Thank you.

Ah, you mean things like visibility and private/public access to things, 
right?

Heh! so then this is in a lot of ways a re-hash of your work. :D
If you'd like to share tips/, info, or even stories about it I'd love to 
hear.

Much the same that I was thinking.

Ah, I see. The export/edit/import is certainly a way to handle that -- I 
was leaning towards a sort of buffer/workspace methodology, keeping the 
inconsistent things separated out of the [main/shared] system.

One of the references "Workspaces and Experimental Databases: Automated 
Support for Software Maintenance and Evolution" (URI: 
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.26.2533&rep=rep1&type=pdf 
) shows an interesting way to use a hierarchical structuring of 
databases to handle consistency/correctness for a project.
