The job i'd like to use JCR for is something fairly simple. It would be
management of an e-commerce product catalog - categories, products,
SKUs, supporting media and so on. There would be a small merchandising
team editing this data. The model i have is that the repository holds
the master version of this information; when the team wants to do some
work (adding a new category of products, say), they would create a new
working copy of it, do their editing, over the course of days or weeks,
and when it was ready, fold it back into the master copy. There could
be several such bits of work in progress at once. Should i be thinking
in terms of having a workspace for the master copy, and a workspace for
each bit of work? A workspace for each bit of work with no master
workspace? A single workspace, active in multiple sessions, using
versioning to separate bits of work? Some combination of the above?
I'd tend to think of this as a single workspaces on multiple repository
instances and using an external "publish" process to move content
updates from the content development instance to the content display
instance
Okay, that's an interesting idea. In my problem, new 'bits of work' would
come into existence every day or so, and live for days or weeks. That
means i would need to create new repositories that frequently, right?
I'm interested in doing this stuff inside a web application. If i used the
'model 2' shared J2EE resource approach, with the resource adaptor version
of Jackrabbit, i think i need to define each repository in the container's
configuration. That seems like a bit of a showstopper.
If i was able to get the multiple repositories created and accessible, is
there any particular means for moving content between them? Is publishing,
or export and import, part of the JCR spec, or something Jackrabbit adds,
or would i have to implement it from scratch? I've seen references to an
export format in the spec; when you import from it, does it replace
existing content, or update it?
