schema.org may have some potential, but it's not clear to me how the LocalBusiness/openingHours is supposed to work with anything but regular hours...
Here's how openingHours are described at http://schema.org/LocalBusiness """ The opening hours for a business. Opening hours can be specified as a weekly time range, starting with days, then times per day. Multiple days can be listed with commas ',' separating each day. Day or time ranges are specified using a hyphen '-'. - Days are specified using the following two-letter combinations: Mo, Tu, We, Th, Fr, Sa, Su. - Times are specified using 24:00 time. For example, 3pm is specified as 15:00. Here is an example: <time itemprop="openingHours" datetime="Tu,Th 16:00-20:00">Tuesdays and Thursdays 4-8pm</time> """ So how would one indicate different hours on different days? Is there more documentation that I'm missing? If I wanted to create a service to take this data an calculate whether the business is open right now, I'm still stuck having to parse and interpret a text string, which defeats the purpose of having this information encoded as "data".
