Star Trek: Deep Space Nine alias and implications

Alias:  
Deep Space Nine <=> Star Trek Deep Space Nine  
There don’t seem to be many pictures that are explicitly about the space station, so I think it’s safe to alias this. Not sure which tag to keep, though. Deep Space Nine has more pictures, but Star Trek: Deep Space Nine is the full title. (Should we add the : to the tag?)
 
Implication:  
Deep Space Nine -> Star Trek

I did the alias as an implication instead for semantic/searching reasons. Best we don’t start deciding a thing that already has a separate tag gets aliased to what’s named after it.
