I've already looked zope.catalog and repoze.catalog.

Question : I haven't docid, can I use uuid here ? but it isn't the 
feature I want : I would like retrieve my object from uuid.

Do you have an example of code about it ?

More information about my aim :

root (ZODB)
   uuid => { "uuid_value1": resource_A, "uuid_value2": resource_B, ... }

I would like this function :

 >>> get_by_uuid("uuid_value1")
=> return resource_A
