Subject Re: Jackrabbit temporal content
Date Thu, 26 Jun 2008 20:02:40 GMT

In the same spirit of read-only versions, you can rely on
the labeling feature of a node (this is like tagging in SCM):
- create 3 versions of the content (A, B, C)
- label the version you want to use using 
- retrieve the node with this label using 
- when you want to switch to another version reuse 

And you still can edit your content (root version) without
compromising the labeled (active) version.

If you need to update the versions, you can also use the following
labels with Node#*restoreByLabel*(...) :
- "A" for the latest version A
- "B" for the latest version B
- "C" for the latest version C
- "active" for the version to be active

There is also the branching feature with Node#clone(...) but i do not
know if a label is local to a branch or global to the node.
