As a result of a user suggestion at OpenSourceCMS, they have created a new "CMS feature list" section to show case the features of each CMS. This checklist of features is either comes from the developer of the CMS whom is willing to put something together (for example Nucleus CMS, zTml) or from what they could gather from the CMS official sites.
It seems to be a work in progress right now, but should help a little in the evaluation of the software.
The feature lists seem to be a readers digest version compiled from the various CMS sites, so you will have to take that with a grain of salt. For a more detailed comparison of features -- visit
