A MetaProxyProperty is used to define the import / export characteristics for data written to or read from {{UBIK}} objects. For each [[MetaProperty]] of a [[MetaClass]], which participates in the interface, a MetaProxyProperty is related to the corresponding [[MetaProxy]]. Among a minimum configuration similar to a MetaProperty, some important additional configuration must be done on the [[Relation]] data between the MetaProxy and MetaProxyProperty ([[SYSREL_METAPROXY_PROPERTY]]).
