If you need any other name beside Luxarti - something on the lines with 'Scent Library' for Oud-related materials, there are options to explore, and probably to make up a novel name, like Oudoteque, or 'Scentopedia';
you can even launch a contest for the best name for such a platform - with a little prize for one who will come up with the best suggestion that you will like. But 'Osmoteque' is better to be dropped off - for two reasons - avoiding any confusion with well-established institution, and for preventing any potential legal ramifications that may arise in any future (near as distant) from the people of the Osmoteque in Versailles, once your site will gain popularity (I am sure of it) - especially since there is a commercial element to it.
If you define exactly, in a couple of sentences, the overall description yet with some key details, of that virtual place (and how it is different from what Luxarti is, is it beyond Oud-related materials etc.), sure I will give a thought about a catchy name 🙂
Auspicious name is a lucky blessing for any enterprise, but especially for a new one - and in our age of internet instant connectivity and the fast (occasionally viral) spread of information, it is so much better if the name is your own, unique - 'fresh' - and free of any controversy down the road.
