[Zope-CMF] Customizing content types

[Meilicke, Scott]

Based on my very small experience set of making two content products, I
would make separate products, perhaps using Archtypes (and Plone).  My
products, based on the News Item, upgraded just fine across CMF upgrades
(CMF 1.0 to 1.3.1).  One advantage of this is that you can inherit from a
existing content type, just adding your alterations, then reap the benefits
when the existing content type is upgraded.

Subject: [Zope-CMF] Customizing content types


I am engaged in a pilot project migrating a web site into Zope/CMF. This 
may involve customizing some of the CMF content types (adding 
properties) and/or creating new content types. I'm beyond the newbie 
stage with Zope and the CMF, but can't see far enough down the road for 
potential pitfalls. I'm concerned about upgrade problems with customized 
CMF content and, in general, the sustainability of such a project. 
Obviously it's a lot easier to simply make do with the CMF types, 
perhaps bending the meaning of Dublin Core to accommodate the metadata 
we want, but we'd prefer not to do that.

I've read the CMF Dogbowl how-to on Scriptable Type Information objects 
and the ZopeLABS article on adding custom properties to CMF default 
content. How does one determine whether to add a custom property to a 
CMF type or to create a new scriptable type altogether?

Thanks for any help, advice, thoughts.
David
