iDigBio is part of the U. S. National Science Foundation (NSF) Advancing Digitization of Biodiversity Collections (ADBC) project, which seeks to create a national resource of digital data documenting existing biological collections and to advance scientific knowledge by improving access to digitized information (including images) residing in vouchered scientific collections across the United States.

The iDigBio project is a joint initiative of the University of Florida and Florida State University. It is tasked with building a community to support collections digitization and deploying a data portal for information about collections and specimens.

The iDigBio data portal includes information about more than 20 million specimens and 3 million media objects. Information about these specimens and media objects are sent to the portal using a variety of transmission formats and data models. Of particular interest to this talk is the use of Darwin Core Archive files that use the Audubon Core (AC) terms.

The iDigBio team at Florida State University have developed an AC extension for the Integrated Publishing Toolkit (IPT) that is developed by the GBIF. This extension allows publishers of media information to use all of the fields of the Audubon Core. The extension was created by an automated transformation of the AC terms normative document (http://terms.tdwg.org/wiki/Audubon_Core_Term_List).

The presentation will include details of the transformation of the AC terms normative document, examples of Darwin Core archive files with AC extensions, and the presentation of AC information in the iDigBio portal.

This work is partially funded by grant from the National Science Foundation's Advancing Digitization of Biodiversity Collections Program (Cooperative Agreement EF-1115210).
