The current scope of OWL-Time is quite clear in this sense - it provides for how to describe time, so that other applications can then use it.

My sense is that the Best Practices paper will where proposals about how to use time|space will arise.

But I am somewhat concerned that the BP will need to roll together both the geometry schema, and the ways to use that, which is a different approach to the time deliverable where concerns are more clearly separated.

Subject: The 'valid time' requirement

Hello Alejandro,

About the Valid time requirement<http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#ValidTime> ('It should be possible to represent the time of validity that applies to a thing, state or fact.'): I wonder why we consider this to be in scope for the time ontology deliverable. It seems to me that the time ontology is about how to express time, not about where and how expressions of time can be used.

Furthermore, if valid time is considered, transaction time can be considered as well. In general, a thing can have multiple associated time dimensions. But I think that is out of scope for the time ontology.

Greetings,
Frans
