Nadia, helper script for it.ckan.net
````````````````````````````````````

Nadia is an helper script to populate it.ckan.net.  We have a large
data set regarding public section information in Piedmont and in
Italy.  And this data set is composed of a collection of XLS files.
Each file is organized in a tabular way, but the script we use to
upload to CKAN expects a linearized data set.  This is the task of
nadia.

To linearize an XLS file you need to prepare a configuration file
that describes the structure of the XLS file.  Then, assuming the
configuration file is named FOO, you can invoke `./nadia.py FOO'
to linearize the XLS file.  Assuming the original file was named
BAR.xls, nadia will create a linearized CSV output file, which will
be named BAR.xls.nadia.csv.

Nadia depends on Python >= 2.5 and on json.  If Python >= 2.6 json
is already part of the standard library, otherwise you need to install
simplejson.  There are other dependencies, but they are shipped together
with the nadia distribution and so you don't need to install any
additional package.

Please read doc/HOWTO (or doc/HOWTO.html) to learn how to prepare a
configuration file.
