The Business Context
Many independent agencies and funding bodies
Many levels and branches of government
Widely different scales of operation Wide variety of legacy hardware and
software Constantly changing requirements
Global Justice Information Sharing Initiative Advisory Committee(Global)
22 of 31 groups state or local.
4 Working Groups Standards Security Privacy Intelligence)
The Challenge: Information Sharing Across Agencies and Disciplines
The Vision:
“Any member of the Justice Community can access the information they need to do
their job, at the time they need it, in a form that is useful, regardless of the location of
the data.”
A Framework for Justice Information Sharing: Service-Oriented Architecture (SOPA), The Global Infrastructure/Standards Working Group,
Dec. 9, 2004
Solution: Service Oriented Architecture (SOA)
Uses the open standards of the Internet.
Builds services one business process at a time.
Technology now reflects reality of government information sharing.
Dramatic management and policy implications.
SOA Attributes:1. Focus is on linking
system to system.2. Uses STANDARDS for
making the links.3. Exploits Internet-
based middleware.4. Independent of
hardware.
(Barry’s Audio System
Analogy)
Web Services Version of SOA Assumptions
Open Internet Protocols Define content (GJXDM) Define services
Content Delivery mechanism Business rules (security, privacy, ID’s)
Data comes from the Sources Think of Internet searches
SOA Development
Requirements: Open Standards
Content: data (GJXDM) Delivery: messaging profiles
Common Business Rules Registries
Requirements Standards (official versions) Instances (examples)
Meeting the Requirements
Standards Setting Bodies Public: GJXDM/Global, NIEM Private: W3C, OASIS, WS-I
Modeling and Testing Wisconsin, NLETS, ARGIS, JNET,
Colorado, NCSC, CAP, ICE
Who’s Doing What?
Security WG (security & ID) Privacy WG (privacy, public access) Standards WG (services, registries,
business rules, governance)
XSTF & NIEM (GJXDM) GTTAC (message profiles)
Management & Policy Implications
Incremental Development System is an accumulation of individual
services. Management Involvement
Services are developed around business processes.
Legacy Systems Legacy systems are leveraged.
Management & Policy (Con’t)
Investment Strategies On-going investment Fallacy of building analogy
Data Ownership Data stays at home Virtual warehouses
SOA itself a Work-in-Progress Begin skill development
Major Business Implications
Reuse of services (messages) and micro-services (data components) to eliminate redundant development
Governance of services and data components by multiple groups by appropriateness
