		This version of UCore is adopted from the DoD/Energy/Justice/Homeland Security information sharing initiative, UCore,to create a small common core of terms for National Information Exchange Model [NIEM] messaging within and across multiple agencies(http://semanticommunity.info/@api/deki/pages/3953/pdf).  For the purpose of the F6 DARPA program, we have merged useful classes from UCore-SL and UCore 2.0.
