Motto


It was the dawn of the third age of Zope. The Five project was a dream given form. Its goal: to use Zope 3 technologies in Zope 2.7 by creating a Zope 2 product where Zope 3 and Zope 2 could work out their differences peacefully. 

(Babylon 5 season 1 intro, creatively quoted)

Motto 2


The Law of Fives states simply that: ALL THINGS HAPPEN IN FIVES, OR ARE DIVISIBLE BY OR ARE MULTIPLES OF FIVE, OR ARE SOMEHOW DIRECTLY OR INDIRECTLY RELATED TO FIVE.

THE LAW OF FIVES IS NEVER WRONG. 

(Principia Discordia)

The problem


	We're using Zope 2 in production

	Zope 2 is showing its age

	Zope 3 has better ways to do things

	But can't just switch, we have customers!

Benefits of using Zope 3 in Zope 2


	Able to use Zope 3 technologies right away

	Don't reinvent the wheel/APIs

	Better prepared for Zope 3 transition

	Evolution, not revolution

	Convergence, not divergence

%page

What works now?


	Interfaces (zope.interface)

	Schema (zope.schema)

	ZCML (zope.configuration)

	Adapters (zope.component)

	Views, including layers, skins (zope.component)

%page

Brief demo


	Show ZCML, adapters and views in action
 
%page

Next?


	Utilities (global ones should work)

	Forms

	Views (improve the current system)

	Who knows?

%page

Plans


	Relicense from BSD to generic ZPL 2.1

	Move from CVS at Infrae into SVN at codespeak.net

	Convergence; join us!
