Honestly, the API and schema are second to UX to manage the hours. The actual API to the web service is trivial and just a matter of deciding on an interface and schema that you like and that most future-proofs your work. Personally, I would probably disregard it unless it has a JSONP format so that I can easily include it on pages using JavaScript. If it was some overly complex RDF thing I'd only consider it if it had amazing management of the hours. Which brings me to my main point...

It needs to be simple and flexible such that a layman can manage it. Currently tools are designed for easy data transfer to databases, e.g. a list of defaults for a given date range and then dozens of exceptions for specific dates. Most people are overwhelmed that. Consequently, changing hours often involves not only administrative changes but also assistance from technical people. It needs to be simple for admin assistants to "refactor" the hours.

Lastly, from my experience the biggest problem is propagating changes throughout multiple systems. Yes, not all changes can be done by administrative assistants from some single management tool (e.g. systems staff may have to modify the ILS calendar) but there needs to be an easy way to determine the specific changes between each change... Like a diff, so that changes are easy to delegate to appropriate staff. 

Looking over my email, such features would be incredibly difficult to implement well, but at least from my experience they're the actual problems that plague libraries. Honestly, we'll conform to whatever technical implementation you choose (hell, I'd accept some bizarre MARC-encoded hours) so long as you actually tackle the real problems. Otherwise, it's just some web service that can be easily implemented in an hour and is useless.

As those who work in academic libraries know, it's not the *regular* hours, but all the exception dates/hours that are important (Spring break, Maymester, intersession, Christmas holidays, yadda, yadda).  This app knows all the exceptions.

My interest is not in representing the totality of the schedule (again, because of all the exception dates/times) but in representing one day (i.e. today).  So I don't care about representing recurring intervals.
