A
Date Based Redirect (DBR), is a special Meta Data Redirect
?, which is evaluated according to the current time and date. A DBR with a frequency of a day will point at a new target key every 24 hours. If this new target is always inserted before the DBR rolls over, the illusion of having the "same" document that is still updatable is achieved. If nothing resides at the current target, it appears as if the content were "deleted". Freenet will offer to use the Redirect to the past Version in case of a DNF Error.
It should be noted, though, that by not going through the DBR one can access the target corresponding to any time in the past (as long as the content has not been "pushed out" to make room) or future (as long as the content has been already inserted).
The problem is it is not clear how useful they are for documents that change at irregular intervals. DBR sites, also, may not be retired, as they will brake soon, after future-dates insertions expire. At this time, DBR Sites are mainly used for frequently updated content like Dolphin's Freesite Index at "SSK@sPolFAwS69lG2Le%7eTTRzNEVarcEPAgM/DFI//"
As of today, probably the best way for most cases is the use of "edition" publishing.
