Changed rdf:XMLLiteral so that it doesn't require XML canonicalization. This means implementations and authors can use it in the obvious way. Added xsd:duration. Added the new XSD 1.1 datatypes xsd:dayTimeDuration,xsd:yearMonthDuration and xsd:dateTimeStamp . All literals, including language-tagged ones, now have a data type in the abstract syntax. Will make APIs more internally consistent. Richard On 9 Apr 2013, at 02:09, Sandro Hawke <sandro@w3.org> wrote: > Tomorrow evening [1] I'm presenting about all the cool new stuff in RDF 1.1.
