Extension proposal for TouristAttraction class

Hi all,
one of my students, Elisabetta Triolo, is working on a proposal of a host extension for the TouristAttraction class of Schema.org.
She studied the structure of some important tourism platforms such as TripAdvisor <https://www.tripadvisor.it/>, ParisInfo <http://www.parisinfo.com/>, Gogobot <https://www.gogobot.com/>, and she tried to define what a tourist attraction is, by reading information and publications such as the Wikipedia definition <https://en.wikipedia.org/wiki/Tourist_attraction>, the Lorenzo Canova’s study of attractions <http://www00.unibg.it/dati/corsi/3091/12779-Il%20prodotto%20turistico.pdf>, Lucia Varra’s article <https://books.google.it/books?id=5tKk5ElLyhwC&pg=PA17&lpg=PA17&dq=La+destinazione+turistica+come+prodotto++di+relazioni+operative+e+cognitive:+il+ruolo++dell%E2%80%99OTD+nel+governo+delle+relazioni++interorganizzative+e+nei+processi+di+sviluppo++del+territorio&source=bl&ots=HB-XpGTL75&sig=ASp7Os5xL0SrFZt2mLIAJpN8iJg&hl=it&sa=X&ved=0ahUKEwi9q6mo15PPAhUEKsAKHZiGB_kQ6AEIKjAC#v=onepage&q&f=false> about tourist destination.
The whole extension has been published here <http://tourism.sdo-touristattr-extension.appspot.com/TouristAttraction>. 
In addition, an owl version of the extension is available here <https://github.com/alod83/tourpedia-attraction/blob/master/ontology/schemaorgTouristAttraction.owl> and it’s possible to find an explanation of the project here <https://github.com/alod83/schemaorg_tourist_attraction/wiki>.

It’s important for us to have feedback from the community, in order to improve the structure of the class and its subclasses, and, hopefully, add this as an host extension of the Schema.org project.
Thanks in advance for your attention,
Angelica
