1   Older versions in CPS

• NuxDocument
• NuxCPSFlexibleDocument
• NuxCPSFlexibleDocument2

Not abstract enough. Lack easy TypesTool creation. Not enough abstraction of form processing and layout. Not useable for extensible metadata.

2   Formulator

• http://www.zope.org/Members/faassen/Formulator

Not oriented toward having extensible instances. Too much oriented toward form generation. No abstraction of layout.

3   CMFTypes

• http://plone.org/documentation/CMFTypesBook
• http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/collective/CMFTypes/

Oriented toward code generation, not TTW document type creation. Types are not extensible. Presentation and validation are confused. There is no abstraction of the layout.

Has an interesting concept of text transformations but this is mixed deeply in the validation code instead of being an entirely different tool.

4   Flexible Metadata patch

• http://www.gocept.com/opensource/projects/CMF_Metadata

Only does flexible metadata.

5   Bricolage

• http://www.bricolage.cc
• http://www.masonbook.com/book/appendix-d.mhtml

Not a Zope product. Does interesting stuff.
