adding events in space ontology

[SahaPratik6267]

hallo,

I am working on a university scenario where the system is should be designed like this,

The building has different rooms and cafe ,library etc

Now I want to connect it with time part so the questions should be like--

1. There were no students detected in front of library today why? The answer is: its weekend or public holiday.
   in this sense I divided the time part into 3 category

Building->has->buildingschedule->schema:events->eventdays->schedule
->has >nonworkingdays>event>public holiday>schedule
>event>semester break>schedule
>event>weekend>schedule

now my question is how do I design such system? is there any example for such system where we might have to decide what kind of holiday it is.

Kind Regards
Pratik
