I try to implement a lazy-loading taxonomy tree (as a demo for a open source javascript tree plugin). See here for an example: http://rawgit.com/mar10/fancytree/master/demo/taxonomy-browser/index.html#ke... What JSON API should use to get the top level nodes (i.e. Kingdoms)? Currently I call http://api.gbif.org/v1/species/search?rank=kingdom <http://api.gbif.org/v1/species/search?rank=kingdom> but this returns much more than the ~7 entries I expect (Animalia, Plantae, Fungi, …) I seem to get reasonable results, if I only display nodes with key == nubKey. But the search results retrieved by `species/search?q=homo sapiens` returns multiple hits, and some of them have keys different from nubKey. Those matches seem to be descendants of an `Animals` kingdom that also has nubKey != key. I guess my mental model of the data structure is too naïve: - why are there different ‚Animals‘ kingdoms with different keys but identical nubKey? - does it make sense at all to display a tree (with only one ‚animals‘ node)? - when I restrict the search results to entries that have a kingdom with key == nubKey, what will the user miss?
