This comment concerns the RDF conversion of datetime values. Since literals in RDF are datatyped, it would be appropriate to map any values that were obtained from a datetime attribute to the respective datatype. In other words, if the datetime attribute contains a time, then the RDF conversion should generate an xsd:time typed literal; xsd:date for a date, and xsd:dateTime for a date and time. 48986 1 ian 2011-05-31 23:22:48 +0000 That seems reasonable... do I just change the spec to say that when it comes from a <time> element, the generated triple is in fact a quad and the fourth field is a "type" with the URL corresponding to the appropriate xsd:* type name? 49844 2 richard 2011-06-18 20:19:10 +0000 Instead of a "plain literal", you generate a "typed literal", which has a "datatype URI". http://www.w3.org/TR/rdf-concepts/#dfn-typed-literal http://www.w3.org/TR/rdf-concepts/#dfn-datatype-URI Something like this should work: If element is a time element, and value is a valid date or time string, then: - Let value be a typed literal - If value is a valid date string, then the datatype URI is http://www.w3.org/2001/XMLSchema#date - If value is a valid time string, then the datatype URI is http://www.w3.org/2001/XMLSchema#time - If value is a valid global date and time string, then the datatype URI is http://www.w3.org/2001/XMLSchema#dateTime 49980 3 ian 2011-06-21 06:52:43 +0000 Thanks, will do. 50822 4 ian 2011-07-07 23:33:21 +0000 Turns out there's actually a comment in the source saying I should do this. :-) I'm delaying fixing this a little longer, however, because there's a chance we're going to drop <time> altogether in favour of a more generic mechanism for machine-readable data. 52995 5 mike 2011-08-04 05:05:52 +0000 mass-move component to LC1 54791 6 ian 2011-08-12 20:20:48 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
