What does dragon breath smell like? (pawb.social)

I got my hands on MPEG-V standard documents which lets me inject "SEM" (sensory effect metadata) inside .mp4 files which would let me program real world stuff on cues like lights, chair movements, water sprays, etc. So literally if I had a NAS with a hoard of movies and bought the right equipment, i could make 4DX at home.

There's an effect description named "scent", which would, obviously, spray some aromatizer or something in the room. I checked out the standard list of scents that can be applied. There are scents like rose, lavender, mint, apples, mixed herbs, but i came across an interesting one which is the one i'm asking for.


  Scent of dragons breath
  Describes the scent of dragons breath

Maybe this is a weird reason to ask this... I really want to know out of curiosity if this "dragon breath" would be some specific mix of herbs or incense or any kind of room spray. I sense it would kind of be an artificial scent... but idk... really... Would it really work if i coded a "Home 4DX" version of the Hobbit movies?

You found it, yay! Except i have an edition from 2019 instead of 2011. Wow this standard is so old yet no one had the idea to implement such thing for home cinema?

Honestly yea, fuck the paywalls. Though some german user uploaded a full list of standards updated to 2021, including ISO, DIN, IEC, IEEE, ASTM, so many others. They're available for free now. They sometimes include the CD-ROM files, but i don't think the document i got is my case
