Short summary
Natural history museums harbor millions of collection items. To exchange and publish the associated data, an appropriate standard is essential. ABCD (Access to Biological Collection Data) enables together with its extension EFG (Extension for Geoscience) sharing and publishing of data related to biology, paleontological, mineralogical, and petrological objects. Here, we review the history of ABCDEFG and highlight its usage by different initiatives and for the data publication in various portals.
