The Global Justice Information Sharing Initiative

(“Global”)and the

Global Advisory Committee




What is Global?

• Initiative operating under the support and guidance of Bureau of Justice Assistance (BJA) and Office of Justice Programs (OJP), U.S. Department of Justice (DOJ)

• Global – through its Global Advisory Committee (GAC) – is a Federal Advisory Committee to the highest law enforcement officer in the nation: the U.S. Attorney General

• GAC Mission—improve the administration of justice and protect the nation’s public by promoting practices and technologies for the secure sharing of justice-related information

• GAC consists of broad membership (“group of groups”) – fundamental tenet of inclusiveness and collaboration

• GAC recommendations are informed by work of four Working Groups:1. Global Intelligence Working Group (GIWG)2. Global Infrastructure/Standards Working Group (GISWG)3. Global Privacy and Information Quality Working Group (GPIQWG)4. Global Security Working Group (GSWG)

Area of Emphasis:Developing and Implementing the National Criminal Intelligence Sharing Plan (NCISP)(GIWG Activity)




Area of Emphasis:Development of Recommended Fusion Center

Standards (GIWG Activity)




Area of Emphasis: Privacy (GPIQWG Activity)

1) Privacy and Information Quality Policy Development for the Justice Decision Maker (Completed)• Targets executives with a high-level, educational policy piece

underscoring the need for their attention and response to privacy and data quality issues

2) Privacy Policy Development Guide• Builds on the Policy Paper (above)• Targets those charged with actually developing the privacy policy• In-depth, hands-on manual including templates, tools, and resources• Anticipated drop date: summer 2005




Areas of Emphasis:

Information Sharing Standards and Architecture

(GISWG Activities)

• Global Justice XML Data Model (Global JXDM) and NIEM

• Service-Oriented Architecture (SOA) for the justice community – Justice Reference Architecture




Collaborative RelationshipsGlobal tenets: collaboration with other agencies and leveraging complementary activities:

• Fusion Centers• International Association of Chiefs of Police • International Association of Law Enforcement Intelligence Analysts

(IALEIA)• Law Enforcement Intelligence Unit (LEIU)• NLETS – The International Justice and Public Safety Information

Sharing Network• Regional Information Sharing Systems (RISS) Program• U.S. DOJ

• Justice Intelligence Coordinating Council• Law Enforcement Information Sharing Project (LEISP)• Law Enforcement National Data Exchange (N-DEx)

• U.S. Department of Homeland Security (National Information Exchange Model, or “NIEM”)




Global Areas of Emphasis are Important

• Promote standards-based, electronic information exchange• Consistency and widespread adoption = decrease stovepipes, increase in

capabilities• Promote information sharing that is timely, accurate, complete, and accessible in

a secure and trusted environment while vigorously considering privacy issues• Recommendations informed by input from across the entire justice spectrum –

strength in GAC composition• Emphasis on incremental strategies and support of legacy systems

• Not “all or nothing” propositions, while at the same time informing agency’s “next steps”• Emphasis on reuse (Global JXDM) and leveraging/building on existing efforts

(NIEM) and justice IT expertise = resource conservation• No need to reinvent the wheel – save time, money, and manpower• Providing real guidance and tools to the field

• Global gives a powerful voice to local, state, and tribal justice information sharing issues

Who Created the GJXDM?

of the Global Infrastructure/Standards Working Group




What is the GJXDM?

• The GJXDM, or Global Justice XML Data Model, is a large-scale, object-oriented data model with extensive inheritance, instantiated as XML Schema; composed of reusable components (~2000 data elements and ~500 data types); and designed to facilitate disparate justice entities in exchanging information quickly, accurately, and reliably




What the GJXDM REALLY is

• A data dictionary and reference model in the form of an XML Schema

• A framework that can be adapted/extended by local, state, tribal, and federal jurisdictions to support information sharing

• A work in progress• Intentionally overinclusive




What the GJXDM is NOT

• Database technology• Just XML—it is a set of objects and their definitions• Big “J” (U.S. Department of Justice) specific

• Does include courts, corrections, juvenile, etc.• A programming language• A silver bullet• A replacement for exchanges and interagency

agreements, which must still be defined• A definition of interoperability (messaging, etc.)




