Transcript

  • 1. Not Quite There Yet •The SkyNet funding bill is passed. •The system goes online on August 4th, 1997. •Human decisions are removed from strategic defense. •SkyNet begins to learn at a geometric rate. •It becomes self-aware at 2:14am Eastern time, August 29th •In a panic, they try to pull the plug. •And, Skynet fights back Saturday, 29 June 13
  • 2. Who am I? • Drools co-founder • JBoss (2005) • Red Hat (2006) • Polymita Acquisition 2012 • Red Hat Platform Architect Saturday, 29 June 13
  • 3. KIE - Knowledge Is Everything KIE Drools jBPMOptaPlanner UberFire Guvnor Drools-WB jBPM-WB KIE-WB Saturday, 29 June 13
  • 4. GitHub • URL: • https://github.com/droolsjbpm/ • Bootstrap project: • https://github.com/droolsjbpm/droolsjbpm- build-bootstrap Saturday, 29 June 13
  • 5. Changes • Conventions: • droolsjbpm -> kie • knowlege -> kie • Examples • KnowledgeBase -> Kie • StatefulKnowledgeSession -> KieSession • StatelessKnowledgeSession - StatelesKieSession • Legacy API Adapter JAR • Most API’s should work with legacy adapter • KnowledegAgents have not been ported, PKG’s are not longer the unit of deployment Saturday, 29 June 13
  • 6. BRMS 6.0 Simplified Utilization Saturday, 29 June 13
  • 7. BRMS 5.0 Programmatic API KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.batch().add( newClassPathResource( "Model.drl", getClass() ), DRL ) .add( newClassPathResource( "Queries.drl", getClass() ), DRL ) .add( newClassPathResource( "General.drl", getClass() ), DRL ) .add( newClassPathResource( "Response.drl", getClass() ), DRL ) .add( newClassPathResource( "Events.drl", getClass() ), DRL ) .add( newClassPathResource( "UiView.drl", getClass() ), DRL ) .add( newClassPathResource( "Commands.drl", getClass() ), DRL ).build(); if ( kbuilder.hasErrors() ) { System.out.println( kbuilder.getErrors().toString() ); System.exit( 1 ); } KieBaseConfiguration kbaseConf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); kbaseConf.setOption( EqualityBehaviorOption.EQUALITY ); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( kbaseConf ); kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() ); Counter c = new Counter(); ksession = kbase.newStatefulKnowledgeSession(); Saturday, 29 June 13
  • 8. KieModules • Discovery • META-INF/kmodule.xml • Convention based • No programmatic api for building • Multiple Named entities • Inheritence of Resources • Defaults for lazy people • Version built in a standard Saturday, 29 June 13
