Retrieves a component from Globus Search.

The returned value is in the following form:

.. code-block::

{
    "data": {
        "published": <published_document>,
        "draft": <draft_document>
    }
}

where at least one of the "published" or "draft" entries must be present. If the Globus Search subject has an entry with name "Published", its document will be placed under <published_document>. If the Globus Search entry has other entries, the document for the last such entry will be placed under <draft_document>. This method does not ensure that only one draft-type entry is present.

If no entries exist under the given Globus Search subject or if Globus Search returns a 404 error, this method will raise a 404 error. If Globus Search returns an error other than a 404, a 500 error will be raised.

If a bearer token is included, the response will contain items which are visible to the identity associated with the token. If no bearer token is included the response will only contain items which are publicly visible.

:param id: The ID (Globus Search subject) of the data release to retrieve. :optional_param token: A valid bearer token for the user. :return: A JSON document as described above.
