The Brewer JSON Python Module provides the functions to connect to the RBCC-E database and to download data of the different Brewer equipments.

We describe here the functions implemented in brewerjson.py module. The last version of the python module is available from rbcce subversion repository.

Brewer JSON library can be imported from python code adding the path to brewer.py module to the Python path (list of directories Python goes through to search for modules and files):

import sys
sys.path.append("/home/to/module/")

Alternatively, you can download brewer.py file to the standard location for third-party Python modules. This location varies by platform and by how you built/installed Python itself. Typical locations are shown in the following table:

This function retrieve brewer data using the interface describing in the access functions Section. This function accepts only an argument params which is a dictionary.

  data=brewerjson.check_hg(params)

In this example we retrieve data from the url: http://rbcce.aemet.es/eubrewnet/getdata/getDS?brewerid=037&date=2014-10-01
