I'm trying to figure out how to find out if there's a good standard format for sharing business information such as:

Business Name
Address - well-defined fields
Lat,Lng Coords
Business Type - maybe from a well-defined enum, my starting point contains Retail,Food,Drink,Coffee,Service
Hours of operation - including a spot for 'except laksdasd' or 'sometimes we open late' which could be just plain language
Business Keywords - don't know if this is asking too much. how well do http meta tags work in practice?

So, if no such thing exists, is this something I can submit to IETF?

I can't currently find it on http://www.rfc-editor.org/cgi-bin/rfcsearch.pl , and vCard doesn't suit my needs.. Thanks!
