RCS

The main rcs.py module.

The starter module for RCS. Currently it contains most of the functional code for RCS and this should eventually end up in separate modules or packages.

class rcs.Doc

Container class for all web requests for single documents

__module__ = 'rcs'

get(*args, **kwargs)

A REST endpoint for fetching a single document from the doc store.

Parameters:

• lang – A two letter language code for the response
• smallkey (str) – A short key which uniquely identifies the dataset

Returns:

Response – a JSON response object; None with a 404 code if the key was not matched

methods = ['GET']

class rcs.DocV09

__init__()

__module__ = 'rcs'

endpoint = 'docv09'

mediatypes(resource_cls)

methods = ['GET']

class rcs.DocV1

__init__()
