I'm kay with having these articles. The writers have said that the upcoming characters in season 4 are from 'Frozen', but the show's universe is obviously seperate from the entire Disney universe. Here's what they have said:

What’s your biggest concern taking this on creatively? Horowitz: To do it justice. We would never want to re-do the movie. But we want this to feel like a part of [the movie] and feel a part of our show. We want it to walk that line of being part of the  Once Upon a Time universe, but also feel like part of the  Frozen world.

Kitsis: In the past, like, we made Peter Pan villainous, we’ve taken liberties with certain characters. This is a situation where everybody was on the same page. Adam and I were looking to bring the spirit of Elsa [on  Once played by Georgina Haig] and Anna [Elizabeth Lail] into our show. We’re not looking to do a sequel, we’re just looking to bring them into our world for a fun story arc. So character and storywise, we just wanted to honor the characters. And with how recent the movie is, that was important to Disney as well.

Kitsis:  We felt there was a way to do this in a fun way in our show, but not doing anything that might harm a sequel or anything they might do in the future. So fans can have fun, but rest assured we’re not trying to do anything that might harm the franchise.

"Though not a sequel, your arc does take place after the events in the film, right?

Kitsis: Yeah, simply because what happened in the film was so beautiful. We’re picking up these characters after the movie.

The Peter Pan is this show was clearly not the same character from the 1953 Disney movie. Even though Neal told Mulan they made a movie about Mulan, we don't know if her backstory is exactly the same as the title character from the cartoon. The only thing we know about her past from the episode "The Outsider" was that she did serve in the Emporor's Army in Native Land, which did occur in the film, but we have yet to come across other characters from that universe. There is no actual Beast from Beauty and the Beast. Rumplestilskin was serves as the "Beast"for our story. The characters from Robin Hood are not animals like in the 1973 film. And as we all know, there was another "Sleeping Beauty" before Aurora in this TV show.
