Unified Content Model Working Group

From Joomla! Documentation

The Unified Content Model Working Group is a Production Working Group. UCM is powerful new tool that is proposed for inclusion in the Platform. What use will the CMS make of it, what are the backward compatibility issues involved, what new coding would be needed to use it in the CMS, and what are the implications for third party extensions are all open questions.

Technical Work produced by this group



This effort can be thought of as two coordinated efforts:

  • Work on the CMS 3 series to implement UCM for the core and extensions that wish to opt into it.
  • Work on a the CMS 4 series that would be built around this model as well as other architectural changes.


  • Initial infrastructure for use of a single core table: 3.1.
  • Migration to a the single core content table for all or most core components for 3.2
