Is Domino Document Manager a dead Product? Reply needed

I would like to know whether Domino Document Manager is a dead product since IBM believes it is in maintenance mode.

We are in the process of thinking of implementing this product which we have reasons to believe is an appropriate product for us.

Could anyone guide me in this regard?
