Humboldt Extension for Ecological Inventories

The Humboldt Extension for Ecological Inventories is a vocabulary for transmitting information about biodiversity surveys with hierarchical structure. It is used along with Darwin Core terms to extend descriptions of Events.

NOTE: This document forms part of a proposal by the Humboldt Extension Task Group to extend Darwin Core with vocabulary for ecological inventories. It is not yet ratified and may change as a result of recommendations received during the course of open public commentary. To help reviewers understand how the extension was tested and what was learned from that testing, an Implementation Experience Report is available.

The official submission for addition to Darwin Core includes the list of terms and two guides that explain how the extension must be used (isLeastSpecificTargetCategoryQuantityInclusive and hierarchical events guidelines). The Quick reference guide and Usage guide are not officially part of the addition to Darwin Core, but may provide a less technical point of entry to understanding the extension.

The Humboldt Extension for Ecological Inventories is a standard vocabulary maintained by the Darwin Core Maintenance Group. It includes a glossary of terms (in other contexts these might be called properties, elements, fields, columns, attributes, or concepts) intended to facilitate the sharing of information about ecological inventories by providing identifiers, labels, definitions, usage comments and examples.
