> "Maybe we could add some simple sugar APIs?
> Eg something like Collection<CategoryPath> getChildren(int parentOrd)?
>  (Or maybe it returns Iterator<CategoryPath>?)"
> What about Collection<Integer> getChildren(int parentOrd)?
> Integer would be more versatile and can easily be converted to CategoryPath with TaxonomyReader.getPath.
