reference, global unique identifier, URI) of literature associated with the dwc:Occurrence.
備考	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.

MaterialEntity クラス
識別子	http://rs.tdwg.org/dwc/terms/MaterialEntity
定義	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.
備考	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. In Darwin Core, dwc:Organism, dwc:Occurrence, and dwc:MaterialEntity are related, but distinct concepts. A dwc:Organism is a biological individual or group with an identity and life history that persists independently of the particular dwc:MaterialEntities through which it is manifested. A dwc:Occurrence is a dwc:Event that represents the presence or state of a dwc:Organism at a place during an interval of time, with no explicit dependency on any dwc:MaterialEntity. A dwc:MaterialEntity represents physical matter, including whole bodies, parts, or derivatives of dwc:Organisms, that may directly or indirectly serve as evidence of a dwc:Occurrence.
例	`the entire contents of a trawl` `a subset of the contents of a trawl` `the body of a fish` `the stomach contents of a fish` `a rock containing fossils` `a fossil within a rock` `an herbarium sheet with its attached plant specimen` `a flower on a plant specimen` `a pollen grain` `a specific water sample` `an isolated molecule of DNA`

materialEntityID
識別子	http://rs.tdwg.org/dwc/terms/materialEntityID
定義	An identifier for a particular instance of a dwc:MaterialEntity.
備考	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.
例	`06809dc5-f143-459a-be1a-6f03e63fc083`

digitalSpecimenID
識別子	http://rs.tdwg.org/dwc/terms/digitalSpecimenID
定義	An identifier for a Digital Specimen resource.
備考	A Digital Specimen is defined in https://doi.org/10.3897/rio.7.e67379. A dwc:digitalSpecimenID is intended to uniquely and persistently identify a Digital Specimen. Recommended best practice is to use a DOI with machine readable metadata in the DOI record that uses a community agreed metadata profile (also known as FDO profile) for a Digital Specimen. For an example see: https://doi.org/10.3535/N75-CR4-0SM?noredirect. The identifier is for a digital information artifact (the Digital Specimen) as opposed to an identifier for a specific instance of a dwc:MaterialEntity.
例	`https://doi.org/10.3535/M42-Z4P-DRD` `https://doi.org/10.3535/M42-Z4P-DRD?urlappend=/1` `https://doi.org/10.3535/M42-Z4P-DRD?locatt=/1` `doi:10.3535/M42-Z4P-DRD`

materialEntityCategory
識別子	http://rs.tdwg.org/dwc/terms/materialEntityCategory
定義	A high-level, mutually exclusive classification describing the fundamental substance and origin of a dwc:MaterialEntity.

This term has an equivalent in the dwciri: namespace that allows only an IRI as a value, whereas this term allows for any string literal value.
例	`Botany` `Botany \| Virology \| Taxonomy`

typeOfType
識別子	http://rs.tdwg.org/dwc/terms/typeOfType
定義	A category of nomenclatural type of a dwc:MaterialEntity.
備考	The term dwc:typeOfType must be used in combination with dwc:typifiedName. Together they make up the type status of a specimen. Note that relatively very few specimens are nomenclatural types (types of names), so in most cases this term will have no value. Unlike dwc:typeStatus, dwc:typeOfType can only have a single value. Recommended best practice is to use a controlled vocabulary such as the GBIF Nomenclatural Type Status Vocabulary. This term has an equivalent in the tcs: namespace that allows only an IRI as a value, whereas this term allows for any string literal value.
例	`holotype` `isotype`

typifiedName
識別子	http://rs.tdwg.org/dwc/terms/typifiedName
定義	A scientific name for which a specimen or other name is the type.
備考	The term dwc:typifiedName must be used in combination with dwc:typeOfType. Together they make up the type status of a specimen. Note that relatively very few specimens are nomenclatural types (types of names), so in most cases this term will have no value. Unlike dwc:typeStatus, dwc:typifiedName can only have a single value, so a dwc:MaterialEntity can only have a single dwc:typifiedName.

Occurrence クラス
識別子	http://rs.tdwg.org/dwc/terms/Occurrence
定義	A dwc:Event that establishes the state of a dwc:Organism at a particular place and time.
備考	In Darwin Core, dwc:Organism, dwc:Occurrence, and dwc:MaterialEntity are related, but distinct concepts. A dwc:Organism is a biological individual or group with an identity and life history that persists independently of the particular dwc:MaterialEntities through which it is manifested. A dwc:Occurrence is a dwc:Event that represents the presence or state of a dwc:Organism at a place during an interval of time, with no explicit dependency on any dwc:MaterialEntity. A dwc:MaterialEntity represents physical matter, including whole bodies, parts, or derivatives of dwc:Organisms, that may directly or indirectly serve as evidence of a dwc:Occurrence.

Organism クラス
識別子	http://rs.tdwg.org/dwc/terms/Organism
定義	A particular organism or defined group of organisms considered to be taxonomically homogeneous.
備考	Instances of the dwc:Organism class are intended to facilitate linking one or more dwc:Identification instances to one or more dwc:Occurrence instances. Therefore, things that are typically assigned scientific names (such as viruses, hybrids, and lichens) and aggregates whose dwc:Occurrences are typically recorded (such as packs, clones, and colonies) are included in the scope of this class. In Darwin Core, dwc:Organism, dwc:Occurrence, and dwc:MaterialEntity are related, but distinct concepts. A dwc:Organism is a biological individual or group with an identity and life history that persists independently of the particular dwc:MaterialEntities through which it is manifested. A dwc:Occurrence is a dwc:Event that represents the presence or state of a dwc:Organism at a place during an interval of time, with no explicit dependency on any dwc:MaterialEntity.

    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.
    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 (Shenzhen 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.

    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.

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. Use dwc:verbatimIdentification for the full name string used in a dwc:Identification.
