What is Cimphony?

• Result of over 6 years of development to research
  and support the use of CIM
• Funding from the UK Government (Energy Physical
  Science Research Council), National Grid UK and
  EDF RD (France)
• An underlying framework for loading and
  interpreting CIM data in-memory
• Various tools built on top of this framework for
  using CIM data

Architecture Overview

• Written in Java runs on Tomcat as a Web
  Application for local or remote access
• Initially supported only a single Information
  Model
• Tools developed with a web interface (Firefox)
• Web Services support was added using SOAP

4
Interop Support

• Used at the 2008 Interop for Instance Model
  Validation of CIM RDF XML files
• Cimphony includes an interface for defining
  Validation Rules in a logical manner
• Stored as an XML file and compiled at runtime
• CPSM was defined in this way
• Instance models were then validated against these
  rules

Toolset

• Cimphony includes tools for
• Importing CIM data in RDF XML
• Viewing and Editing this data
• Exporting in RDF XML
• Defining Validation rules
• Performing Validation of models

6
Toolset

• Creating Difference Models by comparing two
  models
• Applying difference models to existing models
• Defining conversion rules between Information
  Models
• Applying conversion rules to model instances
• Creating Google Maps and Google Earth views of
  models with embedded Geographical Data

Beyond CIM

• Initially the software was written with support
  for a single Information Model (CIM)
• Created from the CIM 11 release and then manually
  updated each year
• Was proving unmanageable and new software
  required support for multiple CIM versions and
  CIMExtensions

8
Beyond CIM

• Architecture was re-worked so that multiple
  Information Models could be supported
  simultaneously
• A tool was written to take an XMI and build
  Cimphony Java classes and supporting meta-data
  from it
• Majority of tools were already Information Model
  agnostic

9
Availability

• Until now the software has been for download to
  available only to University research partners
  and Interop participants
• As of 2009 the software will be released as Open
  Source
• A combination of GPL and LGPL licensing
• Anybody can download and run the software

Performance

• Since December significant work has been put into
  increasing performance and reducing the memory
  footprint of the latest builds of Cimphony
• ERCOT 11,000 bus test network (250Mb XML used at
  Interop) imports in 3 minute 10 seconds and
  validates against the CPSM in 1-2 seconds
• UCTE test network imports in 1 minute 20 seconds
• Has support for reading and writing to ZIP files
  natively with no noticeable performance penalty,
  so UCTE network becomes a 5Mb file instead of
  150Mb
