Hello, The oldest remaining issue with the UCR document is ISSUE-14 <http://www.w3.org/2015/spatial/track/issues/14>: Not clear Time req. - temporal reasoning and relations (xsd formats). Until now the issue had no related e-mail thread. This message changes that. I hope we can all think about this issue and work towards resolving it - hopefully in next week's meeting. My personal understanding is that this issue could be intended to lead to addition of a new requirement that is the temporal equivalent of the spatial operators requirement <http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#SpatialOperators>. Especially when considering inexact dates and times I think it would be good to have operators like 'before', 'after', 'during' at one's disposal. But when looking at the Time Ontology I see such concepts are already there. I understand them to be only usable with exact dates and times, but there already is a requirement for temporal vagueness <http://w3c.github.io/sdw/UseCases/SDWUseCasesAndRequirements.html#TemporalVagueness>. Could this mean there is no reason to add another requirement?
