Adding microdata to tabs

Hello All

i am trying to work out how or if it is possible to add microdata to the profile tabs/boxes in CB.

i am new to joomla and CB, but have managed a few simple plugins and am reasonable with php/sql/html, etc.

could anyone please point me in the right direction to write a plugin to allow for microdata to be added to (all) the tabs/tab box?

Thank you
Jon
