### 3.4 Terms defined by Darwin Core that are expected to be used only with literal values (normative)
Darwin Core term | Notes on expressing as RDF
--- | ---
dwc:eventDate</br>dwc:georeferencedDate</br>dwc:dateIdentified</br>dwc:relationshipEstablishedDate</br>dwc:measurementDeterminedDate | These date terms have range ```rdfs:Literal```[^8]. Best practice as specified in the term definition recommends that they should be formatted according to [ISO 8601:2004(E)](https://en.wikipedia.org/wiki/ISO_8601). There is no defined [XML Schema datatype](https://www.w3.org/TR/xmlschema11-2/) that corresponds exactly to ISO 8601:2004(E), therefore the entire set of possible values cannot be specified using an ```rdf:datatype``` attribute. The [XML Schema dateTime datatype](https://www.w3.org/TR/xmlschema11-2/#dateTime) (```xsd:dateTime```) which is effectively a subset of ISO 8601:2004(E), may be used as an ```rdf:datatype``` attribute. However, ```xsd:dateTime``` requires the complete series of year, month, day, hour, second (e.g., 002-10-10T12:00:00) and does not permit listing only part of this hierarchy (e.g., only the year) as is allowed in ISO 8601:2004(E).
dwc:eventDate</br>dwc:georeferencedDate</br>dwc:dateIdentified</br>dwc:relationshipEstablishedDate</br>dwc:measurementDeterminedDate | These date terms have range ```rdfs:Literal```<sup>8</sup>. Best practice as specified in the term definition recommends that they should be formatted according to [ISO 8601:2004(E)](https://en.wikipedia.org/wiki/ISO_8601).

dwc:eventTime | It is recommended that the format described by [ISO 8601:2004(E)](https://en.wikipedia.org/wiki/ISO_8601) be used. As with the date terms, there is no [XML Schema datatype](https://www.w3.org/TR/xmlschema11-2/) that includes all of the possible values allowed in ISO 8601:2004(E), so there is no generic ```rdf:datatype``` attribute that would apply to all possible instances. The [XML Schema dateTime datatype](https://www.w3.org/TR/xmlschema11-2/#dateTime) (```xsd:time```) which is effectively a subset of ISO 8601:2004(E) may be used as an ```rdf:datatype``` attribute although it is limited to values that include hours, minutes, and seconds (e.g., 13:07:56-05:00).
dwc:individualCount</br>dwc:decimalLatitude</br>dwc:decimalLongitude</br>dwc:coordinatePrecision</br>dwc:pointRadiusSpatialFit</br>dwc:coordinateUncertaintyInMeters</br>dwc:minimumElevationInMeters</br>dwc:maximumElevationInMeters</br>dwc:minimumDepthInMeters</br>dwc:maximumDepthInMeters</br>dwc:minimumDistanceAboveSurfaceInMeters</br>dwc:maximumDistanceAboveSurfaceInMeters</br>dwc:startDayOfYear</br>dwc:endDayOfYear</br>dwc:year</br>dwc:month</br>dwc:day</br>dwc:footprintSpatialFit</br>dwc:measurementValue</br>dwc:measurementAccuracy | These terms are expected to have literal values that are numeric. Therefore, an ```rdf:datatype``` attribute describing the form of the number should be used.
dwc:occurrenceRemarks</br>dwc:eventRemarks</br>dwc:locationRemarks</br>dwc:georeferenceRemarks</br>dwc:identificationRemarks</br>dwc:taxonRemarks</br>dwc:organismRemarks</br>dwc:relationshipRemarks</br>dwc:measurementRemarks | Because these are remarks, they are expected to have literal values with an ```xml:lang``` attribute.

dwc:basisOfRecord | Use only with literal value strings consisting of the local name component of Darwin Core class IRIs. Use ```rdf:type``` to refer to IRIs that describe the type of the resource.

[^8]: No Darwin Core terms defined by Darwin Core (as opposed to those imported from Dublin Core) have domain or range declarations as a part of their definitions. However, the five terms in the ```dwc:``` namespace listed in the table above are defined to be ```rdfs:subPropertyOf``` of ```dcterms:date```, which has the range ```rdfs:Literal```. Under the extensional entailment rule ext4 listed in section 7.3.1 of the [RDF Semantics 2004 W3C Recommendation](http://www.w3.org/TR/2004/REC-rdf-mt-20040210/#RDFSExtRules), these terms can be inferred to have the range ```rdfs:Literal```. However, the [RDF 1.1 Semantics W3C Recommendation](http://www.w3.org/TR/rdf11-mt/) does not include these extensional entailment rules. Nevertheless, it is reasonable to expect that date properties should have literal values, with datatype attributes whenever possible.
