even better, there is a concept of version-graph branches and merges
in the jsr-170 spec. as a graphic example you can go to 
http://jcr.day.com and choose a versionable node and click the "versions"
button.
for a quick example of a "version graph" check this out....
http://jsr170tools.day.com/crx/ui/versionbrowse.jsp?Path=/pr-jsr-170-v0.13.1/docs/api/allclasses-frame.html

merge, update, clone bring existing nodes into a 
workspace.
since workspace management & creation as 
"repository admin tasks" are not specified in 
jsr-170, it is up to the repository to eg. provide 
"tag-based"-workspaces, that dynamically
populate the workspace with nodes from a repository.
[the basic mechanics should be provided with the
above methods though...]
this is most certainly something that would be a 
welcome extension to jackrabbit.

regards,
david
