Humboldt Extension quick reference guide

Humboldt Extension quick reference guide

This document is intended to be an easy-to-read reference to the currently recommended terms that extend the Darwin Core standard with vocabulary to describe biological inventories. This document is not part of the standard. It draws on the term names and definitions from the normative part of the standard and combines them with comments and examples that are not normative, but that are meant to help people to use the terms consistently. The category to which all of the terms in this extension correspond is the Darwin Core Event (dwc:Event) class. Comprehensive metadata for current and obsolete terms in human readable form are found in a list of terms document. CSV files with the full history of the terms, with horizontal and vertical lists of these terms and the schema for the Darwin Core Archive extension can be found in the Humboldt Extension repository.

Identifierhttp://rs.tdwg.org/eco/iri/compilationSourceTypes
DefinitionThe type of data source contributing to the compilation reported.
CommentsThis term is only relevant if the dwc:Event is a compilation in which one or more types of data sources were used. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
compilationTypes Property
Identifierhttp://rs.tdwg.org/eco/iri/compilationTypes
DefinitionA statement specifying whether data reported are derived from sampling events, ancillary data compiled from other sources, or a combination of both.

excludedLifeStageScope Property
Identifierhttp://rs.tdwg.org/eco/iri/excludedLifeStageScope
DefinitionThe age class or life stage of the dwc:Organisms explicitly excluded from sampling during the dwc:Event.
CommentsThis term is defined based on dwciri:lifeStage (http://rs.tdwg.org/dwc/terms/iri/lifeStage). Recommended best practice is to use an IRI from the same controlled vocabulary as for dwciri:lifeStage. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.

Identifierhttp://rs.tdwg.org/eco/iri/excludedTaxonomicScope
DefinitionThe taxonomic group explicitly excluded from sampling during the dwc:Event.
CommentsThe dwc:Event to which the ecoiri:excludedTaxonomicScope refers could be at any level of hierarchy. In the case of a higher level (parent) dwc:Event, include all the taxonomic groups explicitly excluded from the child dwc:Events that contributed to the parent dwc:Event. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
geospatialScopeAreaUnit Property
Identifierhttp://rs.tdwg.org/eco/iri/geospatialScopeAreaUnit
DefinitionThe units associated with eco:geospatialScopeAreaValue
CommentsRecommended best practice is to use an IRI from a controlled vocabulary of SI units, derived units, or other non-SI units accepted for use within the SI.
Examples
inventoryTypes Property
Identifierhttp://rs.tdwg.org/eco/iri/inventoryTypes
DefinitionThe type of search process used to conduct the inventory.
CommentsThis term is only relevant if the dwc:Event represents an inventory. Recommended best practice is to use an IRI from a controlled vocabulary. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
materialSampleTypes Property
Identifierhttp://rs.tdwg.org/eco/iri/materialSampleTypes
DefinitionA material sample type collected during the dwc:Event.
CommentsRecommended best practice is to use an IRI from a controlled vocabulary. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
nonTargetTaxa Property
Identifierhttp://rs.tdwg.org/eco/iri/nonTargetTaxa
DefinitionA taxon reported during the dwc:Event that is outside of the target taxonomic scope (the combination of ecoiri:targetTaxonomicScope and ecoiri:excludedTaxonomicScope).
CommentsThis term is meant to allow a taxon that is considered outside of the taxonomic scope and yet was reported in the dataset to be shared. This term is relevant only if a target taxonomic scope is declared and eco:hasNonTargetTaxa is ‘true’. Taxonomic scope is based on the combination of ecoiri:targetTaxonomicScope and ecoiri:excludedTaxonomicScope. Non-target taxa (in some disciplines called “bycatch”) can be reported at any taxonomic level. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
protocolNames Property
Identifierhttp://rs.tdwg.org/eco/iri/protocolNames
DefinitionCategorical descriptive name for the methods used during the dwc:Event.
CommentsRecommended best practice is to use an IRI from a controlled vocabulary. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
samplingEffortProtocol Property
Identifierhttp://rs.tdwg.org/eco/iri/samplingEffortProtocol
DefinitionA method or protocol used to determine the sampling effort, denoted by an IRI.
CommentsThis protocol should be associated with the values reported in eco:samplingEffortValue and eco:samplingEffortUnit. This is a specialization of eco:protocolDescription focused on effort, distinct from the survey method. The effort relates to the intensity of sampling and therefore can assist in interpreting estimates of completeness. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples
samplingEffortUnit Property
Identifierhttp://rs.tdwg.org/eco/iri/samplingEffortUnit
DefinitionThe units associated with the eco:samplingEffortValue.

Examples
samplingPerformedBy Property
Identifierhttp://rs.tdwg.org/eco/iri/samplingPerformedBy
DefinitionA person, group, or organization responsible for recording the dwc:Event.
CommentsThe sampling dwc:Event could be at any level of hierarchy. In the case of a higher level (parent) dwc:Event, include all the organizations or people involved in the child dwc:Events that contributed to the parent dwc:Event. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
Examples

targetLifeStageScope Property
Identifierhttp://rs.tdwg.org/eco/iri/targetLifeStageScope
DefinitionThe age class or life stage of the dwc:Organisms targeted for sampling during the dwc:Event.
CommentsThis term is defined based on dwciri:lifeStage (http://rs.tdwg.org/dwc/terms/iri/lifeStage). Recommended best practice is to use an IRI from the same controlled vocabulary as for dwciri:lifeStage. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.
