Which is best, inherit from sys:base or cm:content

[mohammed_amr]

What is the difference between content model inherit the sys:base, and another one inherit cm:content and which is best to used as parent for my content model and what are the criterion that i need to consider to take a decision  ?

I have sys:base, cm:cmobject and cm:content and my be others. what are the differences between all of them and what is the best one i can use it as parent to my content model ?

In other words, is there any advantage to inherit one of them over another ?

Thanks

It rather depends upon whether you have some content :roll:      In general most things in alfresco are cm:content,  but there's important things like folders, people and groups that don't.

Can you advise me about the criterion must be enforced to take a certain path in the development and what are the impacts for two type of paths.

Can you look at the content model
