class EsdcDataStore(DataStore):
    """
    A Cate data store implementation exposing each configured ESDC as an individual data source.

    ESDC are configured in Cate's configuration file ``$HOME/.cate/<version>/conf.py`` as follows:::

         esdc_data_sources = [
             (id, title, data_cube_dir_path),
             ...
         ]

    The ``esdc_data_sources``entries are 3-element tuples as follows:
    * *id* is a string that should by prefixed by "esdc.";
    * *title* should be a non-empty, human-readable text;
    * *data_cube_dir_path* is a string pointing to aESDC directory in your local file system.
