If the connection is available why not retrieve these information

something like:

{{{
In [1]: import urllib2

In [2]: def get_epsg_wkt(epsg):
   ...:     response =
urllib2.urlopen('http://epsg.io/{epsg}.wkt'.format(epsg=epsg))
   ...:     return response.read()
   ...:

In [3]: print(get_epsg_wkt(3003))
