#28: AT Content Types as default types
- Contents
Plone should move to Archetypes-based default types to make it easier to extend the built-in types - and to make it possible to leverage some of the built-in features of Archetypes.
- Proposed by
- Christian Heimes
- Proposal type
- Architecture
- State
- completed
Motivation
- CMF types are ancient, partly bad coded and lacking some import things like accessor/mutator (lot's of values are only available as attributes)
- Subclassing and enhancing CMF types is very hard
- Document doesn't support reST, pdf/doc upload etc.
- ATCT is using the full power of Archetypes and PortalTransform
- It's very easy to enhance ATCT types
Proposal
Currently Plone 2.0 is using the types from CMFDefault, CMFTopic and CMFCalendar. ATContentTypes (ATCT) is a feature improved reimplementation of the default types using Archetypes.
Implementation
ATContentTypes is a seperate product which depends on Archetypes (>1.2.5). Migration from CMF types to ATCT types is part of the product.
To make ATCT the default types and replacements of CMF types: * ship ATCT with plone and make it a requirement * run the migration of ATCT in the migration of plone * replace the CMF types with the ATCT types * disable the CMF types
Right now (2003-03-31) ATCT is mostly working and I'll publish a first testing beta when AT 1.2.5-rc5 is out.
