== Basics ==
A Proxy object is the representant of an Ubik object (istanceinstance) for one [[Interface]].
One Proxy object can handle both, import and export of the same Ubik instance via one interface.
{{Hint|A Proxy object '''MUST HAVE''' a [[MetaProxy]] defined as its [[MetaClass]]!}}
The Proxy object has a Proxy Property for every ProxyMetaProperty defined on its MetaProxy (via the Relation "SYSREL_METAPROXY_PROPERTY").

== Value Tracking ==
* Timestamp the value was set. If it is the initial value, the timestamp is equal to the CTS of the object
The current value is stored on the origin original UBIK object.
=== Exported Value ===
* Value that was exported (and comitedcommited) via an export interface run
* Timestamp the value was exported. This is the timestamp when the export of the object was triggered
The imported value is stored on the proxy object.

== Timestamp information ==
=== CTS ===
Point of time when the Proxy instance was initially created.
=== UTS ===
Last point of time when the Proxy instance was updated.
=== Export TS ===
Last point of time when the Proxy instance was updated with export data (updated with data from the linked UBIK instance)
=== External Export TS ===
Last point of time when the data from the proxy was exported to a 3rd party system.
=== Import TS ===
Last point of time when the data of the Proxy instance was imported (forwarded the data to the linked UBIK instance)
=== External Import TS ===