An AstonishinglyBrief History

• Many separate data dictionary efforts• Major data dictionary reconciliation effort• Created the Reconciled Data Dictionary (RDD)• GJXDM starts with the RDD and adds structure

• More on this in just a moment…• GJXDM 3.0.3 is the current release




Governance(Also Astonishingly Brief)• Global XML Structure Task Force (XSTF)

sets the direction of the GJXDM• Wide representation:

• Courts• State and local law enforcement• Probation and parole• Federal government• Vendor community• Academia

• Global Advisory Committee directs the XSTF• DOJ, OJP funds GJXDM development




What Do You Need to Succeed With GJXDM?

• Governance• Tools• Training• Resources • Follow best practices

• GJXDM• Software development• Domain-specific




GJXDM Design

• Standards-based• Structured data dictionary

• Represented by XML Schema• Object-oriented

• Extension • Reuse

• Enables local additions of data components




GJXDM Design (continued)

• Overinclusive and optional• Requirements, solutions, and time constraints from

rational compromises




Why Structure?

• What’s wrong with a giant Data Dictionary?• Lack of consistency

• Each person-ish object might be different

• Lack of re-use• Adding something new means adding multiple copies• Quickly becomes unmanageable




Why Structure?

• Structure buys you:• Consistency

• All people-based objects share commonalities• All document-based objects share commonalities• Etc.

• Ease of Re-use• Add new types of info in one place only• At whatever level is appropriate




Using the GJXDM

• GJXDM is a toolbox• Over-inclusive and optional

• <Citation></Citation> is a valid document• Don’t use it “as is”• Use it to create your own versions, following certain

rules• This creates a number of other schemas…




Other Schemas

• Subset Schema (or is that “Schema Subset?”)• Contains just the parts you need

• Extension Schema• GJXDM is huge, but not all-inclusive• Can add elements of your own via extension

• Document Schema• Defines root element and acts as a wrapper for your XML

documents• GJXDM itself doesn’t have a root element

• Constraint Schema• Applies other business rules, e.g. cardinality




By Hand?

• You can deal with all this by hand• You can learn about the model by reading the schema• You can create schema subsets by hand• But I wouldn’t recommend it!




Tools• GTRI Spreadsheet

• Look up types and elements• it.ojp.gov/jxdm/3.0.3/

• GTRI SSGT• Ditto, plus generate subset schemas• gjxdmtools.gtri.gatech.edu/

• Wayfarer• Inheritance and a whole lot more• www.ncsconline.org/d_tech/wayfarer/




What Do YouDo With It?

• Define exchanges• Combine schemas and documentation into collections

called IEPDs• IEPDs = Information Exchange Package

Documentation• No, I don’t like the name either

GJXDM Training

• Regional focus• Class size of 40–100• New format focused on

• Basic knowledge of GJXDM• Tools• Information exchanges




GJXDM Conformance

• DOJ Special Conditions Language• Requires conformance with the GJXDM

• DHS Special Conditions Language• Mirrors the DOJ language

• DOJ-DHS Memorandum of Understanding• Executive Order 13356, replaced by E.O. 13388

(October 25, 2005)• Establishes an Information Systems Council • Focus on information sharing and interoperable systems




Semantic Conformance

• What do we mean by conformance?• Conformance means the ability to share accurate and

reliable information using the GJXDM such that the information has the same meaning for the sender as it does for the receiver




Technical Conformance

• Import and reference GJXDM namespace or a correct subset

• If it exists, use the appropriate GJXDM component (i.e., do not create a duplicate of one that exists)

• Be semantically consistent• Use GJXDM components in accordance with their

definitions• Do not use an element to represent data other than

what its definition describes




Technical Conformance (continued)

• Apply XML Schema extension rules correctly and consistently • Naming and Design Rules (NDR)

• Exchanges conform, NOT systems• What you call data or how you use it in your own system

does not impact conformance• What counts is how you package data as XML for

exchange• There is no concept of partial conformance
