Development Status
PyCIM has proven to be more popular than first anticipated. However, it has not received the support and updates it requires. Should improvements such as:
- CIM 16/CGMES support,
- Difference models or
- Topological processing
be required then the original author may be available on contract. Please do not hesitate to get in contact directly.
PyCIM is a Python implementation of the IEC Common Information Model.
Current features include:
- Support for IEC 61970 15v13 and IEC 61968 11v05,
- Legacy support for IEC 61970 14v15 and IEC 61968 10v31,
- Profiles of the CIM, including: - Common Power Systems Model (CPSM) (CIM v14) - Common Distribution Power System Model (CDPSM) (CIM v14 and v15) - European Network of Transmission System Operators for Electricity (ENTSO-E) (CIM v14),
- Class and attribute documentation integrated as Python doc-strings,
- Transparent bi-directional reference handling using Python properties,
- CIM RDF/XML parsing and serialisation according to IEC 61970-552.
PyCIM has no dependencies beyond Python 2.6 or later. It can be easy_installed using setuptools:
$ easy_install PyCIM
Alternatively, download and unpack the tarball and install:
$ tar zxf PyCIM-XX.XX.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
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.
