Comments	This term is meant to inform a user of the data whether there were non-target taxa that were detected, but left unreported. This term is only relevant if a dwc:Event used restricted search or open search methods and if a target taxonomic scope is declared. Taxonomic scope is based on the combination of eco:targetTaxonomicScope and eco:excludedTaxonomicScope. Within dwc:Events that used either a restricted search or an open search method and declared a taxonomic scope, if all dwc:Organisms that are not included within the target taxonomic scope and that were detected during a dwc:Event were reported, the value of this term should be 'true', otherwise the value of this term should be ‘false'.

Comments	This term is meant to alert users to the presence of non-target organisms (in some disciplines called “bycatch”) reported in this dwc:Event. This term is relevant only if a target organismal scope is declared. Organismal scope is based on the combination of all of the following terms: eco:targetLifeStageScope, eco:excludedLifeStageScope, eco:targetDegreeOfEstablishmentScope, eco:excludedDegreeOfEstablishmentScope, eco:targetGrowthFormScope, and eco:excludedGrowthFormScope. Examination of the organismal scope is needed in order to identify the non-target dwc:Organisms. It should be possible to confirm the expectations by investigating a dwc:Occurrences in this dwc:Event and in its child dwc:Events (if available). The value of this term should be 'true' if dwc:Occurrences of dwc:Organisms outside the organismal scope(s) as defined at the time of a dwc:Event are reported, otherwise the value of this term should be 'false'.

IRI	http://rs.tdwg.org/dwc/terms/digitalSpecimenID
Description	An identifier for a particular instance of a Digital Specimen.
Comments	A Digital Specimen as 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.

IRI	http://rs.tdwg.org/ac/terms/digitizationDate
Description	Date the first digital version was created, if different from Original Date and Time found in the Temporal Coverage Vocabulary. The date and time must comply with the World Wide Web Consortium (W3C) datetime practice, which requires that date and time representation correspond to ISO 8601:1998, but with year fields always comprising 4 digits. This makes datetime records compliant with 8601:2004. AC datetime values may also follow 8601:2004 for ranges by separating two IS0 8601 datetime fields by a solidus (`forward slash`; '/'). See also the wikipedia IS0 8601 entry for further explanation and examples.

The intended usage of this term in Darwin Core is to provide the preferred way to cite the resource itself. Note that the intended usage of dcterms:references in Darwin Core, by contrast, is to point to the definitive source representation of the resource, if one is available.
Examples	`Museum of Vertebrate Zoology, UC Berkeley. MVZ Mammal Collection (Arctos). Record ID: http://arctos.database.museum/guid/MVZ:Mamm:165861?seid=101356.

Namespace	dwcdp
Table:	EventAssertion
IRI	http://rs.tdwg.org/dwc/terms/measurementUnit
Description	Units associated with the value in assertionValueNumeric.
Comments	Recommended best practice is to use a controlled vocabulary such as the Ontology of Units of Measure http://www.wurvoc.org/vocabularies/om-1.8/ of SI units, derived units, or other non-SI units accepted for use within the SI. For units that are composed of multiple parts, use the patterns as given in "A Primer for Communicating Mathematics via Plain Text" (https://cse.sc.edu/~fenner/latex-ASCII.pdf) by Stephen Fenner (e.g., `g/cm^3` for grams per cubic centimeter). For other units, provide the value as a recognizable standard (e.g., '%') or written out in full and in the plural (e.g., `individuals`). It is fine to provide non-SI units in the original language of the dataset.
