UCore: Multi-agency lightweight information exchange schema

• Support message routing, retrievel, and analysis
• Meant for tagging/wrapping messages, a "digest"
• Who/What/When/Where
• Terms in natural language definitions
  • Mismatches between taxonomy relationships, ambiguities
• 55 terms in UCore taxonomy

UCore SL: Additional OWL based ontology constructed from UCore schema elements

• Work behind the scenes to provide additional semantics for applications working with UCore
• "Treat the XML-labels in UCore 2.0 messages as annotations for particulars (for instance individual agents) about which these messages contain information

"Every UCore SL term is defined in terms of necessary and sufficient conditions following the Aristotelian schame, which defines each child term 'A' in terms of its immediate parent 'B' together with the differentia 'C' which determines what it is about the B's that makes them A's"

• In natural language mostly

C2Core takes UCore SL and extends terminology for C2
