cobalt 5.0.0

A lightweight library for working with Akoma Ntoso Act documents

Cobalt is a lightweight Python library for working with Akoma Ntoso documents. It makes it easy to work with Akoma Ntoso documents, metadata and FRBR URIs.

It is lightweight because most operations are done on the XML document directly without intermediate objects. You still need to understand how Akoma Ntoso works.

Quickstart

Install using:

$ pip install cobalt

Use it like this:

>>> from cobalt import Act
>>> act = Act()
>>> act.title = "Act 10 of 1980"
>>> act.frbr_uri = "/za/act/1980-05-03/10"
>>> act.frbr_uri.year
'1980'
>>> act.frbr_uri.date
'1980-05-03'
>>> act.frbr_uri.number
'10'
>>> act.frbr_uri.doctype
'act'
>>> print act.to_xml()
[ lots of xml ]
