PyCIM 14.15.1

Installation

PyCIM has no dependencies beyond Python 2.5 or later. It can be easy_installed using setuptools:

$ easy_install PyCIM

Alternatively, download and unpack the tarball and install:

$ tar zxf PyCIM-14.15.tar.gz
$ python setup.py install

On UNIX systems, use sudo for the latter command if you need to install the scripts to a directory that requires root privileges:

$ sudo python setup.py install

The development Git repository can be cloned from GitHub:

$ git clone https://github.com/rwl/PyCIM.git

Using PyCIM

To use PyCIM with the Python interpreter, iPython is recommended. For example, to instantiate a ConnecticityNode:

In [1]: from CIM14.IEC61970.Core import ConnectivityNode

In [2]: node = ConnectivityNode(name='Node 1')

To associate the node with a Terminal:

In [3]: from CIM14.IEC61970.Core import Terminal

In [4]: t = Terminal(name='T1', ConnectivityNode=node)

In [5]: node.Terminals[0].name
Out[5]: 'T1'

To add a Terminal to a ConnectivityNode:

In [6]: t2 = Terminal()

In [7]: node.addTerminals(t2)

In [8]: t2.ConnectivityNode.name
Out[8]: 'Node 1'

To view the docstring for an attribute:

In [9]: t.connected?
Type:     bool
Base Class: <type 'bool'>
String Form:    False
Namespace:  Interactive
Docstring:
    bool(x) -> bool

    Returns True when the argument x is true, False otherwise.
    The builtins True and False are the only two instances of the class bool.
    The class bool is a subclass of the class int, and cannot be subclassed.

To parse a CIM RDF/XML file:

In[1]: import logging

In[2]: logging.basicConfig(level=logging.INFO)

In[3]: from PyCIM import cimread

In[4]: d = cimread('path/to/input_file.xml')
INFO:PyCIM.RDFXMLReader:Created 5660 CIM objects in 1.04s.

The cimread function returns a Python dictionary that maps UUIDs to CIM objects. To serialise the dictionary of objects:

In[5]: from PyCIM import cimwrite

In[6]: cimwrite(d, 'path/to/output_file.xml')
INFO:PyCIM.RDFXMLWriter:5660 CIM objects serialised in 1.14s.
