Re: [Gusdev-gusdev] deleting objects/rows

[<tw...@cs...>]

It sounds like rows that are not intended to be completely cleaned 
from the database, but the model is to keep a "version" around, is that right?  
Could you help to expand on this: What is in that version & what/who uses it?
Most of what I know about GUS versioning concepts I have gleaned from reading
Perl code in the object layer with occasional comments. 
Can you (or someone) summarize the in's and out's of GUS
versioning, or maybe point to some writeup?

many thanks 

Terry
