A MetaProxy is a special MetaClass used for interfacing external sources, both for import and export. The MetaProxy and its related MetaProxyProperties define the interface characteristics how the data should actually be synchronized to the corresponding UBIK® objects (instances). The synchronization uses Proxy objects to manage the data between the external sources and the internal instances.
The MetaProxies do have relations to MetaProxyProperties as well as to MetaProperties, whereas the first must be related via SYSREL METAPROXY PROPERTY by using the Relation Editor.
