The Darwin Core germplasm extension (DwC-germplasm) was developed to provide a bridge between the established standards in use by the genebank community for plant genetic resources for food and agriculture (PGRFA) and the standards maintained by the Biodiversity Information Standards/Taxonomic Databases Working Group (TDWG). The DwC-germplasm provides an extension to the Darwin Core standard of the TDWG for occurrences. Darwin Core can be seen as an extension to the Dublin Core Metadata Data Initiative (DCMI) terms.
