Event Stream

• FlexML Event Representation
• Standard lexical syntax
• Partially ordered streams rather than
  fixed-length documents
• Composed/interleaved tag sets rather than rigid
  DTD
• Supports dynamic composition of sophisticated
  processors
• Gauges as active connectors
• Gaugents as feedback controllers

• Architectural Models showhow to develop testing
  regimentfor verifying that componentsbehave as
  expected duringdynamic system evolution,integrat
  ion, and re-configuration
