The persistence client library (PCL) has a backend to store key/value data and resource configuration table data (RCT) for the key/value. The persistence administration service (PAS) creates the key/value data and the configuration data during software loading process.
As both components need to implement this backend to access the key/value and configuration data, the code has been moved into a separate library which can be used by both. The library is called persistence common object. It is only possible to use one specific backend in a system for the PCL and the PAS. In order to extend the PCL with custom backends for a specific key/value resource, the plugin API must be used.
