def _create_atom_id(resource_path, authority_name=None, date_string=None):
"""
Helper method that creates an atom id for a feed or entry.
An id must be unique, and must not change over time. ie - once published,
it represents an atom feed or entry uniquely, and forever. See [4]:
When an Atom Document is relocated, migrated, syndicated,
republished, exported, or imported, the content of its atom:id
element MUST NOT change. Put another way, an atom:id element
pertains to all instantiations of a particular Atom entry or feed;
revisions retain the same content in their atom:id elements. It is
suggested that the atom:id element be stored along with the
associated resource.
resource_path
The resource path that uniquely identifies the feed or element. This
mustn't be something that changes over time for a given entry or feed.
And does not necessarily need to be resolvable.
e.g. ``"/group/933f3857-79fd-4beb-a835-c0349e31ce76"`` could represent
the feed of datasets belonging to the identified group.
authority_name
The domain name or email address of the publisher of the feed. See [3]
for more details. If ``None`` then the domain name is taken from the
config file. First trying ``ckan.feeds.authority_name``, and failing
that, it uses ``ckan.site_url``. Again, this should not change over
time.
date_string
A string representing a date on which the authority_name is owned by
the publisher of the feed.
e.g. ``"2012-03-22"``
Again, this should not change over time.
If date_string is None, then an attempt is made to read the config
option ``ckan.feeds.date``. If that's not available,
then the date_string is not used in the generation of the atom id.
Following the methods outlined in [1], [2] and [3], this function produces
tagURIs like:
``"tag:thedatahub.org,2012:/group/933f3857-79fd-4beb-a835-c0349e31ce76"``.
If not enough information is provide to produce a valid tagURI, then only
the resource_path is used, e.g.: ::
"http://thedatahub.org/group/933f3857-79fd-4beb-a835-c0349e31ce76"
or
"/group/933f3857-79fd-4beb-a835-c0349e31ce76"
The latter of which is only used if no site_url is available. And it
should be noted will result in an invalid feed.
