org.dmlite.model.IEntity

An entity is a concept with properties and neighbors. It has two predefined properties: oid (object artificial identifier) and code. An entity may be related to other concepts that are called neighbors. A neighbor is either of the IEntity (max. cardinality of 1: parent) or IEntities (max. cardinality of N: child) type. The entity semantical id (identifier) consists of one or more properties and/or one or more parent neighbors.

The entity concept is configured in the specific-model-config.xml file.
