Taxonomy of Best-Fit to Justice Needs

• Trend Discovery Responses
• Complex multivariate analysis of multi-community
  distributed datasets ("Data Mining", "Access
  Grid")
• Command Control Systems
• Real-time collaboration/communication
• Real-time search retrieval across datasets
• Work Team Support
• Standing committees (long term)
• Task forces (short term)
• Role-based hierarchical access rights
• Transcript archival search facilities

NCSA Habanero Overview

• Initially a Real-Time Collaboration System
• Now includes asynchronous (document-based)
  interactions
• All platforms, CAVE to Palmtop
• Provides Common Collaboration Requirements to
  Support Very Many Tool Types
• Tool installation/ start/ stop/ synchronize
• Record, search replay
• Security features
• Session persistence when everyone leaves
• Floor control via central arbitrators
• Hierarchical locks keys to implement privilege
  structures

8
Command Control Foci To Date

• Habanero ISAAC projects primarily DARPA-funded
• Research directed in support of the collaboration
  needs of next-generation military command posts
  deployed forces
• NIMA/Kodak Habanero-collaborative large-format
  satellite imagery analysis project
• Kodak's LASER for the intelligence community

9
Integrated Synchronous And Asynchronous
Collaboration (DARPA's ISAAC)

• Record Replay
• Searchable Archive of Real-Time/Extended-Time
  Sessions
• Search By Date/Time, Originator, Message
  Content, Tool Used
• Random Access
• Non-Invasive Monitoring Recording
• Replay-from-Web-page
• Session Persistence

10
Command Control Foci To Date

• GeoWorlds Integrating flagship Digital Library
  Geographic Information Systems results for use in
  real-time disaster response
• Information Sciences Institute _at_ USC -- DASHER
• NCSA -- Habanero Java3D

• U. Cal. Berkeley -- Multi-Valent Documents

• UC Santa Barbara USC -- GIS

• U. Arizona NCSA -- VRML view of semantic
  clustering

11
Command Control Foci To Date

• CINCPAC/PACOM evaluating Habanero 2.0
• Mix of HP Unix, Mac, NT networks
• Military cognizance of 48 of earth's surface
• USN SPAWAR virtual environments research group
  using Habanero Portfolio (Java3D)

15
Points of ComparableTechnical Complexity

• Distributed teams needing access to data,
  numerical models, and collaboration spaces
• Enhanced access for researchers addressing
  problems in/from/of the aging population
• Collaboration and/or funding being sought from
  Census Bureau, Urban Institute, NIH National
  Institute on Aging, Social Security
  Administration, NSF, European Union, EuroStat
  U. Durham (England), World Bank, World Health
  Organization, American U., Cornell U., NCSA

16
Points of ComparableTechnical Complexity

• Alliance CPSE Portal Initiatives
• Componentized architectures(JavaBeans, CORBA,
  DCOM)
• As a general practice
• Encapsulation of collaboration primitives in
  components
• Development of multiple APIs to legacy
  systems/services
• Thin Client (next generation collaboration
  system)
• Services
