The Access to Biological Collections Data (ABCD) schema is a highly structured data exchange and access model for taxon occurrence data (specimens, observations, etc. of living organisms), i.e. primary biodiversity data.
|
|
In 2006, an 'Extension For Geosciences' was added to the schema, to form the ABCDEFG Schema, and in 2010, Biodiversity Information Standards (TDWG) published a draft standard extension for DNA, called ABCDDNA.
