Comaprison of IPTC, EoL DwC Media & Audubon Core

As part of the eMonocot and Scratchpads projects I have been doing some research to help us decide what metadata we will allow users to add to media by default. For images the International Press Telecommunications Council (IPTC) standard is generally considered de facto. While it forms a good basis for the curation of metadata of biological images and videos, in itself it is inadequate. Two schemes for extending this basis are the EoL Media DarwinCore extension and the more comprehensive Audubon Core (a proposed TDWG standard).

In order to compare and contrast these three standards to aid in our decision making I created this spreadsheet which may be of use to others.
