This thread is over a year old, and so you are necroposting. Not only that, it has already been revealed that the woman is Yang's mother, Raven, who is not dead.

Yang's story is not that a Grimm attack happened and her mother went missing, but rather that her mother left Yang with her father and walked out. The Grimm attack Qrow saved someone in was in fact when he saved Yang and Ruby after Yang decided to search for her mother without adult supervision.

When Raven said she's saved Yang once, she is talking about when she stepped in and saved Yang from Neo.

And it's uncertain if the location Salem is in is indeed another dimension or world, or simply somewhere on Remnant. Remnant's moon is visible in the background while we are looking at Salem, which does lend credence to the theory of Salem simply being somewhere else in Remnant.

Yang's mother is not dead or kept somewhere like the Underworld, nor does Yang need to go rescue her from such a place at this point of time in the story.
