I haven't been looking at Java Content Repository (JSR-170/283) in
depth (will do this soon), but I guess with underlying JCR support
this feature won't be a big thing to implement.
Might be. I have a nagging feeling that the versioning support of JCR
is not what we want. The check-in/check-out process is not really
designed for this kind of an usecase.
With the existing WikiPageProvider API I was thinking of something akin
to adding a single method to support this (which is after all a pretty
common archiving feature):
/**
* Returns the most recent version number of the wiki page
* as of the Date <tt>date</tt>. If the page did not exist
* at that time, returns -1.
*/
public int getVersionAsOfDate( String page, Date date )
throws ProviderException;
This would then permit the addition of a "time machine" that would put
together a catalog of the pages based on their versions as of that Date.
I.e., the time machine would simply create an alternative set of wiki
pages as of a given date.
