Hello. I'm happy to file a separate issue on this, but thought it would be good to augment this thread a little. The [SOSA iPhone Barometer example](https://www.w3.org/TR/vocab-ssn/#iphone_barometer-sosa) includes two usages of `sosa:resultTime`. The usage attached to `<Observation/346344>` is as a `owl:DatatypeProperty`, which also matches the definition in the SOSA ontology file. The usage attached to `<Observation/346345>` is as an `owl:ObjectProperty`, having a `time:Instant` as its triple-object. Usage of `resultTime` in both of these manners is a violation of OWL 2 DL's disjointedness of `ObjectProperty`s from `DatatypeProperty`s. Circling back to @edmondchuc 's requested relaxation: Is the intent to still keep `resultTime` as a `DatatypeProperty`? Or, with the removal of the range specification, is the intent to make `resultTime` into an `ObjectProperty` with `time:Instant` as the range, in satisfaction of the not-quite-guaranteed availability of timestamp precision? If it's helpful for the example OWL 2 DL error to be raised as a separate Issue, I'm happy to file that if anyone suggests I do. -- GitHub Notification of comment by ajnelson-nist Please view or discuss this issue at https://github.com/w3c/sdw/issues/1338#issuecomment-1168144019 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
