So why not just a Content Management Framework ( CMF ) where you can create them all? The more I think of it, I can say that it's like a phpMyAdmin for content
I think this is the typical workflow of a CMF from a users point:
- Create a Content Type (i.e. blog)
- Create a Field Group and associate it for that Content Type
- Add custom fields into that Field Group.
- (Optional) Create and associate a Categories Group for that Content Type.
- (Optional) Add categories to that "Categories Group".
- Create a "View" for that Content type - this will what users see in your site.
- (Optional) Create a "Form" for that Content Type if you want your users to submit content.
- Same step can be done if you want to create another Content Type, i.e. an article system.
- ExpressionEngine (EE) - by far this is my personal favorite. The hard thing about EE is creating the "View" part if you're a beginner. You have to study its own template tags and documentation before you can create a "View". The good thing about this is you have full control of your "View" - you can load a bunch of useless CSS and HTML tags or you can write SEO-friendly, semantic code.
- ProcessWire - it has similarities to EE and creating the "View" part is also a little bit hard - it uses PHP as templating system.
- IPB IP.Content - I think most here already knew this one. This somehow address the hard thing of creating a "View" in EE and ProcessWire. I think it lacks thorough documentation though.
- WordPress+WP-Types plugin - very easy to use, you just click and click and it's done. But I don't like WordPress Don't ask me why...
- Drupal 8 - I have never used Drupal before and I just tested Drupal 8 (beta?). Its UI is a little bit confusing but it can do the steps outlined above. But IMO it's very bloated CMF
- Craft CMS - a new one but without built-in categorization of content
Regarding the Resource Manager, I think it can be turn into a CMF if:
- it has custom fields
- it can have multiple instances of RM
- each instance of RM can have different custom fields
