This reminds me of the problem with naming knots. The Ashley Book of Knots (ABoK) has been the standard for quite some time, but it is still a difficult problem to index and search. As with this article, many knots, like many folds, have been "discovered" multiple times over the centuries, and naming & giving credit is clearly a challenge. I'm glad to see this article, but I don't see a solution any time soon. As the author explains, different countries claim credit, how would one go about proving provenance? I find it a fascinating problem.
