Having apparently successfully used https://www.myfossil.org/audubon-core-wizard/ do I expect that the wizard generates the Audubon Core (AC)? If so, how do I fetch it? If on the other hand I am expected to provide the AC, how do I do so and how is it subsequently fetched?
As @kcrippen noted, Max Jones (@mjones) and Eric Poirier (@epoirier) are the external web developers and they should be able to give you some more information about the AC wizard design. To my knowledge, AC data capabilities exist but are not currently being utilized — that will be implemented in the future with a redesign of the Fossil Gallery. However, @mjones did a lot of research and should be able to tell you more of the nitty-gritty details about crafting the wizard.
