Architecture Design, Approach

• Research Development, RVAC Integration
• Platforms created from web/portal services
• Production, deployment, by mission systems not
  NVAC
• Infrastructure components need to be identified
• Based on three tier Web, Client-Server
  Architecture
• Data Services (Data management)
• Multi-layer computer Services (Process
  Management)
• User Services (User System Interface)
• Privacy security will be a service
• Reference model for SW development.

Interoperability

• What is interoperability and why do we want it?
• Interoperability is the idea that different
  developers, working almost entirely
  independently, can contribute software components
  to a common, quality-assured collection (eg, a
  repository) AND that components can easily
  obtained from this collection and easily combined
  into a larger assemblies using a variety of
  interconnection mechanisms.
• Costs/Barriers/Risks of Interoperability
• Cost, technical, psychological legal.
• Major Challenges
• Applications and enhanced analysis
• Very large, multiple diverse datasets
• Scalability
• Human-computer interfaces

Research Challenges interoperability

• Research and Barriers to Interoperability
• Large/comlex data
• Performance
• Heterogeneity
• Rate of Change
• Diverse application domains
• Fundamental change to the visualization process/
  system

Establish NVAC Architecture Panel

• Provide leadership and technical expertise for
  evolving NVAC RD architecture.
• To achieve the best, most flexible design.
• Have investment of concepts from various related
  projects
• Group knowledge on available technologies
• Increase visibility of project, becoming
  advocates for NVAC RD Architecture.
• Provide current functionality from projects.
