          The Eclipse organizations format is a JSON document stored under the
          "organizations" key. The next JSON shows the structure of the
          document:
  
          {
            'organizations' : {
                 '1': {
                     'active': '2001-01-01 18:00:00',
                     'id': '1',
                     'image' : 'http://example.com/image/1',
