Isn't it a SPARQL specific way of writing 1 as shortcu for "1"^^xsd:integer or is that also in Turtle? Also, is a pure RDFS systems (without any additional datatype support) required to read any datatype? I imagine most systems will happily read properly typed literals and if 1 is a Turtle abbreviation for "1"^^xsd:integer, then it should be fine I guess, but I am not sure whether they MUST anything of the form "..."^^URI.
