Extended Measurement Or Facts

Support for generic measurements or facts, extended version linking to occurrences. This extension (eMoF) was developed to be used in combination with the Event Core, but is also compatible with other cores.

The eMoF can store measurements or facts related to a biological occurrence, environmental measurements or facts and sampling method attributes. This extension also provides the option to provide identifiers to reference a vocabulary for the measurementType, measurementValue and measurementUnit fields.

Taxon Concept Relationship

A Darwin Core Archive extension for specifying the relationsips between taxon concepts, based on the 'TaxonRelationshipAssertion' element of the TDWG Taxon Concept Transfer (XML) Schema. Relationship types include Set Theory types (included_in, etc.) and taxonomic parent-child relationships. Taxon Concepts are specified in the DwCA 'Taxon' module, where a record must have: 1. a name (and ideally also a scientificNameID), 2. a nameAccordingTo (and ideally also a nameAccordingToID), and 3. a taxonConceptID. The latter is used as the key for subjectTaxonConceptID and objectTaxonConceptID in this module.

Die Kurzbezeichnung Zeigerwerte nach Ellenberg für die "Ökologischen Zeigerwerte von Pflanzen in Mitteleuropa" ist ein von Heinz Ellenberg Mitte der 1970er-Jahre erstmals ausführlich beschriebenes Klassifikationsverfahren für mitteleuropäische Pflanzen nach ihrem ökologischen "Verhalten" und botanischen Eigenschaften. Die Zeigerwerte nach Ellenberg sind von ökologischen und botanischen Beobachtungen und Erfahrungen abgeleitete und inzwischen größtenteils durch Standortanalysen und ökophysiologische Untersuchungen bestätigte beziehungsweise abgesicherte Kenngrößen für einzelne Pflanzenarten.
