 Abstract
 : This guide is intended to facilitate the use of Darwin Core terms in the Resource Description Framework (RDF). It explains basic features of RDF and provides details of how to expose data in the form of RDF using Darwin Core terms and terms from other key vocabularies. It defines terms in the namespace `http://rs.tdwg.org/dwc/iri/` which are intended for use exclusively with non-literal objects.

 `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: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:otherCatalogNumbers` | There is no simple mapping because of the kinds of identifiers people use and variety of relationships that there may be among identifiers. For non-IRI identifiers expressed as string values, the string may be provided as a literal value of `dwc:otherCatalogNumbers`. Whether this is preferable to providing multiple `dwc:catalogNumber` properties may depend on community practice. `owl:sameAs` may be used to associate other IRI identifiers with the subject IRI if that is appropriate.
