Product mapping is very important specially genric brand. It also stops duplicate product listing.

Some limitations -(1.) any admin seller can edit genric product description, title with the permission admin. Admit kept his approval for final discussion.

(2.) If registered brand allowed to any seller for product mapping the othorised brand can change product description and title and images. Admit kept his approval for final discussion.

So that's a basic. Once martvill author accept I will share more thought.

Thanks
