  10. Areas of Emphasis:Information SharingStandards and Architecture(GISWG Activities) • Global Justice XML Data Model (Global JXDM) and NIEM • Service-Oriented Architecture (SOA) for the justice community – Justice Reference Architecture

  11. Collaborative Relationships Global 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”)

  12. 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

  15. Who Created the GJXDM? Global XML Structure Task Force of the Global Infrastructure/Standards Working Group

  16. 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

  17. 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

  18. 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.)

  19. 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

  20. 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

  21. What Do You Need to Succeed With GJXDM? • Governance • Tools • Training • Resources • Follow best practices • GJXDM • Software development • Domain-specific

  22. GJXDM Design • Standards-based • Structured data dictionary • Represented by XML Schema • Object-oriented • Extension • Reuse • Enables local additions of data components

  23. GJXDM Design (continued) • Overinclusive and optional • Requirements, solutions, and time constraints from rational compromises

  24. 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

  25. 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

  26. 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…

  27. 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

  28. 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!

  29. 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/

  30. 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

  31. IEPD Development Life Cycle

  32. Look Before You Create • Someone may have already done it • Someone may be working on it • Someone may be thinking about it • IEPD Clearinghouse, http://it.ojp.gov/iepd/ • Be sure to register your project

  33. Technical Assistance Sources • GJXDM Training and Technical Assistance Committee • GJXDM Executive Briefing • GJXDM Developer Training • GJXDM Help Desk and Listserv • Technical Assistance • IACP • IJIS Institute • NCSC • NGA • NLECTC • SEARCH

  34. Resources for Understanding the Model • GJXDM Help Desk • it.ojp.gov/gjxdm/helpdesk/ • GJXDM Listserv • www.it.ojp.gov/topic.jsp?topic_id=97 • GJXDM User Guide • it.ojp.gov/documents/GJXDMUserGuide.pdf • GJXDM Technical Overview • www.ncsconline.org/D_Tech/gjxdm/ctc9/articles/carlson.pdf

  35. GJXDM Training • Regional focus • Class size of 40–100 • New format focused on • Basic knowledge of GJXDM • Tools • Information exchanges

  36. 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

  37. 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

  38. 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

  39. 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
