Using IBM Rational Software Architect and the CIM to Accelerate Smart Grid Application Integration

Tara Francis - AEP

Darrell Schrag – IBM

Background

AEP and IBM worked together to determine if IBM

Rational Software Architect could be used as a

single tool to manage and build CIM-based

application integration data and service definitions

and implementations based on those definitions.

This presentation will explore that process and

show its results.

Use Case Perspective

Manage CIM

The following requirements and needs were

addressed in regards to managing the CIM– The ability to compare different CIM versions to

understand release differences.

– The ability to extend the CIM and to be able to report on

those extensions (CIM extension proposals)

– The ability to preserve the integrity of the model

– The ability to mark or select elements of the CIM for

inclusion in a data definition (CIMTool)

– The ability to save those selections (CIMTool)

– The ability to restore those selections (CIMTool)

RSA and CIM

Model interoperability is still a problem today– XMI is not consistent

– Model interchange still a problem

– Diagram information lost

How is this being addressed?– Very active model interchange OMG working group

http://www.omgwiki.org/model-interchange/doku.php

– A new diagram interchange OMG working group has just

been approved and is in Finalization Task Force

(expect 1.0 spec in May 2011)

– Note: UML 2.5 submission team has agreed to include a

UML diagram interchange model




Manage CIM

Model diff and

extension reports

Manage CIM

Preserve the

integrity of the CIM

Manage CIM

Extend the CIM– Any time a new

element is added to the

model, it automatically

gets an <<Extend>>

stereotype

– Keeps track of what

you have added and

can be reported on

Manage CIM

Mark CIM elements for

inclusion in a data

definition– Items selected are given

a <<Select>> or

<<SelectAll>> stereotype

– Mirrors what you can do

with CIMTool

– Selections can be saved,

restored, or cleared

Develop Data/Service Definitions

Utilizing the selected CIM elements, transform the

model into a 2nd UML model– Selected elements plus 1 level of related elements are

moved to 2nd model• Association ends

• Attribute types

• Enumerations


Resulting model is flat

Resulting model has

XSD Data types

reference library applied


Resulting model is flat

Resulting model has

XSD Data types

reference library applied

CIM contains

representations for

standard data types

(Boolean, Integer, etc.)– Can convert this to XSD

data types

– Preference setting

determines if originals are

kept


Standard UML→XSD

transformation is flexible

to handle different XSD

styles


Standard UML→WSDL

transformation and

SoaML profile available

to utilize XSD data

definitions as part of

message data.

Develop Integration Implementation

You can go in numerous directions once you

develop a series of data definitions and/or services– Develop Java-specific integration solutions

• XSLTs

• JAXB code to process XML data

• Web Service implementations

– Utilize the data/service definitions in ESB solutions

RSA provides the following tooling to help with this: XML editor and validator

XSL schema editor and validator

Simplified XML schema graphical editing options

High performance XML schema validator

XML schema document generator

XML schema inference (XML -> XSD)

XML grammar converters (DTD -> XSD, XSD -> DTD)

XML schema to Java code generation (XSD -> Java via

JAXB – JSR222)

DTD editor and validator

XSLT editor and validator

XSLT debugger

XPath wizard

XML-to-XML mapper (also utilizes XSD and DTD as input)

XSLT implementation generator

Web Services wizards to take you through each step in

Web Service development

Generate Web Service client from WSDL/WSIL

Create Web Services from Java Beans or WSDL/WSIL

files using Axis 1.3 Web service runtime

WSDL visual editor
