[Zope] Unique ID's ?

[Philippe Jadin]

Hello,

After some deep searches about the subject, I found that zope has no
real unique ID's.

For a particular application (where we can't use the object "url" as an
ID as ojects will move), I'd like to assign a unique_id property to each
object whenever they are added (the ID must be really really unique).

Is there already a patch that do that ? Is there a reason why zope
doesn't provide this facility?

Thanks in advance,

Philippe
