 Unfortunelaty, there are [problems](https://huggingface.co/datasets/PleIAs/YouTube-Commons/discussions/10) with loading YouTube Commons with Hugging Face Datasets.
 In order to alleviate those and to further process the dataset, I took the source parquet-files and reuploaded this fixed version to HuggingFace.
+
+## Code
+The code used for this reupload. It makes use of a git clone of the [PleIAs/YouTube-Commons](https://huggingface.co/datasets/PleIAs/YouTube-Commons) dataset.

+columns = set('''video_link

+license
+original_language
+language_id_method
+transcription_language
+source_language
+word_count
+character_count'''.split('\n'))
