class DataFilesList(List[str]):
    """
    List of data files (absolute local paths or URLs).
    It has two construction methods given the user's data files patterns:
    - ``from_hf_repo``: resolve patterns inside a dataset repository
    - ``from_local_or_remote``: resolve patterns from a local path

    Moreover, DataFilesList has an additional attribute ``origin_metadata``.
    It can store:
    - the last modified time of local files
    - ETag of remote files
    - commit sha of a dataset repository

    Thanks to this additional attribute, it is possible to hash the list
    and get a different hash if and only if at least one file changed.
    This is useful for caching Dataset objects that are obtained from a list of data files.
