In {{UBIK}}, a MetaProperty Metaproperty describes a single feature of a certain [[MetaClassMetaclass]]. A MetaProperty Metaproperty will never hold own values, but it serves as a definition for a resulting [[BaseProperty]] on a derived [[Instance|ContentClass]].
For enhanced reuse, MetaProperties can be organized in a Pool and linked to many MetaClasses, using the [[SYSREL_METAPROPERTY|Systemrelation MetaProperty]]
