What is Delta?

The DELTA format (DEscription Language for TAxonomy) is a flexible and powerful method of recording taxonomic descriptions for computer processing. It was adopted as a standard for data exchange by Biodiversity Information Standards (TDWG).

The DELTA System is an integrated set of programs based on the DELTA format. The facilities available include the generation and typesetting of descriptions and conventional keys, conversion of DELTA data for use by classification programs, and the construction of Intkey packages for interactive identification and information retrieval. The System was developed in the CSIRO Division of Entomology during the period 1971 to 2000. It is in use worldwide for diverse kinds of organisms, including viruses, corals, crustaceans, insects, fish, fungi, plants, and wood. The programs are free for non-commercial use.
