DELTA and Identification Software

DELTA: DEscription Language for TAxonomy. The DELTA format is a flexible method for encoding taxonomic descriptions for computer processing. The DELTA system is an integrated set of programs based on the DELTA format, for the generation and typesetting of natural-language descriptions and conventional taxonomic keys, conversion of data for use by classification programs (cladistic and phenetic), and interactive identification and information retrieval. By Mike Dallwitz, Toni Paine, and Eric Zurcher
DELTA-L: A discussion forum for users of the DELTA System and related taxonomic software. The DELTA-L mailing list is subscribed by users of a variety of taxonomic software. Software and data that takes advantage of any of these packages is commonly shared and debated. Subscribers are often professional taxonomists and others providing or making use of descriptive databases constructed with these packages. Managed by Eric Gouda
