Description

I am having some problems with the ARFF files from the website.

From the LIAC-ARFF you get ARFF strings that have the RELATION, DESCRIPTION, ATTRIBUTES and DATA in capitals, at least in the version that I am using 'liac-arff 2.2.2'.

However from the website you get ARFF files that have those attributes in lower case,
This would be okay in a sense but when I check the latest datasets that I have uploaded, they have the attributes in upper case.
Is this intended ?

Upper case
https://test.openml.org/d/2138
Lower case
https://test.openml.org/d/99

Research direction

Start by comparing the ARFF output for datasets 2138 and 99 on the linked test website with the output from liac-arff 2.2.2. Trace the website path that generates or serves these files, then determine the intended attribute casing. Done means the casing is consistent with that decision and the discrepancy is covered by a check or documented behavior.
