XML Building blocks for information exchange

• GJXDM started as a grass-roots effort to define
  a common XML vocabulary for criminal justice and
  public safety
• GJXDM provides fairly large objects, reflecting
  the broad scope of the effort and attempts to
  accommodate needs of everyone across the wide
  spectrum
• GJXDM includes constructs not native to
  criminal justice, such as health or intelligence
  created without a benefit of the subject matter
  expertise

NIEM Goals and Objectives

• Support and enable information sharing
  nationally, among all branches and levels of
  government
• Extends the grass roots, bottom up approach
  used by the Justice community of interest
• Synergy with the Federal Enterprise Architecture,
  especially the Data Reference Model (DRM)

GJXDM and NIEM

• NIEM aggregates knowledge from multiple domains,
  where each community of interest (COI)
  maintains its own domain and contributes to the
  common set
• NIEM, having much broader audience in mind from
  the beginning, took a different approach than the
  GJXDM to develop core objects
• Start with smallest, universally understood and
  usable
• Specialize for the particular exchanges, common
  to some or many
• Provide a space for additional specialization
  relevant to a specific area
• Separating concepts into Universal, Common and
  domain-specific keeps NIEM objects generally
  smaller, more nimble, though the number of
  objects is larger than that in GJXDM

National Information Exchange Model (NIEM)
NIEM Core (a collection of namespaces)
Core jointly governed through the NIEM
governing body

Universal namespace

participating domainsuniversally understood
very stable minimal or no subsetting
Common namespace
Requires joint governance and reconciliation but
relatively stable

Intelligence namespace

• NIEM Participants
• Bring domain content to NIEM.
• Conform to NIEM NDR.
• Agree to NIEM governance policies and procedures.
• Participate in NIEM governance.

GJXDM 3.1 Vision

• First major revision of GJXDM
• Implements associations and roles with metadata
• Implements flexible metadata containers
• Structures namespace
• PropertyType and ActivityType completely
  refactored
• No proxy schemas are used for code lists
• External enumeration updates
• NCIC break some table dependencies (e.g.,
  make/model)
• New content
• NHTSA crash data
• Intelligence

14
NIEM 1.0

• Partitioned into multiple NIEM domains (including
  Justice)
• Includes Universal, Common, and Structures
  namespaces (Core)
• Re-factors data components across all namespaces
• Implements
• Associations
• Roles
• Metadata
• Type augmentation
• Implements a URI for each component
• Re-factors some specialization occurrences into
  augmentation, associations, roles, and metadata
• Uses original GJXDM 3.0.3 PropertyType and
  ActivityType

15
NIEM 1.0

• Content (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)

16
Requirements for GJXDM 4.0/NIEM 1.1 release

• All proposed 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

17
GJXDM NIEM Convergence

• 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

18
NIEM 1.1 (2007)
NIEM 1.1 will converge GJXDM 3.0.3, GJXDM 3.1,
and NIEM 1.0 into one release with built-in
migration support to subsequent NIEM releases.
GJXDM 3.0.3

GJXDM 3.1
NIEM 1.1
JXDM 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
19
GJXDM NIEM Convergence

• Global has continued to focus on continuing the
  development of the NIEM in parallel to the GJXDM
• Global members have participated in NIEM
  governance, Conops, architecture, and outreach
  materials.
• The XSTF will govern and manage the justice
  namespace, next release will be GJXDM 4.0.
• Justice domain will be renamed in NIEM to jxdm
• Bottom Line GJXDM is alive and well
  investments, to date, will be preserved
