Hi,
the JSR-170 spec explicitly states that references are within the
same workspace only. generally, there are a number of issues with
cross workspace references. to mention one, your session is
tied to one workspace and the access to another workspace
is not obvious without creating another session.
also, since there can be multiple workspaces with the node
with that given UUID it would not be trivial to identify the node
just through the UUID. referential integrity is a whole
different issue.
In JSR-283 cross repository and cross workspace references
are considered as a topic to resolve.
In my experience I found that a lot of people that were interested in
cross workspace references were not really looking for all the
attributes of a JCR reference and either ended up putting all the data
into one workspace (rightfully so, since the workspace metaphore is frequently
abused as some grouping or even access control mechanism) or
used for example UUID's as strings and resolved the reference in the application
with a getByUUID() call on the target workspace.
Maybe you can outline your usecase a little bit more in detail, I
would be happy to see what suggestions I could come up with.
regards,
david
.ps: I read the property in your example as a "reference" property,
since there is no
"referenceable" property. I assume that's correct, right?

Please forgive me, but my question is not Jackrabbit specific.
What I want to do is be able to refer from one node via a property to
another node in a different workspace. For example:
WorkspaceA
root node
Node 001
Property:REFERENCEABLE, value=??? can I refer to Node 00X, UUID
00000123??
WorkspaceB
root node
Node 00X
UUID = 00000123
Is this possible in Jackrabbit? Is this possible in other implementations
of the JSR-170? Is this something that is not defined by the JSR-170? I
have read thru the Spec, and it does not seem to address this, so I am
assuming that the JSR-170 does not address this. It talks about
corresponding nodes (which I am not sure I understand yet), but this does
not seem to address the question I am interested in.
Thanks.
