I have a sqlite based "node storage class":
@shadow maglink.py
maglink declarations
class MagLink
class Node
class Backend
esc
getChildMetadata
getChildren
getConCursor
getMasterNode
getNewID
getNode
getNodeCount
getNodeMetadata
moveNode
detachNode
setChildren
setNode
setNodeMetadata
from my ill-advised, and yet successful :-) attempt to replace Zope :-) It's a
SQLite/CherryPy/Genshi stack. I use it to generated this site:
http://DulcimersInDuluth.com/ - it works completely TTW (Through The Web). I
don't like it because it does the same thing Zope/Plone does, puts all your
stuff in one large binary file you can't access unless the system is running.
I had trouble getting it ported from lxml 1.x to 2.x, or something like that,
issues with xi:include processing. But all that's irrelevant to the node
storage class above.
I'm not sure how great the code is, it's several years old now.
