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, ... }
folder_1
resource_A
folder_2
resource_B
I would like this function :
>>> get_by_uuid("uuid_value1")
=> return resource_A
