== Basics == In {{UBIK}}, a MetaClass is used to define the appearance and behavior of a certain set of future #REDIRECT [[Contentclass|content objects]] or [[Instance|Instances]]. A MetaClass can, and actually has to, inherit from another MetaClass, so it is usually also a [[Derivate|derivate]]. The inherit source can be a built in [[:Category:Metaclasses|Metaclass]], which is typically the case when customizing starts in an "empty" data model. Of course, and more likely, it will be another MetaClass that was already created during customizing. ==See also==* [[Metaclass model]]* [[Metaproperty]] [[Category:UBIK]]
