What is google connection

Now, my site is listed in dmoz directories, but not in google directories. Why? Should I submit my site again?:icon_ques

No, there is no need to suggest your site again.
Google directory is a copy of DMOZ directory.
Each week DMOZ produces an RDF file with all listings.
Everybody can take this RDF file to create a copy directory.
DMOZ can not control when and if these copies will be updated.
So if you want to know when Google is going to update their directory you will have to ask Google.
