Dear All, Here is the summary of the marked issues in the latest draft of the Time Ontology http://w3c.github.io/sdw/time/ . My proposal is that the issue is valid, but the work is out of scope of the revised Time ontology, and we can delete it from the document. Because I also have concerns about the detailed syntax orientated aspects of the EDTF proposal, I propose that we do not make any informative mention on the proposal. Chris ---------------- Section 2 Changes from previous versions Issue 3 https://www.w3.org/2015/spatial/track/issues/26 Temporal vagueness requirement. Extended Data/Time Format (EDTF) is a detailed proposal for how to encode temporal vagueness, and some other concerns, by extending the xsd:dateTime syntax. The editors consider that would be the wrong direction since it would make the encoding inconsistent with all XSD-based processors. On the other hand, specific RDF properties matching the ones proposed in EDTF could be used to make it amenable to RDF reasoning. However, we should consider doing this in a separate namespace. Note that some of the concerns in EDTF are already accommodated in OWL-Time (e.g. 'unspecified' appears to only require the timeUnit to be chosen appropriately). ---------------- 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
