This code will download all artists in [DBpedia](http://dbpedia.org), and the schema will be same as *Data Examples*.
If there are more than one authors in a work, the authors will be appended in the same row, there will be *,* between authors.

Maybe it can be something like:

    """Loads the data of authors from dbpedia.
    
    :param LIMIT: the count of data retrieved at once.
    :type LIMIT: :class:`int`
    :param page: the number of page retrieved
    :type page: :class:`int`
    
    """

and it seems that the convention for docstrings are """ (three double quotes.)
