Description

Suppose I want to have an OpenML task with train/test splits that I have created myself according to some criteria, how would I go about doing that? The relevant REST-API reference page seems to suggest it is only possible to upload an XML description file, while the task splits are saved in a separate .arff file if I understand things correctly.

Start with the task POST REST API reference, then trace how the XML description and separate .arff split file are handled. Determine whether user-created train/test splits are supported and document the supported upload workflow, including the expected files and request format.
