[Framework-Team] five.intid

[whit]

I'm assuming not only nouri might be interested in this...

after a bit of tickling, I got a acquisition friendly version of 
zope.app.intid working and checked in. it's ready to have it's tires 
kicked::

https://svn.plone.org/svn/collective/five.intid/trunk

as part of the package, it also includes a z2 compatibility layer for 
keyreferences.

if you don't know zope.app.intid, it's super simple; basically just a 
dual btree index that uses hashable objects as keys(and these objects, 
keyreference return a target object when called).  Registration and 
unregistering are handled by object event subscribers.  Adding an object 
via the subscribers fires an IIntIdAdded event for use in 
cataloging(there is an event for removal also).

I'm planning on using this with rdflib(as a catalog). tons of other 
reference oriented code from z3 uses it(zc.extrensicreference, 
zc.relationship, lovely.tag, etc).  If you wanted a more ATish UID, 
overriding the id generation in the utility would be trivial.
