= The concept of when to delete old data (if deemed necessary).0x000D0x000A0x000D0x000ABecause of inherent traits of the -PropertyStream- concept, data will never be deleted by default.0x000D0x000A0x000D0x000AThis might result in unacceptable storage requirements / low performance. Some functionality for deletion is therefore envisaged to be necessary to implement.0x000D0x000ASee -NoRealDeletion- for details.0x000D0x000A0x000D0x000ATODO: Not implemented as of Mar 2020. Not decided if should be in a specific -ARComponents- or just part of -ARCCore-.0x000D0x000AWill probably be a specific -BasePKAttribute- called PKRetAttribute, maybe also something added to -ClassAttribute- (or something added to -EnumAttribute-. As of Apr 2020 we have not decided where / how to tag 'entity'-classes).0x000D0x000ANote that retention at application level is also plausible. One scenario could be a high-availability log-collector delivering log-data to more simple (cheaper) final storage nodes that are not necessarily high-availablity themselves. The log-collector only has to keep data for as long as the final storage nodes are tolerated to be offline.

Edit keys at all sub levels.
