dwciri [dwciri] namespace descriptor quick reference guide

Darwin Core is a standard maintained by the Darwin Core Maintenance Interest Group. The Darwin Core vocabulary including classes and their properties have been fully implemented on ther EU Pollinator Hub vocabulary. Terms in the namespace abbreviation dwciri: are intended for use with IRI reference objects and must not be used with literal objects. The Darwin Core namespace URI for the collection Darwin Core properties expected to have IRI values is http://rs.tdwg.org/dwc/iri/. For further information refer to section 2.5 of the Darwin Core RDF Guide.

Class

behavior
Definition
Behavior is a multicellular organismal process, which has been defined as follows: The internally coordinated responses (actions or inactions) of animals (individuals or groups) to internal or external stimuli, via a mechanism that involves nervous system activity.
Notes

Recommended best practice is to use a controlled vocabulary. Terms in the dwciri namespace are intended to be used in RDF with non-literal objects.

Definition
Caste may be defined as the subdivision of a colony of social insects into groups characterized by a shared morphogenetic pathway that has diverged irreversibly from that of other such groups in the colony.

Notes

Recommended best practice is describe a dwc:Event with no more than one sampling protocol. In the case of a summary dwc:Event in which a specific protocol can not be attributed to specific dwc:Occurrences, the recommended best practice is to repeat the property for each IRI that denotes a different sampling protocol that applies to the dwc:Occurrence.
