Hi,
just how we are using BTrees and traversal. I hope it may help or give
inspirations.
We developed zodict[1][2] and are using it with great success in pyramid
applications together with node.ext.zodb[4][5] (which is based on
zodict) as the foundation for traversal based applications.
For a ZODB Storage for (lots of) searchable (light weight) data we
developed souper[5][6], but it does not target on traversal (so maybe OT
here, just to to paint the whole picture).

Hi
i'm building a web application based on pyramid and traversal in a ZODB.
So far it's working fine with Container derived from Persitent Mapping.
But some containers will get many children so i'm trying to use a BTree
based Container. So far no success.
I've tried
from BTrees.OOBTree import BTree
from persistent import Persistent
class container(BTree, Persistent)
I'ts working but changes don't geht stored in the zodb.
I there a example how to do this out there or can someone get mit a Hint
what im missing.
Regards
