For starters, the capabilities are different. When a Stamp is
complete, it is no longer data-informable. Archiving will certainly
result in frozen Berts onto data-informable Orgls. That's the only
way to have parts of published documents stored (like the part used in
Now I'm totally confused. Why should archiving ever result in a
frozen Bert of all things? Orgls aren't data-informable, Stamps are.
Two examples to clarify this.
1) Machine A has a document X that quotes document Y. The quoted
material got transferred to A along with X. Machine A ought to
represent Y with a frozen Bert (because the actual document Y is
frozen) onto a partial orgl that just contains the quoted material.
Only when someone actually cares about Y itself does A bother
retrieving the rest of the contents from another machine.
"A ought to represent Y with a frozen Bert (because the acual document
Y is frozen)" Well fine. If it's actually frozen, then it should be
represented as frozen. I thought I had asked above "Why should
archiving ever result in a frozen Bert of all things?". Once again,
are you actually speaking of frozen Berts, or is this the (already
conceded) frozen Stamp issue?
2) Machine A has frozen Berts X and Y and all their data. X and Y
share data. Now the archiver throws away Y. Some other user later
gets Y from machine B which does not contain X. Now machine A has
both X and Y, but without the sharing information between them.
The last time I remember this example coming up (verbally) it was wrt
frozen Stamps. Does it have anything to do with frozen Berts?
