Hi, I was wandering maybe someone have any advice how to approach modeling the following construction that is in my opinion closely related to your question but stated in somewhat more general manner:
Let us given an event of type E that is scheduled for a given time t(E) and that lasts specified time length (without any loss of generality we may assume it lasts for 1ms). Let us also given a specified time interval of type TI during which we perform observation for events (we assume from 1PM to 2PM, for example). So, how should we describe the following: 1) In TI only events of type E may happen. 2) In TI every t(E) must be round number of seconds. 3) In TI events of type E do not overlap. I would really appreciate any pointers to how to model this in RDF/OWL.
