You can add concept definitions so that information that arrives in events or from other sources can be organized and persisted as needed, and used in rules. You can add definitions manually. You can also import database tables as concept definitions. Concept instances are created in rules.
By default, when concept instance objects are serialized to XML, properties with null values are excluded. You can change this behavior so that null values are included. You can also change the XSD for a concept object to allow null values, using the nillable attribute. See
Appendix A, Handling Null Properties for details.
If you are using the TIBCO BusinessEvents Data Modeling add-on product, you can associate a concept with a state machine. See
TIBCO BusinessEvents Data Modeling Developer’s Guide for details.
