Dataset XSD

I am currently uploading datasets to OpenML. To allow good usage of the data I tried to add as much information as possible. However, it turns out that OpenML does not allow me to do so in the following two ways:

1. To make the process as transparent as possible, I wanted to add a description of the steps I did in the field update_comment. It turns out that it only allows for 128 characters (see here) which allows to describe this in ~1 sentence. Is there any suggestion on where to place such information, or would it be possible to make this field larger in the future?
2. I aimed to give a full description of the dataset, for example the abstract given by the authors + some additional information. It turns out that the description is limited to 1024 characters, which is for example not sufficient to upload the full description of the German Traffic sign Recognition Benchmark. Are there any plans to allow for longer dataset description strings?

Start with the linked openml.data.upload.xsd schema and trace how dataset upload metadata is validated. Compare the current limits for update_comment and description with the requested use cases, then determine whether longer values or another field is appropriate. Done means the API behavior and schema support an agreed solution, with the relevant validation covered.
