Plugin fields && validation

[Web-Media]

 Hy all .. 
Should be a class where plugins can communicate with each other & plugins communicate with the core .
A class where plugins to declare required "custom" fields and core to be aware of required fields .
Right now there is just js validate method and it's done inside plugin .
We need  a plugin fields class and a  core  php validation  class . 
 This  is a starting point .

 Waiting for your ideas and contributions . 
Thanks !
