Maintaining reference relations between repositories

[Michael Aemisegger]

Dear list

Suppose two repositories, an author and a public repository. You can activate 
content from one to the other. The two repositories are physically separated, 
maybe located on different machines.

My use case are references to nodes (e.g. links to a page or an asset) that are 
of subtype mix:referenceable. The challenge we encounter is that the read only 
property 'jcr:uuid' is generated automatically while activating and thus 
references are lost.

How can you ensure that references in the author repository are respected in 
the public repository?

Cheers,
Michael
