Ontology Functions Ontology functions are generated by TIBCO BusinessEvents based on the concepts, events, and rules in your project. There are three types of ontology functions: • Constructors — Allow you to create a simple event or concept instance. • Time events — Allow you to create and schedule a time event. See Chapter 10, Time Events and Scheduler Functions. • Rule functions — Allow you to invoke a rule function. See Chapter 16, Rules and Rule Functions. The Ontology Functions area uses the same folder structure as the project (or rather, a subset of that structure). Various ontology functions appear depending on the project and the add-on products installed: • The ontology functions catalog lists all the entity types in a project. Each type has a function for creating an instance of that type. • Each rule function also has an ontology function enabling it to be invoked in rules. • When TIBCO BusinessEvents Views is used additional ontology functions are available for each entity type. See TIBCO BusinessEvents Views documentatoin for details.
