[Zope-CMF] Re: cmf 1.4 planning - CMFTypes

[Yuppie]

Hi!


I had a closer look at CMFTypes. And now I've got a lot of questions 
about integrating it into CMF:


Basic features: (hope this classification makes sense)

I hate redundant code. So I like the idea. But this framework doesn't 
just help creating classes. It seems to have a full template generator 
and form validator. (The validator depends on plone? formulator?)

Is it the Right Thing to generate templates from templates? How would 
you customize the skin? Changing CMFTypes templates or the generated 
PageTemplates?

Is it the Right Thing that CMFTypes has its own form validation machinery?


Extra features:

Should the CMF implement a Unique Content ID? Does this reflect the 
discussion about Unique Object Ids?
http://www.zope.org//Wikis/DevSite/Proposals/ExplicitObjectReferences

There was a lot of discussion about extending metadata. Is this a better 
solution than the 'flexible metadata patch' or other approaches?

content_driver depends on win32 extensions
<http://starship.python.net/crew/mhammond/win32/Downloads.html>
or wvWare installer
<http://download.sourceforge.net/wvware/> .
Is this a Good Thing?

Are there other important features I don't know about?


General Questions:

I don't know zope3. Are the concepts of CMFTypes future compatible?

Did someone talk to the authors of CMFTypes? Do they want to help 
getting this into CMF 1.4? At least they have to give permission to 
relicense the contributed code under ZPL, right?

TIA,
Yuppie
