The daughter of Gisèle Pelicot has said that her family went public about the case to encourage victims to come forward, speak up and "don't stay in silence".
Ms Pelicot's former husband Dominique Pelicot was found guilty of repeatedly drugging and raping her for almost a decade, and inviting dozens of strangers to rape her unconscious body in their home.
He was sentenced to 20 years in prison.
Speaking on RTÉ Radio One’s Brendan O'Connor, Caroline Darian, Ms Pelicot’s daughter, said that despite her message of hope, the sentences handed down to the men involved in the rape trial were not long enough.

"It was supposed to be the historical trial of chemical submission in France. I’m not satisfied with the final verdict," she said.
Despite this, Ms Darian said that the verdict handed down last month gives courage to other people impacted by sexual assault, who can speak up and know that they are allowed to do so.
If the trial had not been made public, she said it would have been a gift to sexual abusers, including her father, and doing so was the only way for all of those involved to face up to their crimes.
She added that the family knew it would be helpful for society in general to open the door to this case.
During the criminal process, Ms Darian was shown pictures of her body in an unconscious state by police, which she explained showed her in a similar position to that of her mother.
She described being shocked when she saw the photographs, realising that she was not asleep, but drugged.
"It took me a while to realise it was me in the pictures, as they were taken at different times in different places," she said.
Ms Darian said she also did not believe her father told the entire truth during the trial, adding "we don’t know yet how many sexual abusers went and raped my mum".
She said that before knowing what happened to her and her mother, she was pretty close to her father and described him as supportive.
"We were a really united family, and I really trusted him," she said, adding she "felt abandoned" by her father.
She said: "I didn’t know him.
"I knew the face A but not the face B.
"The previous father I had died. The one that I thought he was probably never existed and didn’t exist beforehand.
"It's over, he doesn’t exist anymore."
From prison, Ms Darian said, her father tried to emotionally maintain control of his then-wife and family through letters in which he asked for help and for the family not to let him down.
She described her father as "a really dangerous man, a sexual abuser and manipulator".
"He's a criminal ... that's why I will never call him dad again," she added.
"He had a wonderful family, he had everything," she said, adding "he’s a sexual pervert".
"There's no other reason why he would do this," she said.
She said that she and her siblings, David and Florian, found the trial "so hard", specifically because of how those on trial were "behaving".
"It was a big ordeal to go through and it's not that easy to go through it, nothing prepares you for it," she said.
Ms Darian, speaking after the publication of her memoir, said she wanted to take something more noble from the process, adding "I had to live with this legacy in my life".
"I really wanted to make something bigger than what we went through as a family, to find a kind of sense in what we have to deal with," she added.
Ms Darian founded a charity, Mendors Paswhich, which translates to "don’t put me under".
Its aim is to drive awareness on chemical submission and to help victims get support.
She said that this area was a public health issue, not just in France but across the world.
Despite having psychiatric help herself during the process, she said, there was a need for the care system for victims in France to improve and that laws need to be changed.
She said her charity aims to create a well-resourced training programme for health professionals and is involved in political lobbying too.
Ms Darian also noted the importance of education, adding that parents need to educate their children about sexual abuse to change the future.
