Is adding a Bricklink reference enough to republish a part

[Manfred Schaefer]

I sent a DAT file of an existing part (minifig head) to the PTAdmin to upload this file to the Part Tracker. I just added a Bricklink reference.
I received a message during the verification process that just adding a Bricklink reference is not enough to republish this part.
From my point of view, a Bricklink reference is very helpful. I found more minifig heads that need a Bricklink reference.
What is the statement from the community, is it okay or is that not enough to republish a part?
