empty dataset name and authors

[Remi-Gau]

Just tested it and validation passes without warning if leave an empty string ("") or just spaces (" ") for the dataset_descrtiption name .

Same for Authors.

This probably deserves a warning.

that's our old issue with generating warnings for JSON schema based validation. In that workflow we currently only have:

1. fail with an often cryptic error message because the schema is violated
2. succeed because the schema is adhered to

perhaps it'd be easier to explicitly forbid "whitespace-only" strings in the JSON schema, for example via a "pattern".

Name: #1572 will be in the next release.

Authors is supposed to be a list. There should be a warning if the list is empty or the field is missing NO_AUTHORS:

Implementation is here:

Tests are here:

We could add an EMPTY_AUTHOR issue, just like the 2+ commas issue, and warn if author.strip().length == 0.

that would be nice

FYI I just got code: 113 - NO_AUTHORS although I have authors in CITATION.cff file, as recommended.
