component reuse: identifying and building components for use in exchange analysis

GJXDM User’s Conference

September 7, 2006

Component Reuse:Identifying and Building Components

for Use in Exchange Analysis

SEARCH, The National Consortium for Justice Information and Statistics | www.search.org 2

Exchange Analysis

Work with stakeholder Subject Matter Experts (SMEs) to identify information sharing requirementsIdentify the context and content of the exchangeTriggering EventsSenders and ReceiversBusiness Rules Information

Follow a standard methodology to describe and capture exchange requirements

Accurate analysis builds the foundation for effective

component development and reuse


Building Components

Build from scratchLeveraging the work of others

The IEPD Clearinghouse contains examples of GJXDM conformant schemas that can be used as the basis of component building.www.it.ojp.gov

But…

There are no definitive standards and reconciliation may be

required between similar IEPDs

Using an Effective Methodology and Tools

Methodologies UML (Uniform Modeling Language) JIEM (Justice Information Exchange Model) Analysis BPMN (Business Process Modeling Notation)

Tools Freeware –

• ArgoUML • JIEM

Licensed –• Enterprise Architect• Visio• Exchange Modeler


UML ModelingClass / Static Structure Diagrams


Class / Static Structure Diagrams

Advantages –Can be understood by non-technical usersGraphical Component Identification is a logical

outcome

Disadvantages –Requires orientation/trainingMay not be portable outside of tool


Using JIEM to Develop Components

Freely available to analysts, users and developersAllows nesting of simple and complex elements and structuresComponents can be easily shared between exchanges and documentsIntegrates with UML modeling and IEPD development tools
