Dear All, Here is an issue in the latest draft of the Time Ontology http://w3c.github.io/sdw/time/ for discussion and resolution. As said in Issue 9, there is ongoing work in OGC, and ISO on non-Gregorian calendars and time in WKT that is relevant. As there is probably a consensus that Annex B Time Zone and namespace zont is not well developed, I support this proposal to add a stub class for Time Zone. My understanding is that this has been done, so I propose that the issue is resolved but some of the text is left to explain the need for future work. Chris ---------------- 5.8 Class: GeneralDateTimeDescription Issue 10 [No link] The time zone ontology provided in the Annex is immature and incomplete. Use of a tzont:TimeZone from that ontology as the range of an ObjectProperty in OWL-Time creates an implied dependency which is not ideal. We propose adding a stub class time:TimeZone into the main namespace (i.e. no properties) which can then be a super-class or equivalent class to any time zone formalization.(Compare with time:TRS which is handled this way.) ---------------- Chris Little Co-Chair, OGC Meteorology & Oceanography Domain Working Group IT Fellow - Operational Infrastructures Met Office FitzRoy Road Exeter Devon EX1 3PB United Kingdom Tel: +44(0)1392 886278 Fax: +44(0)1392 885681 Mobile: +44(0)7753 880514 E-mail: chris.little@metoffice.gov.uk http://www.metoffice.gov.uk I am normally at work Tuesday, Wednesday and Thursday each week
