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
