Tourism Schema

Hi All,

We are a small company of consultants in the tourism industry focused on 
helping tourist destinations and services to market themselves.
For that purpose we have recently built a web platform 
<http://www.inventrip.com>, which makes heavy use of tourism categories 
to describe places the tourists can visit or things they can do.

We would like to migrate the existing categories in our platform to 
schema.org classes, however that would require extending classes (e.g. 
TouristAttraction) to cover up more detailed use cases frequent in the 
tourism industry.

Therefore, I would like to join any subgroup interested in Tourism, or 
create one with your help if such group does not exist.

Many thanks in advance for your support.

Best,
Felipe Santi
