Background: GJXDM and NIEM• Global has been and continues to focus on development

of NIEM in parallel to GJXDM.• Global has and continues to participate on NIEM

governance, ConOps, architecture, and outreach materials.

• Global members have heard the concerns re: future relationship between GJXDM and NIEM – such as, “what do I invest in?”

• XSTF heretofore has not managed the justice namespace, but will assume this responsibility with 4.0.

GJXDM/NIEM Governance

• GJXDM will continue in relevancy, existence. • XSTF will manage the justice namespace

• renamed in NIEM as jxdm• XSTF will have governance responsibility (within current Global

structure)

• XSTF is represented on the NIEM governing body (NIEM Business Architecture Committee, or “NBAC”) for “Common” and “Universal.”

• Governance of “Common” and “Universal” is now NBAC’s responsilbility.

GJXDM 3.1.0: Why not?

• Differences between GJXDM 3.1.0 and NIEM 1.0• Development cycle of 3.1

• Time (calendar)• Resources

• Convergence of GJXDM and NIEM is at GJXDM 4.0/NIEM 1.1 (slated for Q2 ‘07).


7

Making Decisions:3.03 and NIEM 1.0, and 4.0/1.1 • This will not effect current IEPDs ever


8

GJXDM 3.0.3 vs GJXDM 3.1 Structure• 3.0.3

• Implements only generic relationships• Roles are not supported• All metadata inherits from Supertype• Proxy schemas are used to implement code types

• 3.1

• Implements associations and roles with metadata• Implements flexible metadata containers• PropertyType and ActivityType completely

refactored• No proxy schemas are used for code lists


9

GJXDM 3.0.3 vs GJXDM 3.1 Content• 3.0.3

• Contains many deprecations accumulated from 3.0.x series

• 3.1

• Removed deprecations accumulated in 3.0.x series• Incorporates many new association and role types• Motor vehicle crash data• New security components for TWPDES and

Intelligence community• Updated NCIC tables• Many other component changes applied per

feedback through Bugzilla


10

GJXDM 3.1 vs NIEM 1.0 StructureNIEM 1.0:• Partitioned into multiple NIEM domains (including Justice)• Includes Universal, Common, and Structures namespaces (Core)• Refactors data components across all namespaces• Implements type augmentation• Implements more flexible code lists

• uses abstract code elements and substitution groups• does not use dot notation

• Implements a URI for each component• Refactors some specialization occurrences into augmentation,

associations, roles, and metadata• Uses original GJXDM 3.0.3 PropertyType and ActivityType

(GJXDM 3.1 implements substantive structural and content changes to PropertyType and ActivityType)


11

GJXDM 3.1 vs NIEM 1.0 Content

NIEM 1.0 adds (in addition to Justice):• Immigration and Customs Enforcement• Customs and Border Protection / International Trade• Intelligence• Emergency Management• Infrastructure Protection• Person Screening• External standards (Geospatial, EDXL)


12

GJXDM 3.0.3 vs NIEM 1.0 StructureNIEM 1.0:• Partitioned into multiple NIEM domains (including Justice)• Includes Universal, Common, and Structures namespaces (Core)• Refactors data components across all namespaces• Implements

• Associations• Roles• Metadata

• Implements a URI for each component• Based on GJXDM 3.0.3 PropertyType and ActivityType• Implements a URI for each component• Refactors some specialization occurrences into augmentation,

associations, roles, and metadata• Uses original GJXDM 3.0.3 PropertyType and ActivityType

• Type augmentation• Abstract code

elements


13

GJXDM 3.0.3 vs NIEM 1.0 Content

NIEM 1.0 adds (in addition to Justice):• Immigration and Customs Enforcement• Customs and Border Protection /

International Trade• Intelligence• Emergency Management• Infrastructure Protection• Person Screening• External standards (Geospatial, EDXL)


14

GJXDM 4.0/NIEM 1.1 (Q2 2007)

4.0/1.1 will converge GJXDM 3.0.3, GJXDM 3.1 features, and NIEM 1.0 into one release with built-in

migration support to subsequent NIEM releases.

GJXDM 4.0/NIEM 1.1 summary: Multi-domain, refactored PropertyType and ActivityType;

associations, roles, metadata, type augmentation, flexible code lists, URI for each component,

database export, and three integrated support tools


15

Requirements for 4.0/1.1 release:

• 3.1 functionality• NIEM Naming and Design Rules (NDR) compliance• Version independence• Lessons learned from NIEM 1.0 implementations

• Commitment from NIEM PMO to support local and state pilots


16

Question-and-Answer Period


17

Wrap-up

• GJXDM is alive and well – investments, to date, will be preserved• XSTF will continue to have governance oversight within the justice

domain• XSTF and Global are participating in the NIEM governance structure• Convergence/Interlocking will occur with simultaneous 4.0/1.1

releases• “Interlocking” means:

• NDRs and toolsets are consistent• IEPDs will be developed using both• The two data models are complementary and efficient (data is not duplicated)

and allow seamless interoperability via toolsets
