- DELTA (DEscription Language for TAxonomy)
The DELTA format (DEscription Language for TAxonomy)
is a flexible method for encoding taxonomic descriptions for computer processing. It has been adopted by the International Taxonomic Databases Working Group (TDWG) as a standard for data exchange. DELTA-format data can be used to produce natural-language descriptions, conventional or interactive keys, cladistic or phenetic classifications, and information-retrieval systems. - Den virtuella floranSwedish Natural History Museum; in Swedish.
