ChronometricAge

Extension to Occurrence Core to capture chronometric age information to be used only in cases where the collecting event is not contemporaneous with the time when the dwc:Organism was alive in its context. Collection event information can be reported in dwc:eventDate. See also the normative term list document at https://chrono.tdwg.org/list/ and the human-friendly Quick Reference Guide at https://chrono.tdwg.org/terms/.

Darwin Core Resource Relationship

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. When used with Event Core it allows to create an additional link between the eMoF and the occurrence extension. 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.

DNA derived data

An extension to Occurrence and Event cores to capture information relating to DNA. This extension is based on the MIxS extension for Darwin Core (underway), with additions from GGBN and MIQE standards and recommendations. This definition supports the outcomes documented in Publishing DNA-derived data through biodiversity data platforms (https://doi.org/10.35035/doc-vf1a-nr22). This extension is subject to change, and recommended for early adopters who understand that data remapping may be required as things evolve.

Audubon Media Description

The Audubon Core is a set of vocabularies designed to represent metadata for biodiversity multimedia resources and collections. These vocabularies aim to represent information that will help to determine whether a particular resource or collection will be fit for some particular biodiversity science application before acquiring the media. Among others, the vocabularies address such concerns as the management of the media and collections, descriptions of their content, their taxonomic, geographic, and temporal coverage, and the appropriate ways to retrieve, attribute and reproduce them.

Germplasm accession (v20140515)

The Germplasm Vocabulary provides a set of terms (supplementing the Darwin Core terms) for describing genebank accessions. These terms are maintained by the thematic community of plant genetic resources for food and agriculture (PGRFA). Most of these terms are imported from the Multi-Crop Passport Descriptor List (MCPD) maintained by Bioversity International and the Food and Agriculture Organization of the United Nations (FAO). Some terms were also developed by the European Cooperative Programme for Plant Genetic Resources (ECPGR).

Trait measurement score (v20140515)

The germplasm vocabulary term g.germplasmID is a persistent identifier for the germplasm material (genebank accession, specimen, cultivar, etc that was the subject of the measurement experiment. NB! please report stable and resolvable persistent identifiers for g.germplasmID term when linking the trait measurement score to a germplasm occurrence described in an external Darwin Core archive. When linking to trait measurement descriptors and measurement trials described extenally to the Darwin Core archive, please include stable and resolvable persistent identifiers for g.measurementTraitID and g.measurementTrialID - resolving to information on each entity.

EOL Media Extension 1.0

This extension draws from Audubon Core, Dublin Core and others to gather information about text and multimedia. It was designed to contain all the metadata that is required to be indexed by the Encyclopedia of Life (EOL), but this extension is hopefully general enough to be useful to all text and media providers and consumers. The original extension was offline; this is a copy recovered from the Internet Archive. The issue date is estimated.
